Theta EEG activity is observed during learning, especially

for movement directed tasks.  This EEG activity is generated by synchronized

synaptic oscillations and discharge activity among many thousands (possibly millions)

of midbrain, hippocampal and neocortical neurons subserving navigation, motor planning

and limbic system integration. 

The sensory/motor integration circuitry that drives theta EEG activity can be separated

into two ascending pathways: Type 1 and 2, distinguished by behaviour and drug sensitivity, based on different synaptic,

circuit and network properties associated with these two brain oscillation rhythms.
