Face pareidolia, the phenomenon of seeing facelike structures in inanimate objects, is a perceptual phenomenon that occurs when sensory input is processed by visual mechanisms that have evolved to extract social content from human faces.
Depending on the network state, certain neurons in the primary somatosensory cortex can be more or less excitable, which shapes stimulus processing in the brain.
A new study reveals the effects of a night binge drinking may last a little longer than we think. Researchers report cognitive impairments, memory deficits and problems with psychomotor skills are still present the day after, when there is little to no alcohol left in the blood stream.
Researchers say a new retinal imaging test could be a reliable tool for measuring the progression of neurodegenerative diseases, such as Alzheimer's. The study reports the tool can detect drusen, which is often higher in those with AD.
A person with a wider face was considered to be more dominant and possess stronger leadership skills than a person with a narrower face. This was especially true of males, who were also considered to be more electable when they had a wider face. Conservatives showed more bias toward women's faces and were less likely to vote for a woman because, despite having wider faces, they perceived the candidate as less dominant. Liberals were more likely to vote for a woman but, as with conservatives, they perceived a woman with a wider face to be less dominant than a male.
Norepinephrine facilitates fear processing by stimulating a population of inhibitory neurons in the amygdala, generating repetitive bursting patterns of electrical activity. This activity changes the frequency of oscillations in the amygdala from resting state to aroused state, promoting the formation of fear memories.
Dopamine neurons are activated less than in adults brains when teens are faced with the prospect of a reward, a new study reports.
Scientists have laid bare a novel molecular mechanism responsible for the major depression symptom, anhedonia, the loss of the ability to experience pleasure. The brain circuit involved in this newly elucidated pathway is largely identical between rodents and humans, upping the odds that the findings point toward new therapies for depression and other disorders. Additionally, opinion leaders hailed the study’s inventive methodology, saying it may offer a much sounder approach to testing new antidepressants.
