An inhibitory plasticity mechanism for world structure inference by hippocampal replay

Posted by klaurent Columbia

Kavli Affiliate: Attila Losonczy | Authors: Zhenrui Liao, Darian Hadjiabadi, Satoshi Terada, Ivan Soltesz and Attila Losonczy | Summary: Summary Memory consolidation assimilates recent experiences into long-term memory. This process requires the replay of learned sequences, though the content of these sequences remains controversial. Recent work has shown that the statistics of replay deviate from […]

A Biophysical Basis for Learning and Transmitting Sensory Predictions

Posted by klaurent Columbia

Kavli Affiliate: Larry Abbott, Nathaniel Sawtell | Authors: Salomon Zev Muller, Larry F Abbott and Nathaniel B Sawtell | Summary: Abstract Homeostatic (anti-Hebbian) forms of synaptic are effective at eliminating “prediction errors” that signal the differences between predicted and actual sensory input. However, such mechanisms appear to preclude the possibility of transmitting the resulting predictions […]

Preservation of prehearing spontaneous activity enables early auditory system development in deaf mice

Posted by klaurent Hopkins

Kavli Affiliate: Dwight Bergles, Patrick Kanold | Authors: Calvin J Kersbergen, Travis A Babola, Patrick O Kanold and Dwight E Bergles | Summary: ABSTRACT Intrinsically generated neural activity propagates through the developing auditory system to promote maturation and refinement of sound processing circuits prior to hearing onset. This early patterned activity is induced by non-sensory […]

Palmitoylation regulates neuropilin-2 localization and function in cortical neurons and conveys specificity to semaphorin signaling via palmitoyl acyltransferases

Posted by klaurent Hopkins

Kavli Affiliate: Alex Kolodkin | Authors: Eleftheria Koropouli, Qiang Wang, Rebeca Mejias-Estevez, Randal Hand, Tao Wang, David D Ginty and Alex L Kolodkin | Summary: ABSTRACT Secreted semaphorin 3F (Sema3F) and semaphorin 3A (Sema3A) exhibit remarkably distinct effects on deep layer excitatory cortical pyramidal neurons; Sema3F mediates dendritic spine pruning, whereas Sema3A promotes the elaboration […]

Spike-phase coupling patterns reveal laminar identity in primate cortex

Posted by klaurent UCSD / Salk

Kavli Affiliate: John Reynolds | Authors: Zachary W Davis, Nicholas M Dotson, Tom Franken, Lyle Muller and John Reynolds | Summary: Abstract The cortical column is one of the fundamental computational circuits in the brain. In order to understand the role neurons in different layers of this circuit play in cortical function it is necessary […]

Kavli Affiliate: Daniel S. Mucida | Authors: Maria Cecilia C. Canesso, Tiago Bruno Castro, Sandra Nakandakari-Higa, Ainsley Lockhart, Daria Esterhazy, Bernardo Sgarbi Reis, Gabriel D Victora and Daniel Mucida | Summary: Abstract The intestinal immune system must concomitantly tolerate food and commensals and protect against pathogens. Dendritic cells (DCs) orchestrate these immune responses by presenting […]
