Rarely categorical, always high-dimensional: how the neural code changes along the cortical hierarchy

Posted by dbos Columbia, This Week: Neuroscience

Kavli Affiliate: Eric D. Siggia | Authors: Stefano Fusi and Liam Paninski | Summary: The brain is highly structured both at anatomical and functional levels. However, within individual brain areas, neurons often exhibit very diverse and seemingly disorganized responses. A more careful analysis shows that these neurons can sometimes be grouped together into specialized subpopulations […]

A circuit model for transsaccadic space updating and mislocalization

Posted by dbos Columbia

Kavli Affiliate: Michael Goldberg | Authors: Xiao Wang, Sophia Tsien, Michael E. Goldberg, Mingsha Zhang and Ning Qian | Summary: We perceive a stable, continuous world despite drastic changes of retinal images across saccades. However, while persistent objects in daily life appear stable across saccades, stimuli flashed around saccades can be grossly mislocalized. We address […]
