Learning or performance? Why the distinction matters for memory science
New methods make it possible to probe the neural substrates of memory with unprecedented precision. Making the most of them demands careful experimental design.

Newly found hypothalamus circuits shape bullying behaviors in mice
Activity in the tiny brain region helps submissive rodents learn to avoid aggressors, and aggressive mice to curb their attacks, according to two recent studies.

What goes up must come down: New marker flags decreased neural activity
Phosphorylation of the metabolic enzyme pyruvate dehydrogenase inversely correlates with neural activity, offering scientists a tool to study inhibition for the first time.

Immune-activation model mice escape infantile amnesia, retain early memories
Male pups born to mothers treated with immune-stimulating molecules show autism-like behaviors and, unlike wildtype animals, do not lose memories formed during early life.

‘VIP’ interneurons may drive autism traits in Dravet syndrome
The inhibitory cells misfire and contribute to social difficulties in mice that model the syndrome.

Unconventional optogenetics technique spurs long-lasting changes in neuronal activity
Conventional optogenetic manipulations to excite or inhibit neurons stop when the light switches off. A new approach makes the changes last.

Visual perception improves in the blink of an eye
Blinking—long considered a problem the brain must overcome to produce seamless vision—may actually be more of a feature than a bug, new research suggests.

Some minimally verbal autistic people show signs of written-language familiarity, study suggests
But researchers not involved in the work worry the findings could be used to support discredited facilitated-communication techniques.
