Thiamine derivatives, especially TTFD, have long been used to support energy, with recent studies suggesting they may enhance brain function. In rats, TTFD administration increased dopamine levels in the medial prefrontal cortex.

Researchers have visualized in real-time how ATP levels change in neurons during spreading depolarizations, which occur after a stroke.

Ohio State researchers found sex-specific gene differences in the sinoatrial node, the heart’s natural pacemaker. Women’s genes promote faster heartbeats, while men’s gene activity favors inflammation and fibrosis, increasing arrhythmia risk.

Researchers have uncovered the molecular mechanisms that cause a commonly prescribed antipsychotic drug to produce harmful side effects similar to Parkinson’s disease symptoms.

Researchers tested artificial intelligence tools, using recordings from an electrocardiogram and a digital stethoscope, to find unknown heart problems in women of childbearing age seen in primary care.

Researchers developed a decoder that uses brain waves to cue movement in the lower leg in volunteers, demonstrating its potential for spinal cord injury rehabilitation. The study explores noninvasive spinal cord stimulation.

Researchers discovered that serotonin neurons in the brain are not independent but interact in complex ways to influence decision-making. Their findings show serotonin's role in guiding binary decisions, impacting behaviors associated with disorders.

In French Polynesia, scientists observed a previously undocumented, rapidly delivered but usually non-lethal type of shark bite in response to human aggression.

Researchers propose that mind blanking, characterized by a lack of mental content, is a distinct cognitive state. Unlike mind wandering, which involves active thought flow, mind blanking features reduced brain activity and physiological changes.

A study reveals unique brain activity during lucid dreaming. Using EEG data, the research identifies reduced beta-band power and increased gamma-band activity in specific brain regions.
