Tatiana Engel explains how to connect high-dimensional neural circuitry with low-dimensional cognitive functions

Neuroscientists have long sought to understand the relationship between structure and function in the vast connectivity and activity patterns in the brain. Engel discusses her modeling approach to discovering the hidden patterns that connect the two.

Local circuit loops within body control fly behavior, new ‘embodied’ connectome reveals

The mapping, which traces how the central nervous system interacts with the rest of the body, challenges the idea that behavior control is centralized.

Worms help untangle brain structure/function mystery

The synaptic connectome of most animals bears little resemblance to functional brain maps, but it can still predict neuronal activity, according to two preprints that tackle the puzzle in C. elegans

Learning in living mice defies classic synaptic plasticity rule

Donald Hebb’s theory—memorably summarized as “cells that fire together, wire together”—does not explain the shifting hippocampal connections in mice learning to navigate a virtual environment, according to a new study.
