The "Alright Ninja Nerds.." at the end sounds like a reward.. all the hard work you put in to explain all this to us and so well that we understand every single bit is so helpful and legit a blessing.. thank you so much Zach and team
Coincidentally, your neurology series started right when I started studying neuroanatomy and I can't describe how helpful it has been to me. It's almost like I couldn't have done it even half as good without your lectures. Thank you so much for everything.
This is incredible. He is teaching future doctors worldwide better than most professors could. I am forever thankful for the knowledge you have given me.
Not only that. Story time? Used to teach as an associate at my Uni's Psychology Faculty. Our first year students would have to take a massive course in neuroanatomy and physiology of the CNS. Our textbooks were horrible, and I did try to my best to convey the massive curriculum - it just wouldn't stick, though. This is the pre-Corona era we're talking. These are amazing and super informative videos! If we had 'em back in the day, I'd have bought and handed out USBs with the downloaded content, no kidding. One of the most common questions that'd come up on the oral exam was, for example, the Papez Circuit. Like, 1 in 5 odds. The most hated one by the students because of the sheer complexity! I'd usually figure out a way for them to figure it out and talk it through on my exams, but the professors - oh, boy. 0 mercy. However, if any one of my kids gave them HALF an answer of what is provided in the introduction of Zach's video, they'd nail the question with, possibly, the highest mark. I am very busy with finishing medical school right now and building a prosperous hospital with my family, God be willing. Should we succeed, I might go back to teaching at Uni and let my father and sister run the thing (always been more of a scientist than a surgeon :p)! Will improve my teaching based on Zach's, suggest his content, and promote him as an inspiration for my upcoming textbook (a good one, for a change, again, God be willing!)! Advice for neuroscience students (psychology, molecular biology, biology, neuroscience per se, etc.): Learn for your exams using Zach's "Neurology" section! Buy the textbooks, so your professors will be happily "fed" (especially the ego, as it is the part giving you the mark :p), and learn from the guy giving it all to you for free + better! Yours truly, P. White P.S: Way back, even I passed my entire anatomy exam solely thanks to Zach's N. Trigeminus video, but it is a story for another time! xD
I couldn't have said it better!! I'm taking a neurophysiology exam next week (in Greek language) and 'm watching his videos instead of studying my book. Much much more comprehensive and detailed material. Amazing!!
Your interest in teaching to students that too completely free of cost is completely insane and you teach way way way better than those professors which we pay thousands of dollars. You are the best medical professor Dr. Zach. Thank you so much for providing us these kind of lectures which help us understand more about the body.
i appreciate that here on you-tube a lot of useful stuff like your lectures are free. students are struggling to get quality education but they pay for the lecture at university in which professors really don't care they just deliver the stuff and go. thanks for making these playlist for us ZACH !
You are honestly insane at explaining things, I used your videos 4 years ago while I was studying Biomedical Science and now I've begun studying Dentistry and still these videos help me more than my lecturers! Thank you so much :)
Nursing student here. You literally helped me get an A in anatomy and physiology. I have recommended your channel as a resource for nursing students. Can't thank you enough
No. Not to a medical student level. However I wanted to understand more about it rather than the bare minimum which helped me achieve high grades. What I like about this channel is different teaching methods and the way he explains things .
As someone who went to nursing school and now is going to medical school. The content for nursing school like what you need to know here is maybe like 5% of this. For medical school this is all relevant. If you want to learn more good for you!
Clear understanding of anatomy, Covering whole complicated things thoroughly with vivid explanations in a whiteboard within 60 minutes..! You are an actual genius..., Prof. Zach.. Thankfully... from 🇧🇩
Thank you so so much for this! We're having an exam on the Hypothalamus and Limbic System tomorrow and this is really timely and high-yield! I've always been thankful to discover your channel, and I'm glad to tell my friends about it. You really helped me understand various concepts in Med school and continue to do so. Thank you!
Thank you so much doctor.. In a 1 hour video you cover whole things about Hypothalamus so perfectly and easily as well with proper Diagrams and labelling… once again thank you so much
Accidentally I found your channel yesterday .. while I was searching for metabolism ...and I loved with your channel...u t the Best biology teacher for me.... thank you.
9:00 - 16:57 You can't see this other part of the hypothalamus. If you imagine this is the 3rd ventricle. (draws diagram) On both sides of the 3rd ventricle, you have these sheets of grey matter. So here's our 3rd ventricle with the dots. On the sides here is the hypothalamus, and there are two parts of the hypothalamus: Medial portion(this is the portion diagrammed in the video) Lateral portion(this is behind the part diagrammed, we can't see it) Lateral Hypothalamic Nucleus (LHN): One last nucleus we need to remember ( we already talked about the nuclei here in the medial. One nucleus is all the way lateral, it's called the Lateral Hypothalamic Nucleus (LHN) and it spans almost the entire the length of all the zones in the medial portion of the hypothalamus. Functions: 1. Autonomic Nervous System - works with sympathetic (fight/flight) and parasympathetic (rest/digest) systems 2. Endocrine System - master endocrine regulator - very involved in hormone production 3. Limbic System - one of the epicenters, very important*** Limbic System - involved in emotions (such as fear, aggression, anger). Also involved with sexual behaviors/preferences. Feeding behaviors (satiety, hunger). Learning and memory. How is it involved in the limbic system? Mammilary bodies - 2 primary functions: 1. Memory Consolidation - episodic memory 2. Reflex wtih Olfaction (Olfaction is smell, so memory behind smells) The mamillary bodies are connected to a couple structures here: 1. Fornyx: The Hippocampus has struction called the Fornyx, a white matter structure/tract that goes all the way around and connects to the mamillary bodies. So the Fornyx is shaped like a string or wire. 2. Mamalo Thalamic Tract (MTT): connection between mamillary bodies and the nucleus of the thalamus (Anterior Thalamic Nucleus), from the anterior thalamic nucleus, it works its way up to the Singulate Gyrus. and from the Singulate Gyrus (which looks like a thick worm) it works its way down to the hippocampus. So both the Fornyx and the Mamalo Thalamic Tract connect things to the Mamillary Bodies, and both form a loop: Fornyx - connects Hippocampus > Mamillary Bodies MTT- connects Mamillary Bodies > ATN > Singulate Gyrus > Hippocampus We start and end with the hippocampus (Fornyx starts at the hippocampus and MTT ends at the hippocampus). What was the name of this circuit that we talked about with the thalamus? Papaz Circuit, involved with memory. damage to this can lead to Alzheimer's, Wernekes, encephalopathy The other connection, remember the hypothalamus has many functions. There is another struction above the hippocampus, called the Amygdala Amygdala - involved with fear, anger, aggression, olfaction, There are pathways that connect the amygdala to the hypothalamus and some specifically the mamillary bodies. What is the pathway called? StryoTerminalis (ST) There is another small pathway connecting the amygdala to the hypothalamus, a real short one called the Ventral Amygdalafeugal Pathway. Papaz Circuit: circuitry involving the mamillary bodies, .
This neurology video series is immensely helpful. It is very difficult to find the balance between imparting knowledge and having a sense of humor, and you, my friend have successfully become a master in it. Thank you so much, Zach.
incredible lecture, you are a genius, gifted teacher. I am sure nobody in the world could explain this in such a clear, helpful and logical way. Thanks so much.
love youuuu mr murphy god bless you and your family. i really appreciate what you are doing here teaching us in a spectacular fashion that even universities fail to do so. im so happy that i found you. gratitudes.
You are awesome I could only pay a small token of appreciation which you are doing it for last 6 years to me in learning more and more about the brain through your explanation it's so crystal clear that I can literally see the brain ..and I could associate this teaching with cannabinoids system of the body ..as CBD oil works on this 4 gm components hypothalamus of 1600 gm of brain and creates a cascade of benefits to the body I wish the doctors could explain it and trust me you that I can explain it better than anyone including you but I have a gratitude towards you of helping me understand this system by understanding hypothalamus in such details ..I may have watched this video of yours almost 20 times and every time I learn more when I associate with the cannAbinoid system ..I wish I could make videos like you but leave it as it will be a tough competition to you ..just kidding brother ..u r awesome and gratitude to u ..i donated a very little amount to you but the intention is very pure ..you are doing a great job to the community hats off
One of the best personality.😍Love you,Sir.Love you from bangladesh...I am 2nd phase medical student of Bangladesh...But I always keep my focus on this channel jst for your amazing teach on nurology....May you live long....I promissed when I will get my first salary I must will donet your channel willingly.You are not a man jst Love,"THE KIND MAN-(THE HERO)."
from 6:00 to 9:30 Going into the two nodules/nuggets that make up the pituitary gland, imagine a large funnel, called the Tuber Cinerium. It will start narrowing, and that area is called the Infidibulum. Then it extends downwards into your pituitary gland. There are 4 zones : 1. Preoptic Zone (touching bird's beak), has one nucleus - called the medial pre-optic nucleus ( MPON ) Now moving posterior: 2. Supra Optic Zone has lots of nuclei, one is called Supra chiasmatic Nucleus (SCN), another is Supra Optic Nucleus (SON), above that is Para Ventricular Nucleus (PVN), and the last one is the Anterior Hypothalamic Nucleus (AHN) Move posterior again: 3. Tuberal Zone has 3 nuclei: Arcuate Nucleus (ARC) - monster, tons of functions Ventral Medial Nucleus (VMN) - located more anterior or ventral than Dorsal Medial Nucleus (DMN) - located more dorsal Again moving posterior: 4. Mamillary Zone: lines up with Mamillary Bodies, made up of two primary nuclei Mamillary Nuclei (MN) Posterior Hypothalamic Nucleus (PHN) - very important
I seriously have a crush on you Zach 😍😍 The way you make such complicated things so simple indicates your profound knowledge and intelligence,you are very smart.I love you from India
Thank you so much ninja nerd! You are the best lecturer huhu. It's still difficult to process (information overload) but better than by just reading it from the book by myself. Wish me luck in passing my upcoming Neurology exam!
so helpful and clear thank you SO much! as a first year medical student this is making all of the neuroanatomy pieces really finally come together. pray for me my exam is on Monday!!
Very information dense, very challenging video; absolutely loved it! Will be rewarching at least once when I've finished the series on the limbic system and maybe the endocrine system. You do such a good job. Thank you soooo much for what you do, truly gods work.

Can't even tell you how much grateful I am to have found your channel also I've recommended this to manyyy of my friends and they all love your videos❤️
You guys are saving my neuroscience degree...I swear😂 now I’m not scared of whatever I have to learn because I know I’ll understand it thanks to you💜 so thank you!
Well I’m not in any form of educational study (working mummy)and god know why your channel came up but I’m glued to it !!! Fascinating if only I could start back at the beginning of my school life I know I’d want to be an entomologist ... 🤓 thank you
No words can describe our love respect and thanks to this MAN we love you so much Dr zach I'm already loving neuro but you made me fall over n over again just stay healthy ❤❤❤
for those who have not read the description @18:00 The Paraventricular nucleus of hypothalamus ( PVN) releases corticotropin-releasing hormone (CRH) and not the arcuate nucleus.

Excellent Lecturer Dr.Zaharia
Thanks
Thaaaanks!! Made learning much easier, however aside from CRH, TRH is also produced by PVN and not arcuate nuclei

Ok i just got blown away by the entire hypothalamus....awesome ✨✨ tq Ninja nerd ✨
people these days are missing out of THE BEST CHANNEL OF BIG BRAINS EVER
Ya I agree gurl!
I guess that's why the'r, not big brains.....
LOL
Best video in hypothalamus on the entire freaking internet!... Thank you so muchhh sir!
it is a delight to watch these videos... thanks to you for being such a great teacher... we are blessed to have you.
Notes up to 6:00
covering:
hypothalamus
anatomy then function
then nitty gritty - nuclei and functions
pathways / connections between hypothalamus and other structures & their
relevance
hypothalamus is a part of the structure in the brain deep wtihin the cerebrum, a grey matter structure called the diencephalon
it's a component of what's called the diencephalon
structures that make up the diencephalon:
1. Thalamus: epicenter is the blue egg-like structure, called the thalamus, this thalamus is the center, and all of the other names of the components of the diencephalon are named based on their position related to it.
2. if you take the thalamus and move posterior there is a purple gland called the pineal gland. Pineal gland with a couple other structures: habenula, habenular commissure, posterior commissure. Pineal gland with these 3 others make up the epithalamus.
Epithalamus:
Pineal Gland
Habenula
Habenular Commissure
Posterior Commissure
3. Subthalamus: Just a little bit inferior and perhaps a little posterior to the thalamus, there is a maroon structure ( shaped like a bar of soap),
4. Hypothalamus: Interior and inferior to the thalamus, shaded in green
Parts of the hypothalamus:
Mamillary Bodies: a little nucleus/nugget hanging down like an Adam's apple
Pituitary Gland: two nuggets hanging off together (like a gobble)
Optic chiasma: looks like a rope in the beak of the bird (if you imagine the diencephalon as a bird's head). This is where the two optic nerves cross.
Lamina Terminalis: top bridge of the bird's nose - one of the borders, interior nugget is called the Interior Commissure
Hypothalamus is one of the 4 components of the diencephalon
Hypothalamus has zones and nuclei that occupy it

Marvellous explanation....made me easily bring together what initially seemed monstrously hard to understand. Long Live the Ninja Nerds.
the way u explain and relate stuff to each other just works like a charm. thanks a million
Did he just said sorry? OMG zach you are the super hero of us ❤️
Best channel in youtube! You’ve been here since the start of my med school journey! ❤️❤️❤️
I think there is an error, at 25:52 - The dorsomedial nucleus WHEN STIMULATED produces savagery or rage; the ventromedial nucleus, WHEN DAMAGED, produces savagery or rage. (see BRS Neuroanatomy, 6th Edition, 2020, p. 180).
My course work is really packed up but thank God for you Zack. You're a blessing ❤🎉
I can't thank you enough for making what is complex to easy to digest and learn. THANK YOU FROM ALL MY HEART! Big thumbs up!
Wonderful video and Wonderful presentations. So many students from India and world over benefit from your efforts. God bless you 😊
Many many thanks Zach Murphy! Wish you health and wealth, may God bless You! Thanks a lot)👍🏻
Very timely, we are actually on this part of our discussion. Your videos are ALWAYS very informative and helpful 🥺 Thank youuuuuu
Same here, covering this next week in my class and Zac's videos are a great review
Marvellous video I must say
Rest in peace all the courses that i had problems because they ddnt have diagrams, you have the most sensible digramatic illustration..
You are the best youtuber for all medicine student's. ❤️❤️
Thank you
You are really the best! Very thankful for your existence 😭😭😭
Absolutely gorgeous way of teaching this topic... Lots of Love from Pakistan❤
Too much information
But it is essential and worth it
Don’t stop making videos like this
