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 […]

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. […]

Default Mode Network May Contain A Universal Code For Aesthetics

Using functional magnetic resonance imaging (fMRI) to monitor subjects’ brain activity as they were shown images of art, architecture or natural landscapes, researchers have found that in the visual parts of the brain, different types of images led to very different patterns of activity, even across images all judged by subjects to be aesthetically pleasing[1]. […]

Spatial Navigation In The Brain: A Question Of Scale

Just like our ancestors before us, humans must be able to navigate within both familiar and new environments, whether this involves driving to work or finding our way around a new city. Successful spatial navigation depends on many cognitive processes including memory, attention, and our perception of direction and distance[1]. A key issue, however, is […]

A Direct Link From The Brain’s Emotion Areas To The Motor Cortex

In high stress situations like making a goal in soccer, some athletes go through a quick slump in performance under pressure, known as “choking.” Now, Salk Institute researchers have uncovered what might be behind the phenomenon – one-way signals from the brain’s emotion circuit to the movement circuit. The research[1] could lead to new strategies […]
