A chemical equation expresses the net change in composition associated with a chemical reaction by showing the number of moles of reactants and products. But because each component has its own molar mass, equations also implicitly define the way in which the masses of products and reactants are related.
Comment in Cell. 2011 Sep 2;146(5):675-7. Basal synaptic transmission involves the release of neurotransmitters at individual synapses in response to a single action potential. Recent discoveries show that astrocytes modulate the activity of neuronal networks upon sustained and intense synaptic activity.strocytes are endogenous regulators of basal transmission at central synapses.

The nucleus basalis magnocellularis (aka Nucleus Basalis of Meynert (' NBM)) is a nucleus in the basal ganglia. This is a group of cholinergic neurons in the substantia innominata of the basal forebrain which has wide projections to the neocortex and is rich in acetylcholine and choline acetyltransferase.n Parkinson and Alzheimer diseases the nucleus undergoes degeneration. A decrease in acetylcholine production is seen in Alzheimer's disease, Lewy body dementia and some Parkinson disease patients showing abnormal brain function, leading to a general decrease of mental capacity and learning.
