... When NTs (such as ACh) are released graded potentials, not action potentials, are created on dendrites and neuron cell bodies. These graded potentials may be: 1. EPSPs (excitatory postsynaptic potentials) - the RMP shifts closer to threshold 2. IPSPs (inhibitory postsynaptic potentials) - the RMP ...

Molecular neuroscience
Molecular neuroscience is a branch of neuroscience that observes concepts in molecular biology applied to the nervous systems of animals. The scope of this subject primarily pertains to a reductionist view of neuroscience, considering topics such as molecular neuroanatomy, mechanisms of molecular signaling in the nervous system, the effects of genetics on neuronal development, and the molecular basis for neuroplasticity and neurodegenerative diseases. As with molecular biology, molecular neuroscience is a relatively new field that is considerably dynamic.
