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.
Researchers say dehumanization seems to be at the core of schadenfreude, the sense of pleasure at other peoples' misfortune.
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.
Listeners can correctly identify whether pairs of screams originate from the same person or two different people. Findings suggest human screams convey a level of individual identity and shed new light on their evolutionary origin.
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.
Researchers have implicated an enzyme that appears to make both Tau and alpha synculein more toxic in Alzheimer's and Parkinson's disease. Inhibiting this enzyme has already proved helpful in treating animal models of Alzheimer's disease. The researchers report they are moving on to testing drugs that inhibit AEP in animal models of Parkinson's disease.
Researchers identify a new mechanism that contributes to learning an association between a warning noise and a fearful event.
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.
