The brain tissue is filled by cells, the living units that enable function; the extracellular matrix, the scaffold wherein cells organize; and the blood vessels, which transport metabolic fuels such as oxygen and nutrients to the brain. Among the brain cells, we find the neurons, highly specialized cells that transmit information; and the glial cells […]
In 1868, the famous, powerful and short French neurologist Jean-Martin Charcot, known as “the Napoleon of the Salpêtrière hospital”, described a new disease. He called it “sclerose en plaque” in reference to the numerous scars or sclerosis seen in the white matter of the brain and spinal cord. We now call it multiple sclerosis. Multiple […]
Men and women are different. It has been long known that pregnancy and motherhood alter women’s brains. What was so far not clear was what happens to the brains of fathers. Recent research has shown that having children rewires fathers’ brains as well. Mother’s brains change to adapt to the demands of their babies, that […]
Electrical stimulation of the spinal cord can help recover mobility in some paralysed patients. However, the mechanism underlying this partial recovery of function remains unknown. A recent human study has confirmed the involvement of a group of cells previously identified in mice, paving the way to targeted treatments. In a recently published study in Nature […]
Why some people get migraines while others don’t? New research indicates that it might be due to specific brain changes in migraine sufferers, particularly, in the centrum semiovale, a white matter region underneath the cerebral cortex. New data presented at the yearly meeting of the Radiological Society of North America points towards brain differences among […]
Our brains “time-stamp” the order of incoming sounds, allowing us to correctly process the words that we hear, shows a new study by a team of psychology and linguistics researchers . “To understand speech, your brain needs to accurately interpret both the speech sounds’ identity and the order that they were uttered to correctly recognize […]
An unprecedented study of brain plasticity and visual perception found that people who, as children, had undergone surgery removing half of their brain correctly recognized differences between pairs of words or faces more than 80% of the time. Considering the volume of removed brain tissue, the surprising accuracy highlights the brain’s neuroplasticity– and its limitations […]
Long disregarded as a party drug, loved by hippies and alternative thinkers, LSD has been recently demonstrated to be much more than that, being useful as an anti-depressive and in therapy against PTSD and other traumas. Now, another “power” of LSD has been uncovered: it potentiates brain plasticity, thereby improving memory and other cognitive processes […]
How to breed more intelligent humans? This is a difficult question, one which raises numerous issues, both ethical and scientific. Would you give your eyesight away to become brighter? As crazy as this question may sound, a blinding mutation might increase intelligence. The CORD7 (cone-rod dystrophy 7) mutation of the RIMS1 gene produces progressive blindness […]
For a long time, it was thought that dreaming occurred in the rapid eye movement phase of sleep (REM sleep). It is now well established that it can occur at any stage of sleep and, therefore, is not exclusive to a specific global vigilance state. Today, there is no known physiological correlate of a dream […]
