New research from King’s College London has found that MDMA, the main ingredient in ecstasy, causes people to cooperate better - but only with trustworthy people. In the first study to look in detail at how MDMA impacts cooperative behaviour the researchers also identified changes to activity in brain regions linked to social processing.

About 1% of patients diagnosed with autism spectrum disorder and intellectual disability have a mutation in a gene called SETD5. Scientists have now discovered what happens on a molecular level when the gene is mutated in mice, and how this changes the mice’s behavior.

Why do animals differ in personality? Researchers at Linköping University used human drugs that alter two brain chemicals, serotonin and dopamine, to see if these drugs would change the behavior of animals.

The cerebellum, a structure found in the back of the skull, is known to be important for the control of movement, while the frontal cortex is responsible for cognitive functions such as short-term memory and decision making. However, as researchers continue to unlock the mystery of how billions of neurons in the brain interact, it is becoming more apparent that it is not that black and white.
