Huperzine A, a compound that comes from a club moss, has been shown to increase resistance to induced seizures in mouse models of genetic epilepsy, a new study reports.

Those with dark personality traits such as psychopathy, sadism, low affective empathy, narcissism, cold-heartedness, and meanness, are more likely to sexually objectify those of the opposite sex.
Stimulating the cingulum bundle during neurosurgery where people are awake results in immediate laughter, followed by a sense of calm and happiness in patients, a new study reports.
Combining neuroimaging and a constructed virtual reality town, researchers found the brain uses three different systems to perceive environment. One system allows us to recognize a place, another helps navigate through that location, and the third helps navigate from one place to another. The parahippocampal place area (PPA) helps encode location recognition, while the retrosplenial complex allows for mentally mapping the locations of specific places.
When people hear screams of excited happiness, they tend to confuse the emotion with fear. Researchers say the bias toward categorizing excited and joyfully screams as fear has evolutionary roots.
fMRI neuroimaging reveals the parietotemporal cortex of dogs responds to numeric concepts. The study provides evidence that numerosity is a shared evolutionary neural mechanism.
When the expression of the ER-alpha gene was blocked in white-throated sparrows, the level of aggression they exhibited decreased.
