1977 paper on the first autism twin study
Autism is caused by poor parenting, particularly by 'frigid' mothers who reject their children. Such a statement would seem bizarre today. But 30 years ago parents, especially mothers, were blamed for their childrenʼs autism. But then in 1977, one study, published in the Journal of Child Psychology and Psychiatry, single-handedly turned the field around to recognize the importance of genetics.

Ketamine targets lateral habenula, setting off cascade of antidepressant effects
The drug’s affinity for overactive cells in the “anti-reward” region may help explain its rapid and long-lasting results.
