How does heightened attention improve our mental capacity? This is the question tackled by new research published in the journal Cell Reports, which reveals a chemical signal released across the brain in response to attention demanding or arousing situations. The discoveries indicate how current drugs in the treatment of Alzheimer’s, designed to boost this chemical signal, counter symptoms of dementia. The results could also lead to new ways of enhancing cognitive function to counteract Alzheimer’s and schizophrenia, as well as enhancing memory in healthy people.
