A new class of painkillers that block a receptor called TRPV1 may interfere with brain functions such as learning and memory, a new study suggests. The experiments with rat brain found that the TRPV1 receptor regulates a neural mechanism called long-term depression, which is believed to be central to establishing memory pathways in the brain. The researchers said their findings also suggest that the function of TRPV1 in neural tissue may explain reported side effects of the drug Acomplia. (source: sciencedaily.com)
