Daily release of glucocorticoids depends on coordination between the clock gene and activity rhythms of neurons within two parts of the hypothalamus.
A new algorithm uses neuroimaging data of amyloid levels in the brain and takes into account a person's age to determine when a person with genetic Alzheimer's risk factors, and with no signs of cognitive decline, will develop the disease.
Differences in cognitive control appear to be a matter of degree in healthy individuals.
Researchers have identified a new reward system in the brain. The study found long-range GABA neurons from the ventral tegmental area to the ventral nucleus accumbens shell are engaged in reward and reinforcement behaviors. This GABAergic projection inhibits cholinergic interneurons.
Neurons in the visual cortex change their response to the same stimuli over time.
Chikungunya, and other mosquito-borne alphaviruses are known to trigger brain infections and arthritis in those who contract the infections. Researchers have identified two antibodies that protect animals from diseases caused by alphaviruses. The findings could pave the way to new treatments and a universal vaccine for alphaviruses.
A new study reports a strong association between high levels of physical activity and the ability to maintain cognitive function in breast cancer patients who received chemotherapy.
A study spanning 17 years has found children born and raised in poverty had smaller subcortical brain regions, including the hippocampus, caudate, putamen, and thalamus. These brain areas also showed less growth over time.
Gantenerumab, an investigational drug for Alzheimer's disease, reduced amyloid plaques and lowered tau levels in the brains of people with genetic risk factors for the neurodegenerative disorder.
Findings from a mouse study reveal specific cells and proteins that control the sneeze reflex.
Immune cells in the meninges come from bone marrow in the skull and migrate to the brain through special channels without passing through the blood. These immune cells help to guard the brain and spinal cord against inflammation and infection.
Neural activity plays an underappreciated role in the development and growth of nervous system cancers, a new study reports.
