Biological neural network models typically consist of excitatory and inhibitory neural populations, but do not distinguish various subtypes of inhibitory cells. The development of optogenetics enabled studying electrophysiological properties of inhibitory subpopulations, opening the possibility to investigate their effect on the dynamics of the entire network. A mean-field model of the primary visual cortex [1] was used to describe the effect of inhibitory subpopulations on spectral properties of population activity, but detailed understanding of the underlying dynamical system is still lacking. The goal of this thesis is to investigate linearized stability of stationary solutions in a simplified version of the model [1] in the presence of two inhibitory subtypes and compare it to the situation when one of the populations is optogenetically silenced.
