The act of laughing at a joke is the result of a two-stage process in the brain, first detecting an incongruity before then resolving it with an expression of mirth. The brain actions involved in understanding humour differ between young boys and girls. These are the conclusions reached by a US-based scientist supported by the Swiss National Science Foundation.

The structure of the brain shows the way in which we process numbers. People either do this spatially or non-spatially. A study by Florian Krause from the Donders Institute in Nijmegen shows for the first time that these individual differences have a structural basis in the brain.

Pioneering research points to a promising avenue for the treatment of post-traumatic stress disorder (PTSD) utilising neurofeedback training to alter the plasticity of brain networks linked to the condition.

Perseverance is a quality that plays a large role in the success or failure of many pursuits. It has never been entirely clear why this trait seems more apparent in some people than others, but a new piece of research may at least help explain where it comes from.

A mechanism in the brain which controls tics in children with Tourette Syndrome (TS) has been discovered by scientists at The University of Nottingham.

Dyslexia may be caused by impaired connections between auditory and speech centers of the brain, according to a recent study published  in Science. The research could help to resolve conflicting theories about the root causes of the disorder, and lead to targeted interventions.
