Modulation of septo-hippocampal theta activity by GABAA receptors (Hajos et al. 2004)

Theta frequency oscillation of the septo-hippocampal system has been considered as a prominent activity associated with cognitive function and affective processes.
...
In the present experiments we applied a combination of computational and physiological techniques to explore the functional role of GABAA receptors in theta oscillation.
...
In parallel to these experimental observations, a computational model has been constructed by implementing a septal GABA neuron model with a CA1 hippocampal model containing three types of neurons (including oriens and basket interneurons and pyramidal cells; latter modeled by multicompartmental techniques; for detailed model description with network parameters see online addendum: http://geza.kzoo.edu/theta).
This connectivity made the network capable of simulating the responses of the septo-hippocampal circuitry to the modulation of GABAA transmission, and the presently described computational model proved suitable to reveal several aspects of pharmacological modulation of GABAA receptors.
In addition, computational findings indicated different roles of distinctively located GABAA receptors in theta generation.
