Researchers have identified a neural network in the brains of monkeys that may represent a common evolutionary origin for social communication and human speech.
Working memory isn't confined to one area of the brain. It requires synchronous activity of at least two brain areas.
The posterior inferotemporal cortex plays a critical role in attention. Researchers say the discovery may require rethinking old concepts of attentional control.
Researchers suggest that when in a group, ants behave in a similar fashion to networks of neurons in the brain.
A new study of ant populations reveals group living confers immediate benefits, even among genetically identical individuals. The study revealed larger groups produced more offspring and greater stability than smaller groups. The study may shed new light on the evolution of social behavior.
Sensory neurons that send signals from the intestines to the brain stem extend to the interface of areas of the intestine that are exposed to high levels of microbial compounds. Turning off the neurons, researchers observed activated neurons in the brainstem as well as activation of gut neurons that control intestinal motility. The findings shed light on the potential mechanisms behind neurological abnormalities and intestinal diseases, including IBS.
Researchers have identified specific anti-bodies that can have a neutralizing effect on the virus responsible for tick-borne encephalitis. Preliminary response in using the anti-bodies in mice has proven affected in preventing TBE. It is hoped a vaccine candidate for TBE can be developed for humans.
Researchers have identified specific chemical changes in the brain that drive nicotine addiction. The findings could lead to new treatments to help break the addiction.
Researchers report a plasma component that is usually involved in blood clotting and inflammation may also play a role in the development of Alzheimer's disease.
Mice with the Alzheimer's disease-associated APOE4 and the APOE2 genes were more likely to die from COVID-19 than those with the APOE3 gene. Those with APOE4 and APOE2 genes had more virus replication in the lungs, higher inflammation, and increased tissue damage following coronavirus infection.
Study reveals dopamine neurons that play a role in learning and memory also drive motivation.
A new study could offer insight into human glial cell function and reveals a relationship between movement and sleep.
