Astrocytes functionally interact with neurons and with other brain cells. Although not
electrically excitable, astrocytes display a complex repertoire of intracellular Ca2+ signalling …

Highlights•There are several promising techniques for processing calcium imaging
data.•Comparing the accuracy of these methods is difficult, due to lack of ground truth.•The …

Rapid eye movement (REM) sleep is accompanied by intense cortical activity, underlying its
wake-like electroencephalogram. The neural activity inducing REM sleep is thought to …

We developed a miniaturized two-photon microscope (MINI2P) for fast, high-resolution,
multiplane calcium imaging of over 1,000 neurons at a time in freely moving mice. With a …

We assembled a semi-automated reconstruction of L2/3 mouse primary visual cortex from∼
250× 140× 90 μm 3 of electron microscopic images, including pyramidal and non-pyramidal …

INTRODUCTION In the absence of sensory inputs, the brain produces structured patterns of
activity, which can be as large as or larger than sensory-driven activity. Ongoing activity …

The meta-reinforcement learning (meta-RL) framework, which involves RL over multiple
timescales, has been successful in training deep RL models that generalize to new …

Animals associate cues with outcomes and update these associations as new information is
presented. This requires the hippocampus, yet how hippocampal neurons track changes in …

A neuronal population encodes information most efficiently when its stimulus responses are
high-dimensional and uncorrelated, and most robustly when they are lower-dimensional …

The perception of fat evokes strong appetitive and consummatory responses. Here we show
that fat stimuli can induce behavioural attraction even in the absence of a functional taste …
