PET imaging of adult neurogenesis may contribute to better diagnosis of depression, evaluation of drug therapy effectiveness

A new non-invasive PET scanning technique has been used by researchers to obtain images of neuron proliferation in the subventricular zone and subgranular zone of the hippocampal dentate gyrus. Neurogenesis in the hippocampal dentate gyrus is known to …

Combat exposure may jeopardize the behavioral health of women in the military

In a recent study, combat exposure among Army enlisted women was associated with an increased likelihood of developing behavioral health problems post-deployment, including post-traumatic stress disorder (PTSD), depression, and at-risk drinking.

Sexual behavior: Millennials not the ‘hookup generation’ after all

While there is widespread notion that millennials are the ‘hookup’ generation through dating apps like Tinder, new research shows this is not the case.

Exercise results in larger brain size and lowered dementia risk

Regular physical activity for older adults could lead to higher brain volumes and a reduced risk for developing dementia. It particularly affected the size of the hippocampus, which controls short-term memory, and its protective effect against dementia…

Trading changes how brain processes selling decisions

Experience in trading changes how the human brain evaluates the sale of goods, muting an economic bias known as the endowment effect in which people demand a higher price to sell a good than they’re willing to pay for it. The findings come from a set o…

Researchers image brain cells’ reactions to concussive trauma

Using a laboratory device that can deliver concussive impacts to cell cultures and image the aftermath in real time, researchers are gaining new insight into how brain cells react to trauma.

Genetic associations for major depressive disorder

The discovery of 15 regions of the genome associated with major depressive disorder (MDD) in individuals of European descent is reported in a study published online this week in Nature Genetics.

Leaky calcium triggers brainstem blackout that results in sudden cardiac death

Researchers report how a mutation in a gene involved in the regulation of calcium inside brain cells can help trigger blackouts of the brainstem, the center that controls heartbeat and breathing, and increase the risk of sudden unexpected death.

Depression: 15 genomic regions linked with diagnosis

Researchers have located 15 genomic regions that are associated with depression. Several of these sites are near genes involved in brain development.

Mechanistic finding may help develop treatment for Ice Bucket Challenge disease

Motor neuron diseases rob patients of their ability to walk, eat, talk or breathe since they affect the motor neurons controlling the muscles. Young patients with spinal muscular atrophy (SMA) have a shortage of the survival motor neuron protein. Revea…
