memory

The sea slug has helped scientists in their quest to understand how neurons encode memories.

To support thousands of incoming connections, neurons use sophisticated transportation networks for delivering mRNA to faraway regions.

Researchers redefine the lost art of smelling illness using one woman’s exquisitely sensitive nose.

A gene essential for information storage in the brain engages an autoregulatory feedback loop to consolidate memory.

A study finds roflumilast can reverse sleep deprivation–induced amnesia in mice, hinting at pathways to treating memory loss in people.

The Boston University neuroscientist wants to take the edge off traumatic memories by manipulating how they’re processed in the brain.

Researchers caution that it’s too soon to recommend supplements based on the results of a new study.

Low-intensity electrical stimulation allows older adults to better recall a list of words for at least a month following the treatment, a study finds, providing further evidence for the debated idea that electrical stimulation can enhance cognitive performance.

Bottlenose dolphins can recall trivial details of a prior event to later solve a novel task, a study finds, suggesting these mammals are capable of episodic memory.

A growth factor found in the cerebrospinal fluid of young mice triggered the proliferation of myelin-making cells when injected into the brains of older mice.

Like in humans, the neurotransmitter appears to play a role in generating wanting-like behavior and, perhaps, happy memories in honeybees.

People who had cognitive functions depleted by noninvasive brain stimulation or a mentally demanding task could subconsciously recognize individual words in a made-up language more easily than controls, researchers find.

Research in mice and flies suggests that bacteriophages, including those found in dairy foods, may have an influence on an animals’ ability to learn and remember information.

His work bridged the gap between psychology and neurobiology.

A new study links a variant of the apolipoprotein E gene called APOE ε4 to better memory in older age, even in the presence of amyloid plaques—a possible explanation for the variant’s persistence despite its association with an increased risk of Alzheimer’s disease.

Neurons in the hippocampus store information on the timing of experiences in addition to their content, helping to mediate sequential memory recall, a new study shows.

Author Lauren Aguirre finds reasons for optimism in the fight against Alzheimer’s disease.

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.
