New findings reveal surprising role of the cerebellum in reward and social behaviors

A study in rodents found that the brain’s cerebellum — known to play a role in motor coordination — also helps control the brain’s reward circuitry. Researchers found a direct neural connection from the cerebellum to the ventral tegmental area (a bra…

How to rapidly image entire brains at nanoscale resolution

A powerful new technique combines expansion microscopy with lattice light-sheet microscopy for nanoscale imaging of fly and mouse neuronal circuits and their molecular constituents that’s roughly 1,000 times faster than other methods.

Epigenetics contribute to male and female differences in fear memory

In a mouse model of traumatic memory, male mice recall fear-related memories better than female mice, according to a new study.

Acupressure relieves long-term symptoms of breast cancer treatment, study finds

A new study finds acupressure could be a low-cost, at-home solution to a suite of persistent side effects that linger after breast cancer treatment ends.

When activated, ‘social’ brain circuits inhibit feeding behavior in mice

Feeding behavior and social stimulation activate intermingled but distinct brain circuits, and activating one circuit can inhibit the other, according to a new study.

Schizophrenia can be caused by structural abnormality in adolescent brain associated with genetic risk

Schizophrenia could be caused by a genetic mutation that causes a structural abnormality in the brain during adolescence. Therefore testing for the gene SLC39A8, and brain scans for schizophrenia could predict whether or not someone will develop it, re…

Alterations in hippocampal structural connections differentiate between responders of ECT

A new study in people with major depression reports that electroconvulsive therapy (ECT) induces changes in the fibers connecting the hippocampus to brain regions involved in mood and emotion.

Born to run: Just not on cocaine

A study finds a surprising response to cocaine in a novel strain of mutant mice — they failed to show hyperactivity seen in normal mice when given cocaine and didn’t run around. In other tests, they still found cocaine appealing, but displayed an inab…

Differences among brain neurons that coincide with psychiatric conditions

Scientists have found about 13,000 regions of epigenetic differences between neurons in different brain regions that vary by at least 10 percent. The location of those epigenetic changes — covering about 12 million bases in the genome — co-locate wit…

A new way by which the human brain marks time

With a little help from HBO’s ‘Curb Your Enthusiasm,’ neurobiologists have uncovered a key component of how the human brain marks time.
