A study of combo jellies reveals the type of messenger that likely functioned in the ancestral nervous system.
Researchers identified 33 metabolic compounds in blood samples that differed between those with dementia and cognitively healthy older adults. 7 of the metabolites were elevated in dementia patients, while 26 were at lower levels compared to samples of those without dementia. Elevating levels of those metabolites could have a neuroprotective effect against dementia.
Combining machine learning with MRI brain scans helps researchers provide a more accurate map of the brain.
A new study reveals specific brain regions that individually promote patience through the action of serotonin.
Researchers identify three populations of neurons in layer 6 of the cortex that contribute to alertness.
Methylphenidate may boost norepinephrine levels in the prefrontal cortex, which in turn regulates dopaminergic neurons firing in the striatum, when a reward is delivered. The study sheds new light on how medications for ADHD affect the reward system in the brain.
Researchers have pinpointed how brain activity changes in mouse models of Parkinson's disease, providing clues as to what may drive symptoms of the disease in humans.
