Previously unappreciated neurotransmitter system in the brain discovered

Researchers have identified a novel neurotransmitter system in the brain. The system signals transmission of innate olfactory information to areas of the brain associated with emotional processing via the TAAR5 receptor. The findings could help in the development of new treatments for depression and schizophrenia.

Parkinson’s disease may start before birth

10% of patients diagnosed with Parkinson's disease are between the ages of 21 and 50. For those with young-onset Parkinson's disease, researchers report the foundations for the disease may have been apparent before they were born. The study also points to a drug, currently approved to treat precancerous skin growths, that has the potential to reduce elevated levels of alpha-synuclein.
