Breaking through the blood-brain barrier The bacteria that sneak past the brain's defenses to cause deadly bacterial meningitis are clever adversaries. New research investigates the molecular tricks bacteria use to convince their host that they are harmless and cause disease.
Brain protein linked to binge-drinking behavior Scientists have discovered that a brain protein has a key role in controlling binge drinking in animal models. According to the U.S. Centers for Disease Control and Prevention, binge drinking -- defined as drinking to the point of intoxication -- puts people at greater risk for health problems such as cardiovascular disease, liver disease and neurological damage.

School segregation still impacts African-Americans’ minds decades later As the nation observes the May 17 anniversary of the Supreme Court decision that ended racial segregation in public schools, a new study has found that desegregated schooling is tied to better performance for certain cognitive abilities in older African American Adults. This research is published in an article titled “Education Desegregation and Cognitive Change [...] The post School segregation still impacts African-Americans’ minds decades later appeared first on PsyPost.
Scientists link brain protein to binge-drinking behavior Scientists at The Scripps Research Institute (TSRI) have discovered that a brain protein has a key role in controlling binge drinking in animal models. They found that deleting the gene for this protein in mice ramped up alcohol consumption and prevented the brain from signaling the rewarding properties of alcohol. “Alcohol hits a lot of [...] The post Scientists link brain protein to binge-drinking behavior appeared first on PsyPost.
An important step in artificial intelligence In what marks a significant step forward for artificial intelligence, researchers at UC Santa Barbara have demonstrated the functionality of a simple artificial neural circuit. For the first time, a circuit of about 100 artificial synapses was proved to perform a simple version of a typical human task: image classification. “It’s a small, but important [...] The post An important step in artificial intelligence appeared first on PsyPost.
Researchers investigate an enzyme important for nervous system health Scientists from The Scripps Research Institute (TSRI), working closely with researchers at the National Institutes of Health (NIH), have mapped out the structure of an important protein involved in cellular function and nervous system development. The new structure provides crucial information for understanding how the protein binds to cellular components. It’s also the first structure [...] The post Researchers investigate an enzyme important for nervous system health appeared first on PsyPost.
April (and May, and Probably June) Is the Cruelest Month Depression and even suicidal behavior increase in spring. But why?
Brain cells capable of 'early-career' switch A single molecule has been identified that controls the fate of mature sensory neurons, scientists report. By studying sensory neurons in mice, the team found that the malfunction of a single molecule can prompt the neuron to make an "early-career" switch, changing a neuron originally destined to process sound or touch, for example, to instead process vision.
Research Explores Meditation As Pain Therapy Including migraines and mild cognitive impairment, researchers at Wake Forest Baptist Medical Center are looking into the effectiveness of meditation and its ability to reduce pain. The study started because … ...

Why Some People Don’t Trust Others Have you ever wondered why some people can’t trust?  Maybe they are a client, a spouse, or a friend. Despite positive efforts of encouragement, they still struggle with being able … ...
Surprise: Facebook Says that Facebook A-Okay for News! A study was published last week in the journal Science that shows that Facebook’s algorithm isn’t the cause of a hypothetical “filter bubble” — where people see only news stories that align with their political leanings on a social network. The only problem? It’s a … ...
How Early Childhood Trauma Affects Adult Mental Health: 1... It doesn’t come as a surprise that the early childhood experiences of trauma will affect adult mental health later in life. And yet, somehow, many people continue to rely primarily … ...
New research implicates immune system in Rett syndrome The immune system plays an unsuspected and surprising role in the progression of Rett syndrome, a severe neurological disorder affecting children, new research suggests. Rett syndrome is a neurodevelopmental disorder that is caused primarily by mutations in the gene encoding for MeCP2, an important epigenetic regulator. Children with the disorder appear to develop normally but begin to lose acquired cognitive and motor skills at 6 to 18 months of age as symptoms start to show. As they age, patients are unable to acquire verbal skills and suffer from lack of motor control.
Researchers discover how cocaine, amphetamines disrupt the brain's normal functioning In a major advance in the field of neuropsychiatry, researchers have illuminated how cocaine and amphetamines disrupt the normal functioning of the dopamine transporter in the brain. This discovery paves the way for developing treatments that could blunt the effects of cocaine and amphetamines in patients who are addicted.
Study sheds new light on low-light vision, could aid people with retinal deficits Driving down a dimly lit road at midnight can tax even those with 20/20 vision, but according to a recent study, the brain processes the experience no differently than if it were noon. The same study also reveals how quickly the brain adapts to vision loss, contradicting earlier research and opening the door to novel treatments.
