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.

Longer fMRI brain scans boost reliability—but only to a point
Around 30 minutes of imaging per person seems to be the “sweet spot” for linking functional connectivity differences to traits in an accurate and cost-effective way.

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.

Too much or too little brain synchrony may underlie autism subtypes
Functional connectivity differences in autism mouse models point to two subtypes that correspond to patterns seen in some people with the condition.

Inhibitory cells work in concert to orchestrate neuronal activity in mouse brain
A cubic millimeter of brain tissue, meticulously sectioned, stained and scrutinized over the past seven years, reveals in stunning detail the role of inhibitory interneurons in brain structure and function.

Bespoke photometry system captures variety of dopamine signals in mice
The tool tracks the excitation of an engineered protein that senses dopamine’s absolute levels, including fast and slow fluctuations in real time, and offers new insights into how the signals change across the brain.

Subthalamic plasticity helps mice squelch innate fear responses
When the animals learn that a perceived threat is not dangerous, long-term activity changes in a part of the subthalamus suppress their instinctive fears.
