In visual working memory, the brain immediately transfers the memory of object shifts by re-encoding the memory among neurons in the opposite brain hemisphere.
Cortical-asymmetry loss begins when we hit our thirties, with an accelerated decline as we enter our sixties. The brain changes are further accelerated in those with Alzheimer's disease.
Epigenetic regulation controls whether certain genes on each side of the brain are switched on or off. The findings shed light on why Parkinson's disease often affects one side of the body before the other.
Researchers shed light on the neural mechanisms behind risk taking behaviors. The study reveals the decision to 'up the ante', even when faced with long odds, is a result of an internal bias that adds up over time and involves a 'push pull' dynamic between the two hemispheres of the brain.
