Activated the most when the reward is unexpected. This is how pure desire can move to chronic compulsivity: the orbitofrontal cortex is the bridge between the limbic system and prefrontal cortex. Persistence (9. 22: the pathways (like the pleasure pathway) are made up of neurons. The anatomy of a neuron = soma, dendrites, axon, terminal. This neuron is real as viewed through a microscope. Dendrites and soma receive chemical information from neighboring neuronal axons. The chemical information is converted to electrical currents. A major impulse is produced (called the action potential) and travels down the axon toward the terminal: nucleus in the soma (cell body). Dendrites are associated with receiving messages from other (cid:374)euro(cid:374)s. the ter(cid:373)i(cid:374)al deli(cid:448)ers the (cid:373)essage to the (cid:374)e(cid:454)t (cid:374)euro(cid:374)"s de(cid:374)drite.
