In a recent study of epilepsy patients and healthy volunteers, National Institutes of Health researchers found that our brains may withdraw some common words, like “pig,” “tank,” and “door,” much more often than…

Lab-grown Cells Offer New Opportunities To Study Hearing Loss

Hearing loss is the most common loss of sensation. Most cases of hearing loss are due to the death of specialized hair cells found deep inside the ear. These hair cells convert sounds into nerve impulses which can be understood by the brain. Hair cells naturally degrade as part of aging and can be damaged…

Gender Differences In Memory

Although there are many physiological and psychological gender differences in humans, memory, in general, is fairly stable across the sexes. By studying the specific instances in which males and females demonstrate differences in memory, we are able to further understand the brain structures and functions associated with memory. It is within specific experimental trials that…

Imaging The Brain’s Age With MRI Plus MEG

How old are you? What about your body, and your brain? People are used to answering this question by counting the years since birth. However, biological age could also be measured by looking at the integrity of the DNA in cells or by measuring the levels of proteins in the blood. Whether one goes by…

Genetic Malfunction Of Brain Astrocytes Triggers Migraine

A genetic dysfunction in specific brain cells strongly influences head pain occurrence, neuroscientists of the University of Zurich report1. This familial hemiplegic migraine type 2 (FHM2) causes a malfunction of astrocytes in the cingulate cortex, a brain region that is involved in the feeling of pain. Migraine is one of the most disabling neurological disorders,…

Aphantasia May Make Dreaming, Remembering, And Imagining Harder
