Web11 apr. 2024 · Pyramidal neurons located within layer V of the medial prefrontal cortex drive cognitive circuits by integrating afferent signals and sending efferent projections to cortical and subcortical targets. This role is supported by cholinergic neurotransmission, which modulates pyramidal neuron excitability via postsynaptic nicotinic receptors. In neuroanatomy, a nucleus (plural form: nuclei) is a cluster of neurons in the central nervous system, located deep within the cerebral hemispheres and brainstem. The neurons in one nucleus usually have roughly similar connections and functions.
