Analysis of medicinal cannabinoids and their impact on six mental health disorders -- combining 83 studies including 3,000 people -- suggests that the use of cannabinoids for mental health conditions cannot be justified based on the current evidence.


The brain tunes itself to a point where it is as excitable as it can be without tipping into disorder, suggests a new study in rats. This criticality hypothesis asserts that the brain is poised on the fine line between quiescence and chaos. At exactly this line, information processing is maximized.


Rebellious music genres such as rap, punk and heavy metal do not appear to be linked to maladaptive personality traits, but conservative music such as country and gospel were weakly linked to traits that capture neurotic, hostile, and eccentric tendencies.
