Daytime Brain Activity Strength Drives Need For Sleep

The intensity of brain activity during the day, regardless of how long we’ve been awake, appears to escalate our requirements for sleep, according to a new University College London study in zebrafish. The research found a gene that responds to brain activity in order to coordinate the need for sleep. It helps shed new light […]

mesoSPIMs – New Microscopes Untangle the Enigmas Of Brain Organization

Advanced new microscopes, called mesoSPIMs, are able to image the meticulous detail of brain tissue, down to individual neurons five times thinner than a human hair, and can uncover the 3D anatomy of entire small organs, quicker than ever before. MesoSPIMs enable new insights into brain and spinal cord organization for researchers working to restore […]

Genetic Regions Associated With Left-Handedness Identified

For the first time, a study has pinpointed regions of the genome associated with left-handedness in the general population, and linked their effects with brain architecture. The study[1], led by researchers at the University of Oxford, linked these genetic differences with the connections between areas of the brain related to language. It was already known […]

Heroin Reduces The Brain’s Ability To Form Synapses

Exposure to heroin sharply reduces levels of the protein necessary for developing and maintaining the brain’s synapses, a preclinical study[1] by University at Buffalo researchers has found. The development of addiction relapse is directly related to the impact that reductions in this protein, called drebrin, have on specific cells involved in the brain’s pleasure-seeking/reward pathways.
