- Neuroscience, psychology and data science merch! Book recommendations!
A great way to support the channel and to help us to keep going is to check out our merch shop! My wife has created tons of really cool neuroscience, data science and psychology themed shirts, mugs and other gifts.

You can also help the channel by checking out one of my favorite neuroscience books! If you're like me though and don't have time for a physical book then consider listening to one of these on Audible. You can get one of these for free by signing up for a free trial. Even if you cancel before the trial is up, our channel still gets some much needed support!

Are you frustrated because you want to read as much as you can but you can never find the time to pick up a book? I noticed as I got older and busier that I was reading less and less every year. Audible was an absolute game changer! I was able to listen to all the books I wanted to and it was all during the down time moments where reading a physical book was impossible (driving my car, doing the dishes, out on a run, working in the yard..). In the last 5 years I've now listened a total of 4 months 20 days and 8 hours and have managed to listen to over 200 books. They do a free trial and give you your first book for free so give it a try and see if you get sucked in like I did.

Consider checking out my udemy course on group dynamics and social psychology!
If you enjoy my lectures than you might also enjoy my online course on group dynamics and the ways in which groups influence our behavior. www.udemy.com/course/social-p...
This is the second lecture in the Cognitive Neuroscience course. From the microscopic world of nervous system cells and neurotransmitters to the macroscopic look at the regions these cells form, we take a generalized tour through the nervous system.

I appreciate how organized the how lecture is
1:00:10 I'm laughing at your joke hehe. Good dad joke!
The dad jokes have only gotten better over the years since this one! haha

😂😂
Love the personality in your presentation style.☺️☺️
Glad you enjoyed it! haha
@@thecellularrepublic9844 I attached your presentation to one of my LinkedIn posts.
Thank you for feeding my brain and helping people have a deeper understanding on the content.
Peace

@@IngeniousDimensions369 The whole point of posting them was to get the information out there for those that wanted a deeper dive! Thanks for sharing it and for helping make that goal more possible! I wish you the best in all your endeavors.
@@thecellularrepublic9844 each person in life is a puzzle piece. The picture comes together in due time.☺️☺️

You study self; excellent! I get the impression of a driving function from the thalamus (i thought hippocampus but, early days) and a transfer function from the cortex. The driving function would form the basis of a memory address... group(?) and compel an illusion of personal identity. I say "illusion" because a drastically different driving function could feel like a completely different self. Driving function selection at a rate if 30hz plus generates lucid states... maybe?
I see the self more as a collection of activation in the default mode network. These regions have long temporal receptive windows and can integrate information over really long intervals from multiple systems including the ones that you mentioned. The most prominent univariate findings in MRI all point to the vMPFC as the area that is the most involved in self referential thought.
This is an absolutely wonderful course - really enjoying it and the structure and flow is excellent. Is there a required reading textbook that goes with these lectures? Also I didn't get the waterboy reference initially, had to google it - made my day!!
I'm really glad that you enjoyed it! Shoot me an email and I can give you some additional resources and give you access to the powerpoints. tguthrie@uoregon.edu
@@thecellularrepublic9844 This is definitely one of the most incredible lecture series I have ever come across with here on UA-cam, and the fact that someone like me, living in the southern part of Africa (Mozambique), has free acesss to such an amazing course is mind-blowing. I'll definitely reach out to you for the slides and reading lists. I really can't thank you enough for putting this up. Love, from Mozambique.🙂
@@martiangulele5210 This is so awesome! This is exactly why this information should be free and available. Thanks again for the kind words and I hope you enjoy the stuff I sent over!
OMG!! You actually said "extracellular ion concentration"! Woohoo!
Greetings! These discussions are truly helpful. On the other hand, I would like to ask if there is a way that we can access the PowerPoint Presentation slides that you use? It will greatly help in reviewing the topics discussed in these videos. Thank you so much!
I'm glad you found the material helpful! Email me at tguthrie@uoregon.edu and I will send you a link to the slides.
You mention shorter connections because of folding; so, pia mater does *not* cover every mm² of cortex? Are you aware of any space between cortex and pia mater and if so, what is the distance between pia mater and cortex?
The folding brings the gray matter on the inside of the folds closer together. The pia is still stretched out on the outside of the gyri and does cover the whole cortical surface. The portions that are closer together because of the folding have always been on the inner side and never had any contact with pia evolutionarily.
@@thecellularrepublic9844 Thx, this is important info for me. Did you leave out a "not"? I see a space and expect a "not" given context. i.e. "..and does (not?) cover..."
@@thecellularrepublic9844 I'm imagining sulci contain cortical "surface"..? .... I'm hearing you say that not only do sulci lack Pia but also that neural connections can grow across sulci; is this correct? Thanks again; i love this stuff!
@@mediocrates3416 Sorry that that wasn't totally clear.. The pia does cover the whole cortical surface including the sulci. i wish I could post a picture here but instead I'll use some imagery. Think of the pia as the skin around your index finger. If you flattened out the finger and spread it out then you would have a layer of skin on top and a thin layer of muscle on the bottom (pretend the bones don't exist). When you fold it all back together though into the shape that it's supposed to be then the skin will cover the entire outside surface and all of the muscle on the inside will now be smushed close together. The muscle on the left side of the finger is now closer to the muscle on the right side of the finger. This is like the neurons on the right side of the gyrus now being closer to the neurons on the left side of the gyrus.
@@thecellularrepublic9844 That does clear it up! Many thx!
