Do pets make you happier? Study shows they didn’t during the pandemic

There is a general understanding that pets have a positive impact on one’s well-being. A new study found that although pet owners reported pets improving their lives, there was not a reliable association between pet ownership and well-being during the …

Physical fitness since childhood predicts cerebellar volume in adolescence

Physical fitness since childhood is associated with cerebellar grey matter volume in adolescents. Those who were stronger, faster and more agile, in other words, had better neuromuscular fitness since childhood, had larger Crus I grey matter volume in …

Brain imaging identifies biomarkers of mental illness

Research and treatment of psychiatric disorders are stymied by a lack of biomarkers — objective biological or physiological markers that can help diagnose, track, predict, and treat diseases. In a new study, researchers use a very large dataset to ide…

Human brain takes stock of blame

Researchers have found that the human brain can distinguish between an outcome caused by human error and one in which the person’s decision-making is blameless. The brain takes just one second to separate the outcomes, and in cases involving human erro…

A thyroxine derivative enhances brain drug delivery

A new study shows that the delivery of drugs into the brain, and especially into glial cells, can be enhanced with prodrugs that temporarily incorporate thyroxine or a thyroxine-like molecule.

Researchers identify brain network that is uniquely activated through injection vs. oral drug use

Results from a new clinical trial suggest that a group of brain regions known as the ‘salience network’ is activated after a drug is taken intravenously, but not when that same drug is taken orally. When drugs enter the brain quickly, such as through i…

Validating the role of inhibitory interneurons in memory

To expand the understanding of memory, a research team has developed a technology called LCD-eGRASP (local circuit dual-eGRASP) that can label synapses of neural circuits within a specific brain region. The team applied this new technology to identify …

Why we don’t all develop posttraumatic stress disorder after trauma

Researchers show why only a subset of individuals exposed to trauma develop posttraumatic stress disorder (PTSD). The research, centered on the body’s stress hormone response, could pave the way for more targeted treatments for PTSD.

When dads are feeling a bit depressed or anxious, how do kids fare?

A team of researchers has found that slightly higher, but mild anxious or depressive symptoms in fathers were associated with fewer behavioral difficulties in the first years of elementary school and better scores on a standardized IQ test in their chi…

Brain implant may enable communication from thoughts alone

A speech prosthetic developed by a collaborative team of neuroscientists, neurosurgeons and engineers can translate a person’s brain signals into what they’re trying to say. The new technology might one day help people unable to talk due to neurologic…
