Noninvasive brain stimulation restores behavioral flexibility in cocaine-exposed rats

Noninvasive brain stimulation restores behavioral flexibility in cocaine-exposed rats
A major impediment to treatment of substance use disorder (SUD) is a loss of behavioral flexibility, whereby one s judgment is impaired such that their actions continuously result in negative consequences. Such decisions include continuing to use drugs, but this inflexibility extends to other areas of life and can continue even well into abstinence from drug use. Previous research in animals suggests that this inflexibility can be traced to reduced neural signaling in brain regions critical for behavioral flexibility.
Now, a new study led by Elizabeth West, PhD, and Regina Carelli, PhD, of the Carolina Center for Neurostimulation, University of North Carolina, Chapel Hill, NC, USA, shows that a noninvasive form of brain stimulation used in cocaine-exposed rats kick-started the brain activity and restored behavioral flexibility in the rodents. The paper appears in ....

Daily caffeine consumption can change the gray matter of the brain

Daily caffeine consumption can change the gray matter of the brain
Coffee, cola, or an energy drink: caffeine is the world s most widely consumed psychoactive substance. Researchers from the University of Basel have now shown that regular caffeine intake can change the gray matter of the brain. However, the effect appears to be temporary.

No question - caffeine helps most of us to feel more alert. However, it can disrupt our sleep if consumed in the evening. Sleep deprivation can, in turn, affect the gray matter of the brain, as previous studies have shown. So can regular caffeine consumption affect brain structure due to poor sleep? A research team led by Dr. Carolin Reichert and Professor Christian Cajochen of the University of Basel and UPK (the Psychiatric Hospital of the University of Basel) investigated this question in a study. ....

Brain Plasticity
Neuroplasticity, the remarkable ability of the brain to modify and reorganize itself, is affected by or in response to excessive alcohol, whether through individual consumption or exposure in the womb.
It is now well accepted that the birth and integration of new neurons continue beyond development and into adulthood. New discoveries and insights on how alcohol impacts this and other plastic processes are discussed in Alcohol and Neural Plasticity, a special issue of ....

Blood-Donation Barriers for Gay, Bisexual Men (VIDEO)

January 21, 2021
The FDA requires gay and bisexual men to abstain from sex for three months before giving, but some experts say that s based on outdated science.
SHOW TRANSCRIPT
There s a critical need for blood donation because of the pandemic, but a group of people is left out of the donation pool: gay and bisexual men.
It s incredibly frustrating. And frankly, I mean, just not even to tone it down, it pisses me off, says Dr. Greg Zahner, a resident physician at Massachusetts General Hospital.
He wrote We Need Blood and I Am Not Allowed to Help in the Journal of the American Medical Association. Zahner is gay and works in the front lines fighting COVID-19. Under FDA guidelines, men who have sex with men, or MSM, must abstain from sex for three months before giving blood. This restriction still applies to men in monogamous relationships. ....
