Sequential hodology of three major inhibitory cell classes. All classes receive inputs from local ECs. Vip cells (a subclass of Htr3a interneurons) receive input from higher-order cortex, and inhibit primarily other interneuron classes. Sst cells inhibit Pvalb cells and the dendrites of ECs. Pvalb cells receive strong feedforward inputs from thalamus and lower-order cortex, and inhibit ECs perisomatically. Note that multiple additional interneuron classes exist, whose hodology is not yet fully established.
