Endocrine communication
a chemical is released into the bloodstream to act on a target tissue
Neurocrine (Synaptic) communication
chemical release and diffusion across a synapse
Autocrine communication
the chemical acts on the releasing cell
" Negative feedback-reduces subsequent release of the chemical
" Positive feedback-enhances subsequent release of the chemical
Paracrine communication
chemical diffuses to nearby target cells
Pheromone Communication

Allomone Communication
are chemicals released by one species to affect the behavior of another species
Neurogenesis
mitotic production of neurons form nonneuronal cells
Cell migration
movement of cells to establish distinct populations
Differentiation
precursor cells develop into distinctive neurons or glial cells
Synaptogenesis
