Özet
In this study, mechanisms of formation of thalamocortical spindle oscillations, which are critical for various functions of the brain, have been examined on a model basis. For this, both spike activity and spectral characteristics were investigated by isolating the cortex and thalamus and then connecting them with thalamo-cortical projections. In order to determine the spindle activity in the LFP signal of each cell group, it has been tried to determine slow-wave and spindle frequency components which can coexist with each other on the basis of superposition. For this purpose, power spectral densities of LFP signals were analyzed. According to the results of this study, spindle activity can be seen in thalamus without cortex. It can be said that thalamo-cortical projections provided by the thalamic TC cells enable the spindle activity to be transferred into the cortex and thus display itself in LFP / EEG. At the same time, it has been observed that thalamo-cortical projections increase spike activity, equalize the dominant frequency in the whole system, and also cortico-thalamic projections strengthen spindle activity. © 2017 IEEE.
