Synapse-specific plasticity governs the identity of overlapping memory traces

Each memory is stored in a specific population of neurons called engram cells. When a memory is linked with another to generate an associative memory, two memory traces overlap. At the same time, individual memories maintain their own identities. Using…

One step closer to finding a cure for brain diseases

Researchers have identified a mechanism for signaling brain nerve cells through excitatory synaptic binding proteins. The finding provides important clues to understanding the principles of synaptic nerve transmission and thus can be used to analyze th…

Can Lexapro cause weight changes?

Lexapro is the brand name for a drug called escitalopram, which treats depression and anxiety. As a side effect, Lexapro may cause some people to gain a small amount of weight. Less commonly, it may cause weight loss. A healthful diet and regular exerc…

OCD: Why living in a sunless region can increase symptoms

Obsessive-compulsive disorder symptoms are influenced by where a person lives and how much access they have to sunlight. Researchers explain why this may be.

Headers may cause balance issues

Soccer players who head the ball may be more likely to experience short-term balance problems, suggesting that repetitive head impacts could have the potential to cause subtle neurological deficits not previously known, according to a preliminary study.

Antioxidant benefits of sleep

Scientists found that short-sleeping fruit fly mutants shared the common defect of sensitivity to acute oxidative stress, and thus that sleep supports antioxidant processes.

Machine learning helps to predict the treatment outcomes of schizophrenia

Researchers have used artificial intelligence to help identify patients suffering from schizophrenia and to ascertain if they would respond to treatment.

Herpes linked to Alzheimer’s: Antivirals may help

A new commentary on a study by epidemiologists supports the viability of a potential way to reduce the risk of Alzheimer’s disease. When the authors looked at subjects who suffered severe herpes infection and who were treated aggressively with antivira…

Brain function partly replicated by nanomaterials

Researchers have created extremely dense, random SWNT/POM network molecular neuromorphic devices, generating spontaneous spikes similar to nerve impulses of neurons. They conducted simulation calculations of the random molecular network model complexed…

Why the left hemisphere of the brain understands language better than the right

Nerve cells in the brain region planum temporale have more synapses in the left hemisphere than in the right hemisphere — which is vital for rapid processing of auditory speech, according to new research. There has already been ample evidence of left …
