Team demonstrates miniature brain stimulator in humans

Engineers have developed the smallest implantable brain stimulator demonstrated in a human patient that could revolutionize treatment for drug-resistant depression and other psychiatric or neurological disorders.

Two key brain systems are central to psychosis

When the brain has trouble filtering incoming information and predicting what’s likely to happen, psychosis can result, research shows.

Study finds increased anxiety and PTSD among people who remained in Ukraine

Researchers conducted a survey to understand how the mental health of displaced Ukrainians has been affected by the ongoing war. Their findings describe high levels of post-traumatic stress disorder (PTSD) and generalized anxiety among both refugees an…

Brainless memory makes the spinal cord smarter than previously thought

Researchers have discovered the neural circuitry in the spinal cord that allows brain-independent motor learning. The study found two critical groups of spinal cord neurons, one necessary for new adaptive learning, and another for recalling adaptations…

Study helps explain why childhood maltreatment continues to impact on mental and physical health into adulthood

Childhood maltreatment can continue to have an impact long into adulthood because of how it effects an individual’s risk of poor physical health and traumatic experiences many years later, a new study has found.

Parkinson’s Disease: New theory on the disease’s origins and spread

New hypothesis paper builds on a growing scientific consensus that Parkinson’s disease route to the brain starts in either the nose or the gut and proposes that environmental toxicants are the likely source.

New origin of deep brain waves discovered

Biomedical engineering researchers have uncovered a previously unknown source of two key brain waves crucial for deep sleep: slow waves and sleep spindles. Traditionally believed to originate from one brain circuit linking the thalamus and cortex, the …

Researchers discover how we perceive bitter taste

A new study reveals the detailed protein structure of the TAS2R14, a bitter taste receptor that allows us to perceive bitter taste. In addition to solving the structure of this taste receptor, the researchers were also able to determine where bitter-ta…

Brain stimulation treatment may improve depression, anxiety in older adults

A noninvasive brain stimulation treatment improved depression and anxiety symptoms among older adults in a new study.

Connecting lab-grown brain cells provides insight into how our own brains work

Researchers have developed a technique to connect lab-grown neural ‘organoids’ (three-dimensional developmental brain-like structures grown from human stem cells) using axonal bundles, similar to the connections between regions in the human brain. This…
