I. Fundamentals

1. Information Processing in Modular Circuits Linking Basal Ganglia and Cerebral Cortex
James C. Houk

This chapter serves as an introduction to the theme of the entire book. Later chapters will expand upon the theory presented here.

There appear to be "large arrays" of similar circuits connecting reentrant thalamo-frontal loops with striatal spiny neurons. Each such circuit also has a branch passing through the pallidum. Houk presents the theory that dopamine-modulated spiny neurons in the striatum act as pattern recognizers sensitive to large numbers of cortical inputs. When a spiny neuron detects its pattern, it causes a momentary pause in an ongoing pallidal discharge, which turns on the connected reentrant thalamo-cortical loop. This constitutes a working memory of the detected pattern. A subloop passing through subthalamic areas can turn off the reentrant memory loop.

Three ways that an active thalamo-cortical reentrant loop could influence behavior are 1) by turning on a reentrant motor control loop via cortical connections to the motor strip area, 2) by controlling a pons-cerebellum pathway, or 3) by affecting other pattern detector striatal spiny neurons.
