ABSTRACT
Neurocomputational models provide fundamental insights towards understanding the human brain circuits for learning new associations and organizing our world into appropriate categories. In this talk I will review the information-processing functions of four interacting brain systems for learning and categorization:
(1) the basal ganglia which incrementally adjusts choice behaviors using environmental feedback about the consequences of our actions,
(2) the hippocampus which supports learning in other brain regions through the creation of new stimulus representations (and, hence, new similarity relationships) that reflect important statistical regularities in the environment,
(3) the medial septum which works in a feedback-loop with the hippocampus, using novelty-detection to alter the rate at which stimulus representations are updated through experience,
(4) the frontal lobes which provide for selective attention and executive control of learning and memory.
The computational models to be described have been evaluated through a variety of empirical methodoligies including human functional brain imaging, studies of patients with localized brain damage due to injury or early-stage neurodegenerative diseases, behavioral genetic studies of naturally-occuring individual variability, as well as comparative lesion and genetic studies with rodents. Our applications of these models to engineering and computer science including automated anomaly detection systems for mechanical fault diagnosis on US Navy helicopters and submarines as well more recent contributions to the DoD's DARPA program for Biologically Inspired Cognitive Architectures (BICA).
Speaker: Dr. Mark Gluck Mark Gluck is a Professor of Neuroscience at Rutgers University - Newark, co-director of the Rutgers Memory Disorders Project, and publisher of the public health newsletter, Memory Loss and the Brain. He works at the interface between neuroscience, psychology, and computer science, where his research focuses on the neural bases of learning and memory, and the consequences of memory loss due to aging, trauma, and disease. He is the co-author of "Gateway to Memory: An Introduction to Neural Network Models of the Hippocampus and Memory " (MIT Press, 2001) and a forthcoming undergraduate textbook, "Learning and Memory: From Brain to Behavior." He has edited several other books and has published over 60 scientific journal articles. His awards include the Distinguished Scientific Award for Early Career Contributions from the American Psychological Society and the Young Investigator Award for Cognitive and Neural Sciences from the Office of Naval Research. In 1996, he was awarded a NSF Presidential Early Career Award for Scientists and Engineers by President Bill Clinton. For more information, see http://www.gluck.edu.

Please check out a great Children's book about Autism, PDD and ADHD called 'Why Is He Different?' (Please spread the word about this unique book, tell your friends and tell me what you think about it. Big thanks!!). You can preview it on youtube profile called Monalisaknew. Just copy and paste the following sentence in youtube search window: 'Why Is He Different? (Autism Book)' You can also buy this book on AthsePublishing(dot)com. Thank You !!
StillDigitalStudios youtube video has some good info on advertising buy doesnt take this long to say it all and has really cool grappics too. i just looked at his youtuve vid and website.
OH! 'mt potato' head!! the dude-ette from gitmo, that should have read Cornell law, before he made pres.. you know the dude with the turquoise gloves, glasses and 'stache

the navy and sonar? how about livermore and radar? livermore and radio? is this a dating lesson?? or os it a leeson on 2 patterns 'remembered" nukes and concrete? is that a tomatoe can? a representational nuke[plant]? is that the water factor to cool any nuke[plant]? and then, phase 5? is darpa naughty? last i read a WIRED [2 reads] darpa cansent a radio signal thru a wal [?] darpa can;t send a radio signal thru a wall[?] livermore can send a signal thru a wall?

what would william james do?
lawl i wonder if some people found that offensive. i found it to be lolable.
You can also buy this book on AthsePublishing(dot)com. Thank You !!

'mr america' every palin-ettes boyfriend.
give him a button and he might blow up LA?
liked wagner [the musican]
et al?

how about livermore and radar?
livermore and radio?
is this a dating lesson??
or os it a leeson on 2 patterns 'remembered"
nukes and concrete?
is that a tomatoe can?
a representational nuke[plant]?
is that the water factor to cool any nuke[plant]?
and then,
phase 5?
is darpa naughty?
last i read a WIRED [2 reads]
darpa cansent a radio signal thru a wal [?]
darpa can;t send a radio signal thru a wall[?]
livermore can send a signal thru a wall?
