How the brain solves problems

In trying to think of an introduction for this article it occurred to me that had I been inside an MRI, the screen would have showed several brain regions lighting up like Times Square as my mind was attempting to solve the problem. First, the prefrontal cortex, basal ganglia and thalamus would recognize that the blank page meant that there […]

Brain organoids mimic head size changes associated with type of autism

Variations in the 16p11.2 region of the genome are associated with autism spectrum disorder. While people with genetic deletions in this region have larger heads (macrocephaly) and people with genetic duplications have smaller heads (microcephaly), both variation types affect brain development and function. To study the effects of these variations and search for ways to minimize their impact, University of […]

Altered functional brain network connectivity associated with symptoms of post-traumatic stress in COVID-19 survivors

COVID-19 survivors report significantly higher symptoms of post-traumatic stress, and these symptoms are associated with changes to the brain’s connectivity, according to a study coauthored by Vince Calhoun, Distinguished Professor of Psychology at Georgia State University and director of the Center for Translational Research in Neuroimaging and Data Science (TReNDS). Although COVID-19 is primarily considered a respiratory disease, experts recognize […]

‘Feel good’ brain messenger can be willfully controlled, new study reveals

From the thrill of hearing an ice cream truck approaching to the spikes of pleasure while sipping a fine wine, the neurological messenger known as dopamine has been popularly described as the brain’s “feel good” chemical related to reward and pleasure. A ubiquitous neurotransmitter that carries signals between brain cells, dopamine, among its many functions, is involved in multiple aspects […]

New stroke rehabilitation pattern based on brain-computer interface and robot technology

Strokes, which occur when the blood supply to part of our brain is interrupted or reduced, are the leading cause of death and disability in the adult population. Among the patients who survive, 75% will experience difficulties carrying out daily activities independently and need long-term functional exercises and rehabilitation. But the outcomes using traditional rehabilitation equipment are poor. In addition, […]

Eating disorder behaviors modulate the brain's dopamine-related reward circuit response

Researchers have found that eating disorder behaviors, such as binge-eating, alter the brain's reward response process and food intake control circuitry, which can reinforce these behaviors. Understanding how eating disorder behaviors and neurobiology interact can shed light on why these disorders often become chronic and could aid in the future development of treatments. The study, published in JAMA Psychiatry, was […]

Mouse brain imaged from the microscopic to the macroscopic level

Researchers at the University of Chicago and the U.S. Department of Energy’s (DOE) Argonne National Laboratory have leveraged existing advanced X-ray microscopy techniques to bridge the gap between MRI (magnetic resonance imaging) and electron microscopy imaging, providing a viable pipeline for multiscale whole brain imaging within the same brain. The proof-of-concept demonstration involved imaging an entire mouse brain across five […]
