Term: projecting star neuron

Definition: The soma of a PSN is rounded or polygonal, measuring 20 to 23 micrometers, with a smooth, convex profile. These neurons send out three to seven primary dendrites that diverge radially (Fig. 12A, neurons b and c). Most frequently, primary dendrites ramify shortly after leaving the soma ( smaller than 35 micrometers), issuing long, usually terminal branches.
