Clover-like object vector representations support human spatial cognition

Posted by dbos NTNU

Kavli Affiliate: Jonathan Whitlock | Authors: Marcia Becu, Ivan Markel Krasovec, Pearl Saldanha, Jonathan Whitlock and Christian F Doeller | Summary: Vector-based spatial coding has been demonstrated in rodents, yet its neural basis in humans and its contribution to navigation remain poorly understood. Using a novel spatial updating task, we show that egocentric directional signals […]

Credit Assignment via Behavioral Timescale Synaptic Plasticity: Theoretical Frameworks

Posted by dbos Columbia

Kavli Affiliate: Rui Costa | Authors: Ian Cone, Claudia Clopath and Rui Ponte Costa | Summary: Behavioral Timescale Synaptic Plasticity (BTSP) is a form of synaptic plasticity in which dendritic Ca2+ plateau potentials in hippocampal pyramidal neurons drive rapid place field formation. Unlike traditional learning rules, BTSP learns correlations on the timescales of seconds and […]

The selective dynamics of interruptions at short tandem repeats

Posted by dbos Columbia

Kavli Affiliate: Michael Goldberg | Authors: Michael E Goldberg, Harriet Dashnow, Kelley Harris and Aaron R Quinlan | Summary: Short tandem repeats (STRs) are hotspots of genomic instability that mutate at rates orders of magnitude greater than non-repetitive loci due to frequent replication slippage. Expansions at some STR loci cause Mendelian diseases, while variation at […]

JIP4 deficiency causes a novel lysosome storage disease arising from impaired cystine efflux

Posted by dbos Yale

Kavli Affiliate: Shawn Ferguson | Authors: Layla M Nassar, xiaojian Shi, Agnes Roczniak-Ferguson, Hongying Shen and Shawn M Ferguson | Summary: Lysosomes break down macromolecules, clear cellular waste and recycle nutrients such as cystine. We describe a novel mechanism whereby JIP4 regulates lysosomal cystine storage by controlling the abundance of cystinosin (CTNS), the transporter responsible […]

Temporally-segregated dual functions for Gfi1 in the development of retinal direction-selectivity

Posted by dbos Hopkins

Kavli Affiliate: Alex Kolodkin | Authors: Karina Chaudhari, Luis E Guzman-Clavel and Alex L Kolodkin | Summary: There is great diversity in retinal ganglion cells subtypes in the mouse retina, but little is known about the molecular factors required to generate this subtype diversity. Here, we identify the transcription factor Gfi1 as a conserved driver […]

An improved model for prediction of de novo designed proteins with diverse geometries

Posted by dbos UCSF

Kavli Affiliate: Michael Keiser | Authors: Benjamin Orr, Stephanie E Crilly, Deniz Akpinaroglu, Eleanor Zhu, Michael J. Keiser and Tanja Kortemme | Summary: Nature uses structural variations on protein folds to fine-tune the geometries of proteins for diverse functions, yet deep learning-based de novo protein design methods generate highly regular, idealized protein fold geometries that […]
