Researchers have identified a brain pathway between the ventrolateral prefrontal cortex and the inferior temporal cortex which enables primates to effortlessly identify objects in their field of vision. Read More
Researchers have deciphered two axes along which the human brain is organized. The axes are mainly determined by genetic factors. Read More
When the expression of the ER-alpha gene was blocked in white-throated sparrows, the level of aggression they exhibited decreased. Read More
The inferior temporal cortex is capable of performing tasks, such as distinguishing between real and nonsense words and picking out specific letters from words. Read More
High resolution imaging reveals the human cerebellum is 80% of the area of the cortex. The findings indicate this area of the brain likely grew larger as human behavior and cognition evolved. Read More
Primates with larger brains can solve much more complex tasks using their hands than smaller-brained primates. However, improved dexterity comes at a cost. In humans and other large-brained primates, it takes longer for infants to learn the simplest hand and finger movements than our smaller-brained counterparts. Read More
Genomic research finds those who inherited a special ion channel from Neanderthals experience more pain. Read More
Envy alters individual behavior and, consequently, a person's strategies in characteristic ways. As a result of changed behavior, two separate social classes arise. Read More
Study reveals the progesterone receptor gene evolved rapidly in humans, but there is no evidence to support this happened because the changes were advantageous to our species. Researchers report the evolutionary force of selection was so weak that the gene accumulated harmful mutations as it evolved in humans. Progesterone receptor genes are vital during pregnancy as it supplies developing cells the ability to create progesterone receptors. Read More
Studying auditory regions and brain pathways in humans, apes, and monkeys, researchers have identified a language pathway that interconnects the auditory cortex with frontal lobe regions. The language pathway in other primates suggests an evolutionary basis in auditory cognition and vocal communication. Read More
Endocranial imprints of Australopithecus afarensis revealed they had an ape-like brain organization. Evidence was also found of protracted brain growth, which suggests infants may have had a longer dependence on caregivers, just like humans. Read More
Evolution does select for loner behavior, at least in slime molds. Loners provide both an ecological and evolutionary way to diversify a genetic portfolio to ensure the survival of the social, collective behavior. Read More
