A new study reveals the complex architecture of a decision-making circuit in the brains of C. elegans that prompts them to forage for food or stop once a source has been found.
Hexadecanal, a molecule excreted by humans, found in abundance on the scalps of babies, sparks behavioral changes in adults who are exposed to it. In women, the molecule decreases connectivity in parts of the brain associated with social decision making, but increases connectivity in males.
Stem cells collected from the placentas of women who gave birth to healthy babies could reduce neuroinflammation and reduce brain injury in growth-restricted babies.
By mapping how neurons in the brain are organized and examining how they communicate with one another, researchers are gaining a clearer understanding of how normal brains work and what happens when dysfunction occurs.
Memory errors may indicate a way in which the human cognitive system is optimally running, researchers say.
Researchers describe how specific facial features distinguish a child's face from an adult's face. The findings may help new technologies to quickly determine if children are depicted in indecent images.
The sound of speech elicits similar neural responses and stimulates the same brain regions in humans, guinea pigs, and macaque monkeys.
Switching to a diet that includes more leafy greens, including spinach and kale, reduces inflammation and oxidative stress, and improved symptoms associated with chronic migraine.
A growing body of evidence suggests psychedelics including psilocybin and LSD show promise in providing lasting relief from symptoms for those suffering some mental health disorders. Researchers found DOI, a similar drug to LSD, reduced negative behavioral responses following fear triggers in mouse models of anxiety.
Specialized brain cells associated with the neural process of learning in songbirds bear a striking resemblance to neurons associated with the development of fine motor control in humans.
Amyloid-beta accumulation in the brain may contribute to deficits in circadian regulation of learning and memory during the early stages of Alzheimer's disease.
