Tracking depression

Serotonin in depression is highly relevant in diagnosis, treatment, and drug development. To better study this area, a team has now developed a fluorescent probe for imaging processes that is highly sensitive and selective toward serotonin.

Brain scans reveal that mindfulness meditation for pain is not a placebo

Brain scans reveal that mindfulness meditation engages different neural pathways compared to placebo, demonstrating that pain relief from mindfulness meditation is not the result of the placebo effect.

Researchers discover new insights into the neurobiological origins of ataxia

A study investigated the origin of ataxia in the brain of patients with stroke. A significant number of the stroke lesions in the patients were located outside the cerebellum.

Regulatory gene influences shape recognition in medaka fish

Medaka fish that lacked functional Hmgn2 genes were unable to distinguish between simple shapes, revealing a new function for the regulatory gene.

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.
