“They found that older mice had nearly 40 percent fewer hypocretin-producing neurons than younger mice. The remaining neurons, which were more excitable than those present in younger mice, triggered wakefulness and poor sleep.”

“Molecular mechanisms involved in an antidepressant effect from exercise Many of these mechanistic studies point to the mood-enhancing activities of a few molecules: kynurenine, a compound produced during the conversion of the amino acid tryptophan to the vitamin niacin; brain-derived neurotrophic factor, or BDNF…”

“Repeated activation of SF1 neurons during recovery may create plasticity, the brain's ability to strengthen circuits through experience. These changes may let the brain keep a kind of record of past workouts and influence metabolic responses during future workouts.”

“The aggregation of a protein called alpha-synuclein is thought to play a role in the death of dopaminergic neurons in Parkinson's disease. In a new study, T-cells from patients with Parkinson's mounted an immune response against a protein alpha-synuclein whereas immune cells from people without Parkinson's did not.”

“Claflin, Kristin E., et al. "Pharmacological FGF21 signals to glutamatergic neurons to enhance leptin action and lower body weight during obesity."Molecular metabolism 64 (2022): 101564. Morville, Thomas et al.”

“FTA: > Researchers have discovered that stem cells taken from teeth can grow to resemble brain cells, suggesting they could one day be used in the brain as a therapy for stroke.”

“FTA: > Scientists report they can crank up insect aggression simply by interfering with a basic metabolic pathway in the insect brain. Their study, of fruit flies and honey bees, shows a direct, causal link between brain metabolism -- how the brain generates the energy it needs to function -- and aggression.”

“Researchers have investigated the effect of lipids bearing polyunsaturated chains when they are integrated into cell membranes. Their work shows that the presence of these lipids makes the membranes more malleable and therefore more sensitive to deformation and fission by proteins.”

“Amyloid beta plaques accumulate outside of neurons and disrupt synapses, which are the connections between neurons that are formed and allow neurons to communicate with each other.”

“The researchers give mice large doses of alcohol and found that it activated neurons (called AGRP). These are the neurons that are activated when the body experiences starvation.”
