As the Marr intro chapter explains so beautifully, there are many levels of analysis in cognitive science and cognitive neuroscience. Units in deep nets are very different from actual neurons, and the backprop methods used to train deep nets have no resemblance to how human brains get wired up. But for the case of object recognition at the level of representation, there are striking similarities between deep nets opt…

I work with neural networks for complex scene processing and object detection on the roads. Best of part of my job is watching a network "learn/train itself" to classify various object categories. Are there any good theories on what happens during the training process of the brain (for example, while learning a new skill or something very basic/simple) and how individual neurons get affected by this "learning" proces…

Here is one cool example: https://www.sciencedirect.com/science/article/pii/S089662731... And this one I have not read but is by reputable people in a good journal and looks fun: https://www.sciencedirect.com/science/article/pii/S089662731...

Thank you! It means so much to me that some people are appreciating these lectures. I knocked myself out all spring preparing this course, and it was quite a gut punch to read my course evaluations a few days ago, which ere pretty negative. I was so dispirited, I was actually thinking of stopping posting the lectures, but if you guys/gals are into it, that is awesome,I will keep at it! To answer your question: yes we…

Hi, as a recent undergraduate at an engineering school in the Boston area, I can truthfully say these are some of the best lectures that I’ve been exposed to on a technical topic. Thanks for publishing them to the public. Students are so needlessly cruel on course evals!

Students in a typical undergrad environment are replicating Calhoun's rats in a cage experiments. In an explicitly competetive environment no less.

Aberrant behaviour should be expected.

Thank you for this! I used it to make a little script to download audio from each lecture: youtube-dl --get-id https://www.youtube.com/playlist?list=PLyGKBDfnk-iAQx4Kw9JeVqspbg77sfAK0 -i > ids.txt while read id; do youtube-dl -f bestaudio https://www.youtube.com/watch?v=$id done

AFAIK, youtube-dl will find all videos and download them if fed a playlist URL. I'm curious if this script is a workaround for some obscure brokenness or something.

youtube-dl already has extract audio feature built in. try youtube-dl -x playlist-url

Hi all- I am so psyched to see that some are finding the videos interesting! Do send comments if you have them. cheers, Nancy

Hi Nancy, Any chance you've got material covering motor systems instead of the visual sensory systems?

Sorry, I did not cover the motor system in the course.

I've watched the first two videos. You're an engaging lecturer and this is a fascinating subject. Thanks for putting them online.

I have an MA in philosophy and your friendly dig at philosophers' penchant for stuff like "undetached rabbit parts" made me lol.

Thanks, both of them look really relevant. Will read. :)

Thanks for all of this Nancy. I'm just a software engineer but I find the connection between technology and the brain intriguing. The brain seems incredibly complex but I'm glad we have content like yours to at least guide us in understanding it.

Ah. I knew there was a rational explanation :) I missed that bit.
