Roughly 10 percent of the U.S. population is afflicted with major depressive disorder at any given time, and up to 20 percent will exhibit MDD symptoms over their lifetimes. Yet despite its prevalence, methods to treat MDD often fall short for a not-insignificant portion of the population. Antidepressants — the standard of treatment — don’t work for 30 percent with MDD. When infused at a low dose ketamine shows remarkable efficacy as a rapidly acting antidepressant, with effects observed within hours even in patients who have been resistant to other antidepressant treatments. However, consistent infusions of ketamine are needed to…

Oliver Selfridge was an early pioneer of artificial intelligence, and in 1959 wrote a classic paper outlining a system by which simple units, each carrying out a specialised function, could be connected together to perform complex, cognitive tasks. This ‘pandemonium architecture‘ inspired research in neural networks, which in turn led to modern machine learning about which we hear so much these days. The Pandemonium model is best known through some fantastically characteristic illustrations by Leanne Hinton in Lindsey & Norman’s 1977 introductory psychology textbook ‘Human Information Processing’. Here’s one: One internet citizen described the illustrations as ‘an attempt to explain…
