Scientists pinpoint the uncertainty of working memory

Oct 12, 2021 by

A paper published in the journal Neuron, the human brain regions that are responsible for working memory content are also used to gauge the quality (uncertainty) of memories. Their research shows how these neural responses allow us to act...

Words and sounds processed separately but simultaneously in brain...

Sep 28, 2021 by

Neuroscientists have discovered a new pathway in our brains that processes the sounds of language. The new research indicates that auditory and speech processing occur in parallel. This contradicts the theory that our brains process acoustic information and then...

Mental abilities can improve with age

Sep 23, 2021 by

New research published in Nature Human Behavior indicates that two key brain functions can improve in older people. Scientists found that the functions—which allow us to attend to new information and to focus on what’s important in a given...

Math ability predicted by neurotransmitter levels

Sep 7, 2021 by

Researchers have discovered that a person’s math ability might be linked to levels of two chemical messengers in the brain: glutamate and gamma-aminobutyric acid (GABA). Oddly enough, the correlations were reversed in adults (lower GABA and higher glutamate =...

Phone conversations may aid early detection of Alzheimer’s

Jul 29, 2021 by

Researchers used machine learning to develop models that use the acoustic features of a person’s conversations to identify whether they may have early Alzheimer’s. The models might eventually translate into smartphone apps or online solutions to help identify the...
