Toward a quantitative index of consciousness
Переглядів 1,5 тис.5 років тому
Cognitive neuroscientist Olivia Gosseries walks us through two studies in which she and colleagues used simultaneous TMS-EEG to assay the level of consciousness in neurological patients (including tracking the recovery of consciousness of coma patients transitioning from clinically defined "vegetative state" to "emerged from minimally conscious state"!) and in volunteers in an anesthesia-induce...
Studying sleep and consciousness with TMS EEG
Переглядів 6 тис.5 років тому
Why does consciousness fade during non-REM sleep? This is a puzzling question, explains neurophysiologist Marcello Massimini, because the brain does not “shut down” when we fall asleep. Rather, neurons can show comparable firing rates, albeit with different patterns of synchrony from what is seen in wakefulness. Here, Massimini explains how he and his colleagues applied TMS to subjects while th...
Unification for ‘on the fly’ production and comprehension of language
Переглядів 4065 років тому
How do we incorporate incoming words into an unfolding understanding of what we hear or read? Here, Peter Hagoort, a psycholinguist and pioneer in the cognitive neuroscientific study of language, illustrates how neural data - in this case the N400 event-related potential can be used to adjudicate between theoretical accounts of sentence processing.

Think back to the earlier narrated video on “cognitive training” via video game playing, then check this out. Here, cognitive neuroscientist Heleen Slagter demonstrates the remarkable effect that “just thinking” (albeit a very disciplined and rigorously practiced kind of thinking) can have on subsequent attentional performance, as measured via behavior and electrophysiology. For more info/conte...
Stimulating desire: optogenetic stimulation of the central amygdala
Переглядів 7 тис.5 років тому
Earlier in his career, biopsychologist Kent Berridge made a name for himself by, among other things, determining the distinct neural circuitry and neurochemistry that underlie the psychological phenomena of “liking” and “wanting”, respectively. Here, Berridge’s onetime postdoctoral fellow Mike Robinson demonstrates the effects of, as Robinson puts it, optogenetically stimulating “at the interfa...
The neuropsychology of moral judgment
Переглядів 3 тис.5 років тому
How broad is the reach of cognitive neuroscience? Up to this point we've considered work with implications for clinical, cognitive, and social psychology, for other levels of neuroscience, for neurology, for computer science, and for economics. We have tangled with the philosophical question of whether or not humans possess free will. Here, Michael Koenigs and colleagues leverage contemporary m...
The connectomics of Phineas Gage
Переглядів 1,6 тис.5 років тому
This captivating and broad-ranging narrated video from cognitive neuroscientist Jack Van Horn kind ‘reads’ like a pilot for a Netflix series: It ranges from gruesome anecdotes from the first physical exam after Gage’s freak accident all the way through to the modern-day graph theoretic analyses that Van Horn and colleagues used to quantify the extent to which “the story of Mr. Gage … is also a ...
The cognitive neuroscience of free will
Переглядів 2,8 тис.5 років тому
At one time, the home page of the laboratory headed by Dr. John-Dylan Haynes had this statement: “Decisions don’t come from nowhere but they emerge from prior brain activity. Where else should they come from? In theory, it could be possible to trace the causal pathway of a decision all the way back to the big bang. Our research shows that we can trace it back 10 seconds. Compared to the time si...
Adolescent decision making
Переглядів 1,8 тис.5 років тому
Why do adolescents disproportionately engage in risky behavior? In this narrated video, developmental cognitive neuroscientist Leah Somerville explores the hypothesis that part of the answer may be different maturational rates of “a strongly signaling striatum” versus “an intermediate level of prefrontal regulatory function.” Her focus, the regulation of motivated behavior and approach behavior...
The effect of playing action video games on perceptual decision making
Переглядів 8325 років тому
In this narrated video, cognitive psychologist C. Shawn Green walks us through the astounding range of abilities, from contrast sensitivity to task-switching, that can improve as a function of playing first-person-shooter video games. If you already know something about perceptual decision making, particularly its modeling from a signal detection theory framework, think about whether the effect...
Thalamic control of interareal synchrony as a mechanism for cognitive control
Переглядів 1 тис.5 років тому
Oscillatory synchrony strikes again. This narrated video illustrates how the dynamic and selective control of interareal synchrony may be harnessed to accomplish cognitive control, the prioritization of the representation and/or action that is most appropriate for a particular behavioral context, regardless of the default strength of that representation/action. In it, neurophysiologist Yuri Saa...
The development of cognitive control: inhibition or proactive control?
Переглядів 3,8 тис.5 років тому
Computational models are often characterized by their own creators as “toy models” - a perhaps overly pejorative acknowledgment by the scientist that s/he realizes that the model oversimplifies the system that it is simulating. The potential value of such toys, however, is illustrated in this narrated video from developmental-and-computational cognitive neuroscientist Yuko Munakata. Here, the i...
Leveraging graph theory to understand the large scale organization of cognitive control

Mark D’Esposito is a behavioral neurologist, which means that he is expert in diagnosing and understanding how different types of brain damage can affect behavior and cognition. Here, we’re witness to how the melding of this centuries-old tradition with cutting-edge mathematical theory provides insight into why the consequences of a stroke or other insult to the brain can depend more on where t...
Dynamic population coding in prefrontal cortex
Переглядів 1,6 тис.5 років тому
In this narrated video cognitive neuroscientist Mark Stokes takes us by the hand and leads us up to the frayed, cutting edge of methods for analyzing neuronal activity during working memory task performance. In so doing, he illustrates evidence that the retention of information in working memory may be accomplished by temporary changes in synaptic weights, creating so-called “hidden states,” a ...

    Thank you for that great presentation! I have a question regarding the comparison between the classifiers trained on the localizer and those trained on the memory delay period. At 17:40, you mentioned that the activation pattern during the delay period closely resembles the pattern evoked by sensory input. However, I’m curious whether we can confidently make this claim. It seems possible that, although both patterns may lead to similar predictions, they could actually contain very different underlying information. Could you clarify this point?

    if you give humans let's say a vibration whenever they face the north, they gradually get used to it and whenever they dream, they're gonna know whether they're facing the north or not. they're gonna remember their memories in a way that they know whether they were facing the north or not in that particular event. it's like adding another type of scaffold beside the time and space.

What useful information is conveyed from the peak at N2. Is it this that brain generates stronger waves during incongruency than during congruency? Many thanks! for such a beautiful presentation and soothing explanation.

    This kind of dementia as presented in the video appears to effect regions of the temporal lobes which are though to be needed for visual object recognition.So instead of a hub this could be an inability to correctly encode objects that are visually encountered and thus an inability to trigger the proper memory in other regions using visual stimuli. If a central hub structure exists then damage to it should render the individual progressively unresponsive as all representations of information are damaged so in the test the subject shouldn't even be able to reliably comprehend the task or to produce coherent words as responses with progressively worsening symptoms. What you present in the neuron model is essentially the representation of synapses between the regions and not a central hub.Distributed damage to it should be distributed damage appearing throughout the brain.
