Signals in your brain that tell you when It’s time to move

A new study examines how the brain initiates spontaneous actions. In addition to demonstrating how spontaneous action emerges without environmental input, this study has implications for the origins of slow ramping of neural activity before movement on…

Brain scanning approach shows wiring of depression

By repeatedly scanning the brains of a small group of patients for a year and a half, researchers have identified a distinct pattern of neuronal interactions that appears to predispose some people to developing depression.

A new role for intelligent tutors powered by AI in brain surgery?

Researchers are designing real-time, intelligent tutors powered by AI. These systems mimic human surgical instructors in brain surgical training. Intelligent tutors help the learner acquire excellent skills by continuously assessing hand movements duri…

Prescribing nature can improve happiness and reduce anxiety

Green Social Prescribing is the practice of supporting people with mental health needs to engage in nature-based activities. Referrals will typically come from GPs, community mental health teams, or social workers, but people can also self-refer. Socia…

Flexible tentacle electrodes precisely record brain activity

Researchers have developed ultra-flexible brain probes that accurately record brain activity without causing tissue damage. This opens up new avenues for the treatment of a range of neurological and neuropsychiatric disorders.

Music can reveal which areas of the brain are affected by aging

Researchers are using works by Johann Sebastian Bach, along with MEG and MRI scans, to investigate how the brain compensates for age-related changes.

Anesthesia overrides carbon dioxide in regulating cerebrospinal fluid flow

A study on the effects of commonly used anaesthetic and sedative drugs on cerebrospinal fluid flow and volume has uncovered findings regarding their impact on the brain’s vital glymphatic system. These findings may affect neuroanaesthesia practices.

Novel immunotherapy improves recovery from spinal cord injury

Researchers have designed, in mice, an approach to minimizing the damage from a spinal cord injury through the use of engineered immune cells. Mice given the treatment had improved recovery from injuries, demonstrating potential for developing the ther…

Epigenetic changes reprogram astrocytes into brain stem cells

Resting brain stem cells hardly differ from normal astrocytes, which support the nerve cells in the brain. How can almost identical cells perform such different functions? The key lies in the methylation of their genetic material, which endowes these s…

Can technology turn exercise pain into pleasure?

Most exercisers stop ‘exer-gaming’ when the program gets too tough or dull — could sensors that tune into a person’s emotional state reverse low adherence?
