Researchers uncover brain circuitry central to reward-seeking behavior

Scientists have found that as mice learn to associate a particular sound with a rewarding sugary drink, one set of prefrontal neurons becomes more active and promotes reward-seeking behavior while other prefrontal neurons are silenced, and those neuron…

Brain-machine interfaces: Bidirectional communication at last

A prosthetic limb controlled by brain activity can partially recover the lost motor function. Neuroscientists asked whether it was possible to transmit the missing sensation back to the brain by stimulating neural activity in the cortex. They discovere…

Itch neurons play a role in managing pain

There are neurons in your skin that are wired to sense itchy things. These neurons are separate from the ones that detect pain, and yet, chemical-induced itch is often accompanied by mild pain such as burning and stinging sensations. But when it comes …

Superfluid is now helping brain surgeons

A superfluid, which resembles brain tissue, makes ultrasound images easier to interpret during an operation. This will make it easier for surgeons to remove brain tumors more accurately, say researchers.

Precise inactivation of neural messenger receptor wipes out fear memory in mice

Research combines antibody precision with toxic oxygen burst to inactivate neural protein and temporarily abolish fear memory in mice.

Study points to treatment strategy for anorexia

New research conducted in adolescent rodents provides insights on the mechanisms behind anorexia nervosa and points to a potential treatment strategy.

Experts raise concern over US advice to screen all adults and all teens for depression

Recent advice on depression screening from the US Preventive Services Task Force (USPSTF) may lead to overtesting and overtreatment, according to some experts.

Women with mild heart blockage report poorer health, more anxiety and negativity than men

Women with mild blockage of coronary arteries report poorer health, more anxiety and a more negative outlook than men with the same condition, according to new research in the American Heart…

Drugs that alter inhibitory targets offer therapeutic strategies for autism, schizophrenia

Researchers recently discovered that an inhibitory brain receptor triggers synaptic pruning in adolescence. Drugs that selectively target these receptors, when administered during adolescence, can alter synapse number, with possible implications for th…

Drugs that alter inhibitory targets offer therapeutic strategies for Autism, Schizophrenia

Memories are formed at structures in the brain known as dendritic spines, which communicate with other brain cells through ‘synapses.’ Researchers recently discovered that an inhibitory brain receptor triggers synaptic pruning in adolescence. Now, a ne…
