Study Helps to Settle Debate on Roles of REM and Non-REM Sleep in Visual Learning


During non-REM sleep, visual areas of the brain exhibit an excitation/inhibition balance indicative of increased plasticity. REM sleep appears to be essential for people to reap the benefits of the increased plasticity that occurs during NREM sleep.

Scientists Observe Learning Processes Online in the Brain


Repeatedly administered tactile simulation over a sustained period of time alters neural processing of the hand area in the brain. The observable changes over time illustrate neuroplasticity and shed new light on the process of learning. Source: Neuroscience News

How Playing the Drums Changes the Brain


People who play drums regularly for years differ from unmusical people in their brain structure and function. The results of a study by researchers from Bochum suggest that they have fewer, but thicker fibers in the main connecting tract between the two halves of the brain. In addition, their motor brain areas are organized more efficiently. Source: TechnologyWorks

World-first Artificial Neurons Created To Fight Chronic Diseases


Artificial neurons on silicon chips that behave just like the real thing have been invented by scientists – a first-of-its-kind achievement with enormous scope for medical devices to cure chronic diseases, such as heart failure, Alzheimer’s, and other diseases of neuronal degeneration. Critically the artificial neurons not only behave just like biological neurons but only need one billionth the power of a microprocessor, making them ideally suited for use in medical implants and other bio-electronic devices.

When damaged, the adult brain repairs itself by going back to the beginning


When adult brain cells are injured, they revert to an embryonic state, according to new findings published in the April 15, 2020 issue of Nature by researchers at University of California San Diego School of Medicine, with colleagues elsewhere. The scientists report that in their newly adopted immature state, the cells become capable of re-growing new connections that, under the right conditions, can help to restore lost function.

A gut-to-brain circuit drives sugar preference


Sweet tasting foods don’t only trigger the taste buds, they also switch on a neurological pathway that begins in the gut. In the intestines, signals of sugar ingestion travel to the brain, sparking an appetite for more sweet foods. However, this pathway only responds to sugars, not artificial sweeteners.

Men and women have equal spatial cognition skills


Despite popular belief, men are not better (or worse) than women at spatial cognition tasks. However, men and women approach mental rotational tasks in different ways. Source: Neuroscience News
