Neurological diseases including Parkinson’s, Tourette’s, attention deficit hyperactivity disorder, Alzheimer’s and schizophrenia are all associated with alterations in dopamine-driven function involving the dopamine transporter (DAT). Researchers suggest that a number of estrogens acting through their receptors affect the DAT, which may explain trends in timing of women’s susceptibility to these diseases.

General intelligence varies among primates within a single species, according to new research. The study is the first to look at general intelligence within one primate species. Through a series of cognitive tests, the researchers were able to divide the monkeys into high, middle and low performing groups. The findings may help us to understand [...]
