neurotrophic factor refer to chemical mediators that
operate over different timescales
- (^) Neurotransmitters are released by presynaptic terminals and produce rapid excitatory or inhibitory responses in postsynaptic neurons
- (^) Neuromodulators are released by neurons and by
astrocytes, and produce slower pre- or postsynaptic
responses
- (^) Neurotrophic factors are released mainly by non-neuronal cells and act on tyrosine kinase-linked receptors that regulate gene expression and control neuronal growth and phenotypic characteristics
