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

I am about 4 hours in and still into it! Thank you for sharing the lectures.

Just finished the series on Face Recognition. I was wondering if the fusiform face area (FFA) get activated while thinking of someone's face instead of actually looking at one? Might also be interesting to explore the memory of faces in persons with prosopagnosia?

Haven't actuallly googled for these yet. Will do so in a bit.. after the next series of lectures may be.

YouTube playlist of all linked videos: https://www.youtube.com/playlist?list=PLyGKBDfnk-iAQx4Kw9JeV...

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

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 showed long ago that if you close your eyes and imagine a face you turn on the face area, and if you imagine a place you turn on the place area - here is the article: http://web.mit.edu/bcs/nklab/media/pdfs/OCravenKanwisherJOCN... We and others have shown that in developmental prosopagnosia, the deficit is not just in remembering faces, but also in perceiving them. Nancy

Hey Nancy, thanks for doing the lectures. Coolest Online course I ever came across/studied. Love from India.

Hey,I'm at lecture 2.6,you're talking about the recognition of faces and it's relationship with the holistic image view/image processing.

So, can I go ahead and abstract out the ability of mind being discussed? Basically, given a category, this vision processing module in brain is processing different features of the image(here feature in the machine learning sense). And these categories can be hierarchical. Like faces, humans, creatures, this can be a hierarchy that the brain may be referring to when it is trying to identify a face and switches to the mode where it needs a holistic image view rather than some isolated parts of brain. I understand that imagining how this happens biologically(physiologically) is hard for me.

My question is, am I correct in the above inference? I want to suggest an experiment now :D :P

PLEASE DON'T STOP POSTING THEM! PRETTY PLEASE? At least, future generations may appreciate it, right?! :P

Sounds like you got it, more or less. Current views of how object recognition works in the brain are a lot like current deep net models of object recognition (e.g. Alexnet and beyond): a heirarchical series of processing steps in which units at successive processing stages get more selective for specific things, and more invariant to image variation (size, position, lighting, etc). One view of holistic face perception is that it is just the natural consequence of having units tuned to whole faces (or to large portions of the face). But why this should be implemented in humans as a specific category-selective patch of the brain is an open and fascinating question, that I am now hopeful network modeling may inform.

Thanks for the videos! I took intermediate and advanced physiology, so this is more of a refresher. Is there videos for the more advanced courses available too?

This is not a course per se, but there are a lot of good, cutting edge videos by major players in the field here: https://cbmm.mit.edu/videos
