tag:techtv.mit.edu,:Array/185689620 2008-02-22 15:45:35 -0500 MIT News Office High-speed videography, developed by MIT researchers, reveals <a href="http://web.mit.edu/newsoffice/2008/whiskers-0227.html">how a rat uses its whiskers</a> to explore a textured surface. An automated algorithm is used to analyze the whisker micromotions, which are thought to underlie rats’ highly developed abilities to perceive tactile objects and distinguish textures. This video was captured at 3202 frames per second, so on most computers the playback will be slowed down by about 100x.<br /> <br />Video courtesy of Jason Ritt, McGovern Institute for Brain Research at MIT 20 tag:techtv.mit.edu,:Array/185630120 2007-11-19 16:10:03 -0500 MIT News Office This time lapse video shows development of a normal neuron (left) and a mutated neuron that does not express the Ena/VASP proteins. Cultured for two days, the normal one extends an axon and many dendrites, while the mutated neuron fails to make such extensions. <a href="http://web.mit.edu/newsoffice/2007/nerves-1119.html">Full story</a><br />Video / Erik Dent and Frank Gertler 18 tag:techtv.mit.edu,:Array/185610040 2009-05-21 11:51:27 -0400 MIT OpenCourseWare In this session: Overview of cognition<br /><br />Thought, learning, perception, reasoning, and language are all cognitive abilities powered by the soft squishy gray stuff inside our skulls. After a quick-and-dirty introduction to neurons and the brain, we'll examine several aspects of human cognition and look at the neurophysiology that underlies them. We'll also discuss methods used to study these areas, read some current research, and navigate the wilds of the science library. 1951 tag:techtv.mit.edu,:Array/185579720 2009-07-23 13:59:28 -0400 MIT OpenCourseWare In this session: Learning and long term potentiation<br><br>Thought, learning, perception, reasoning, and language are all cognitive abilities powered by the soft squishy gray stuff inside our skulls.
