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.
Perceived animacy decreases significantly as a function of exposure time for android faces.
When the expression of the ER-alpha gene was blocked in white-throated sparrows, the level of aggression they exhibited decreased.
A newborn's brain is more adult-like than previously assumed. Neuroimaging revealed much of the visual cortex scaffolding is in place, along with patterns of brain activity at 27 days of age, although it is not quite as strong as seen in adult brains.
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.
fMRI neuroimaging reveals the parietotemporal cortex of dogs responds to numeric concepts. The study provides evidence that numerosity is a shared evolutionary neural mechanism.
Twin study reveals higher cardiovascular health is associated with better cognitive health.
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.
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.
Advanced imaging techniques visualize macrophages in brain tumors in mouse models of glioblastoma.
A new deep learning algorithm can predict those at risk of psychosis with 93% accuracy by examining the latent semantic content of an individual's speech.
Computational model sheds light on the impact chronic, low-grade inflammation has on the mesolimbic dopamine system and motivational impairments.
