Abstract representations emerge naturally in neural networks trained to perform multiple tasks

Kavli Affiliate: Stefano Fusi | Authors: W. Jeffrey Johnston and Stefano Fusi | Summary: Humans and other animals demonstrate a remarkable ability to generalize knowledge across distinct contexts and objects during natural behavior. We posit that this ability to generalize arises from a specific representational geometry, that we call abstract and that is referred to […]

A neural mechanism for terminating decisions

Kavli Affiliate: Michael Shadlen | Authors: Gabriel M Stine, Eric M Trautmann, Danique Jeurissen and Michael N Shadlen | Summary: The brain makes decisions by accumulating evidence until there is enough to stop and choose. Neural mechanisms of evidence accumulation are well established in association cortex, but the site and mechanism of termination is unknown. […]

GTP-bound E. coli FtsZ filaments are composed of Tense monomers: A DNP NMR study using interface detection.

Kavli Affiliate: Ann McDermott | Authors: Kelsey M McCoy and Ann E McDermott | Summary: FtsZ filaments are the major structural component of the bacterial Z-ring and are drivers of bacterial division. While crystal structures for FtsZ from some gram positive bacteria in the presence of GTP-analog like compounds suggest the possibility of a high […]

Motor cortex activity across movement speeds is predicted by network-level strategies for generating muscle activity

Kavli Affiliate: Mark Churchland | Authors: Shreya Saxena, Abigail Russo, John Cunningham and Mark M Churchland | Summary: Learned movements can be skillfully performed at different paces. What neural strategies produce this flexibility? Can they be predicted and understood by network modeling? We trained monkeys to perform a cycling task at different speeds, and trained […]

Face familiarity detection with complex synapses

Kavli Affiliate: Stefano Fusi | Authors: Li Ji-An, Fabio Stefanini, Marcus K Benna and Stefano Fusi | Summary: Synaptic plasticity is a complex phenomenon involving multiple biochemical processes that operate on different timescales. We recently showed that this complexity can greatly increase the memory capacity of neural networks when the variables that characterize the synaptic […]

Decision formation in parietal cortex transcends a fixed frame of reference

Kavli Affiliate: Michael N Shadlen | Authors: NaYoung So and Michael N Shadlen | Summary: Neurons in the lateral intraparietal cortex (area LIP) represent the formation of a decision when it is linked to a specific action, such as an eye movement to a choice target. However, these neurons should be unable to represent a […]

Transient oscillations of neural firing rate associated with routing of evidence in a perceptual decision

Kavli Affiliate: Michael Shadlen | Authors: Naomi N Odean, Mehdi Sanayei and Michael N Shadlen | Summary: Abstract To form a perceptual decision the brain must acquire samples of evidence from the environment and incorporate them in computations that mediate choice behavior. While much is known about the neural circuits that process sensory information and […]
