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 …

Silence for thought: Special interneuron networks in the human brain

Scientists map prominent differences in the neural circuits of mice, monkeys, and human.

Researchers untangle the APOE4 gene, the most significant genetic risk factor for Alzheimer’s disease

Researchers have discovered two important novel aspects of the gene: 1) human genetic background inherited with APOE4 is unique to APOE4 patients and 2) the mechanistic defects due to APOE4 are unique to human cells.

Research reveals the pons plays a significant role in processing sad information

Researchers conducted studies to explain the neural mechanisms of the pons-corticolimbic network in perpetuating sad mood in depression.

Feelings of detachment predict worse mental health outcomes after trauma

Following trauma, feeling detached from one’s surroundings may suggest a higher risk of later developing serious mental health conditions. It’s important to screen for feeling detached to identify patients who might benefit from preventive care.
