Why do we freeze when startled? New study points to serotonin

When fruit flies experience an unexpected change in its surroundings, serotonin produced in the ventral nerve cord slows the insect down. The findings may shed light on the neurobiological mechanisms of human startle response.

Exposure to environmental PCBs impairs brain function in mice

Polychlorinated biphenyls (PCBs), chemicals commonly used during the 20th century as flame retardants and in industrial products, disrupt the performance of astrocytes, leading to impaired function. Environmental exposure to PCBs could contribute to a range of neurodegenerative diseases.

Researchers discover potential therapy to treat detrimental effects of marijuana

Prenatal exposure to THC makes dopamine neurons hyperactive and increases the sensitivity to the behavioral effects of the compound during pre-adolescence. This may increase the risk of developing schizophrenia later in life. However, treatment with pregnenolone, a drug under clinical trials for ASD, cannabis use disorder, and schizophrenia, appears to correct the brain abnormalities and behavioral problems associated with prenatal cannabis exposure.

Molecular link between chronic pain and depression revealed

Inhibitory inputs to the neural circuit between the dorsolateral bed nucleus of the stria terminalis (dlBNST) to the ventral tegmental area (VTA) increase when a person is in chronic pain. This alteration is mediated by enhanced corticotropin-releasing factor signaling within the dlBNST, leading to suppression of the mesolimbic dopaminergic system. The result is depressive mood and anhedonia associated with chronic pain.
