To Make Language Models Work Better, Researchers Sidestep Language (quantamagazine.org)
Language isn’t always necessary. While it certainly helps in getting across certain ideas, some neuroscientists have argued that many forms of human thought and reasoning don’t require the medium of words and grammar. Sometimes, the argument goes, having to turn ideas into language actually slows down the thought process.

Scientists: Protein IL-17 fights infection, acts on the brain, inducing anxiety (medicalxpress.com)
Immune molecules called cytokines play important roles in the body's defense against infection, helping to control inflammation and coordinating the responses of other immune cells. A growing body of evidence suggests that some of these molecules also influence the brain, leading to behavioral changes during illness.

Functional connectomics spanning multiple areas of mouse visual cortex (nature.com)
Understanding the brain requires understanding neurons’ functional responses to the circuit architecture shaping them. Here we introduce the MICrONS functional connectomics dataset with dense calcium imaging of around 75,000 neurons in primary visual cortex (VISp) and higher visual areas (VISrl, VISal and VISlm) in an awake mouse that is viewing natural and synthetic stimuli.
