Dissolving implantable device relieves pain without drugs

Researchers have developed a small, soft, flexible implant that relieves pain on demand and without the use of drugs. The first-of-its-kind device could provide a much-needed alternative to opioids and other highly addictive medications. It works by so…

Cosmological thinking meets neuroscience in new theory about brain connections

A collaboration between a former cosmologist and a computational neuroscientist generates a new way to identify essential connections between brain cells.

Electrical stimulation improves arm control in paralyzed monkeys

Pre-clinical experiments suggest that electrical stimulation of surviving nerves of the upper spinal cord damaged by severe injury will allow individuals with limited arm function to partially regain lost movement.

Study finds women have more brain changes after menopause

Women who have gone through menopause may have more of a brain biomarker called white matter hyperintensities than premenopausal women or men of the same age, according to a new study.

Exercise-induced central fatigue — low oxygen supply clouds judgment

Research on the effects of exercise in low-oxygen environments on the brain demonstrated that cognitive performance worsens when lower-than-usual amounts of oxygen are carried by the blood. Consequently, tissue in brain regions with less critical funct…

No more binge eating: Signal pathway in the brain that controls food intake discovered

Researchers have developed a novel approach to treating eating disorders. The scientists showed that a group of nerve cells in the hypothalamus (so-called AgRP, agouti-related peptide neurons) control the release of endogenous lysophospholipids, which …

Researchers uncover brain waves related to social behavior

Researchers have discovered electrical brain-wave patterns given off during social interactions in mice. They also observed that mice showing signs of stress, depression, or autism lacked these brain waves. The results reveal more about the mechanics u…

‘Brain bleeds’ in babies first year can lead to long-term sight problems, study finds

Severe ‘brain bleeds’ experienced by some babies in the first year following their birth can lead to long-term sight problems, researchers have found as part of a ten-year follow-up study.

The octopus’ brain and the human brain share the same ‘jumping genes’

The neural and cognitive complexity of the octopus could originate from a molecular analogy with the human brain, according to a new study. The research shows that the same ‘jumping genes’ are active both in the human brain and in the brain of two spec…

A new model sheds light on how we learn motor skills

Researchers have developed a mathematical model of motor learning that reflects the motor learning process in the human brain. Their findings suggest that motor exploration — that is, increased variability in movements — is important when learning a …
