In an unexpected twist in neuroscience dogma, the cells on the receiving end of neurotransmission appear to be able to release glutamate to regulate the transmitting cell’s activity.

Understanding how the brain coordinates electrical activity could be key to developing more-effective treatments for a variety of brain disorders.

The hormone, which is well known for regulating appetite, appears to influence neuronal development—a finding that could shed light on disorders such as autism that involve dysfunctional synapse formation.

Robert Froemke and Liisa Galea will discuss the neurological changes that occur during motherhood and their effect on behavior and brain health.

Mice and flies given the polyamine in their diet have increased brain cell metabolism and cognitive function, and epidemiological data hints at a similar benefit in humans.

A study that compared several anesthetic regimens in rodents showed that only one—inhaled isoflurane—wasn’t detrimental to the activity of neurons in the hippocampus.

Gamma delta T cells in the meninges of the brain release a cell signaling molecule that does more than protect mice from microbial pathogens.

People who show low social engagement over long periods of time often show reductions in cognitive function. Studies of the brain may provide clues about this correlation.

The activation of young brain cells in adult mice is necessary not just for forming memories, but consolidating them during rapid eye movement sleep, a study shows.

A new study in mice does not find evidence supporting two popular ideas for the mechanism for bridging the temporal time gap between two paired stimuli.

A fluorescent image of murine hippocampal cells is the winning microscopy image from more than 400 submissions from 65 countries for Olympus’s 2019 Image of the Year Award.

Memory formation in mice involves coordinated activity at the cellular level that likely leads to new circuits in the brain.

By trimming synapses in the adult mouse hippocampus, microglia help facilitate forgetting.

The silicon chips receive and send electrical signals, recreating activity from neurons in the rat brain that play a role in breathing and thinking.

New, unpublished results show some of the cells produce new neurons for up to 90 days, much longer than a previously identified set of neural stem cells that only generate neurons for a month or two.

Conflicting results on the existence of new neurons in adults have researchers designing new ways to identify and count neuronal progenitors—and finally get to the bottom of neurogenesis.

The Yale University cognitive neuroscientist studies how the brain extracts patterns from experiences.

Despite doubts last year about human adult neurogenesis, a study shows even 80-year-olds develop new cells in the hippocampus, but such growth is diminished in patients with Alzheimer’s disease.

A mouse study finds that when blood platelets are activated during exercise, they release factors that increase the number of newborn neurons in the hippocampus.
