TEDLikia

Today I got TEDLikia :) I have watched 4 videos up to now.

The first one was about robots and their emotions, David Hanson the lecturer brought Einstein face robot to the scene. It was fun, Einstein smile and frown to David. At first I thought David is working on brain-like algorithms but he didn't mention anything so I thought he might not use them.


second video was about Prakash institute in India. I like it very much. Parkash is trying to cure blindness of some children and then during their recovery study children's brains to realize how brain learn to see. At first, cured children were able to determine a square and a circle separately but if they saw a circle covered with part of a square they couldn't recognize neither square nor circle. amazingly after recovery children's brains could see things correctly.
their study about how brain learn to see is published in Nature magazine.



The third video was interesting, it was about hallucination. It happens to 10% of people who have visual or hearing loss. The type of hallucination is called Charles Bonnet syndrom. People with this syndrome hallucinate shapes, objects, faces etc... around them. FMRI studies show their Fusiform Gyrus in the temporal lobe becomes active so they see such things. A person of note who has this syndrome is lecturer Oliver Sacks.


Forth one was about brain computer interface. The lecturer showed the ability of her program and headset. A boy came to the stage and his brainwaves(thoughts) move an object in computer.
