Neuroplasticity: Word and face recognition with half a brain

Neuroplasticity: Word and face recognition with half a brain

NeurobiologyNeuroscience

By César Tomé

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 […]

Magma may bubble below Mars’ surface A new study of quake data from Mars rover InSight suggests the red planet may experience underground volcanism. Characteristics of 20 quakes in the Cerberus Fossae region of the planet are consistent with movement generated in a warm subsurface locale.

Spintronic devices are based on the inherent spin magnetic moment of the electron, the same way electronic ones are on just its charge, to store and process information. These devices should, in theory, operate faster and at lower temperatures than their current electronic-only counterparts because an electron’s spin can be flipped much quicker than its […]

Fermentation is a form of anaerobic respiration occurring in certain microorganisms, like yeasts. Many processes arising in diverse contexts can be classified as fermentation processes, such as manufacturing of some food products (baking, wine and beer industries are based on them) and of some industrial and pharmaceutical chemicals. Alcoholic fermentation comprises a series of biochemical […]

Mutation found to affect circadian rhythm Researchers have discovered genetic mutations in hamsters that speed up the animals’ internal clock and affect circadian rhythms. “We suspect this might be relevant in understanding the effects of jet lag and shift work,” said neurobiologist Eric Bittman, a co-author of the study.

The band theory of metals has been experimentally tested many times and is now the accepted model of the behaviour of conductors and insulators. Electrical resistance is due to collisions of the electrons (whether treated as particles or waves) with impurities, imperfections, and especially the lattice vibrations of the metal crystal. The lattice vibrations of […]

Discarded electronic devices, such as cell phones, are a fast-growing source of waste. One way to mitigate the problem could be to use components that are made with renewable resources and that are easy to dispose of responsibly. Now, researchers have created disposable papertronics, a prototype circuit board that is made of a sheet of […]

In 1906, Alois Alzheimer, a psychiatrist and neuroanatomist, reported “a peculiar severe disease process of the cerebral cortex” to a gathering of psychiatrists in Tübingen, Germany. The case was a 50-year-old woman who suffered from memory loss, delusions, hallucinations, aggression and confusion – all of which worsened until her untimely death five years later. In […]

Black hole collision behaves as Einstein predicted Scientists studying the collision of two huge black holes observed massive gravitational waves and a phenomenon known as precession, which resembles the wobbling motion of a spinning top. Albert Einstein’s theory of general relativity predicted a century ago that precession would occur in massive objects — but this […]
