Dear Viewers of these Videos-
These lectures are from my undergrad course The Human Brain, currently being taught in the spring of 2018 at MIT. Lectures will be added as the course proceeds.
Over time I intent to expand, revise, and improve this set of lectures, for which I would welcome your feedback. If you are a newcommer to these topics and find parts unclear or boring pelase let me know. If you are in the field I would particularly appreciate hearing about any errors you catch or any content that you think should be added or removed.
Just send me an email at ngk@mit.edu.

Description of MIT Course 9.11: The Human Brain
The last quarter century has revealed the functional organization of the human brain in glorious detail, including an unexpectedly precise mapping of specific perceptual and cognitive functions to particular cortical regions. This course surveys the core perceptual and cognitive abilities of the human mind and asks how they are implemented in the brain. Specifically, we will explore in some detail a number of distinct domains of cognition like face recognition, navigation, number, language, music, and social cognition, and the cortical regions and networks that implement these functions. Key themes include the representations, development, and degree of functional specificity of these components of mind and brain. The course also emphasizes the inferences that can (and cannot) be drawn from each of the main methods in human cognitive neuroscience. The course will take students straight to the cutting edge of the field, empowering them to understand and critically evaluate empirical articles in the current literature.

Close your eyes, and walk slowly towards a wall. As you get closer and closer, you will feel the border cells in action.

Nancy these videos are brilliant, I'm a HUGE fan!

This is one of many lectures or talks with Nancy K. and she is awesome. I greatly admire her passion for brain science.

Nancy, I’m currently reading a book called wayfinding by Michael Bond. In one chapter he reviews research on various cells involved in spatial cognition. This clip has helped a lot in getting a better understanding. Your explanation is very clear and you have explained a rather complex topic clearly. Thank you very much. I am subscribing and look forward to more watching clips. 👍👍👍

Scientific fact - grid cells are the "coolest" cells. Yea I can work with that :P Thanks so much for posting these lectures! Very concise and to the point and it's great to learn some interesting background along the way. It would be great if you could link to the original playlist in the description - it's a little difficult to find on the channel page.

Explained so well! I wish you were my lecturer

Awesome !

hexagonal, just like honeycombs, because it takes less matter or energy to create the grid/borders/lines of it while being an efficient/enough detailed grid, than if it was triangles or squares or worse, circles.

i think for the border cells (or boundary vector cells), the idea is that their fields stretch as the space "stretches", so it's likely that it's just the same cell firing to a border as the researchers change the shape of the space. Reference: Lever, C., Burton, S., Jeewajee, A., O’Keefe, J., and Burgess, N. (2009). Boundary vector cells in the subiculum of the hippocampal formation. J. Neurosci. 29, 9771-9777.

If you put a small wall-like barrier in the middle of the square room, would the same border cell that fires for the bottom wall also fire for the barrier if it is oriented the same way?
