Thirty-First Annual Fred Attneave Memorial Lecture: James Haxby
We are pleased to host Professor James Haxby of Dartmouth College for our 31st annual Fred Attneave Memorial Lecture, “Modeling the structure of information encoded in fine-scale cortical topographies”! The lecture is on Friday, March 6th at 4pm in the Gerlinger Hall Alumni Lounge. A reception will follow. Please join us for both!

Modeling the structure of information encoded in fine-scale cortical topographies
The neural representation of information that is shared across brains is encoded in fine-scale functional topographies that vary from brain to brain. Hyperalignment models this shared information in a common information space. Hyperalignment transformations project idiosyncratic individual topographies into the common model information space. These transformations contain topographic basis functions, affording estimates of how shared information in the common model space is instantiated in the idiosyncratic functional topographies of individual brains. This new model of the functional organization of cortex – as multiplexed, overlapping basis functions – captures the idiosyncratic conformations of both coarse-scale topographies, such as retinotopy and category-selectivity in the visual cortices, and fine-scale topographies. Hyperalignment also makes it possible to investigate how information that is encoded in fine-scale topographies differs across brains. These individual differences in cortical function were not accessible with previous methods.
