[Impulse synchronization in the mechanisms of adaptive plasticity of neuronal populations of the posterior hypothalamus].
An increase in the firing rate induced minimization of the reward (a weak electrical skin stimulation) and altered the neuronal activity patterns in the posterior hypothalamus. The estimation of the expected random coincidence functions between the two neuronal activity trains belonging to adjacent cells showed the synchronization both in high- and low-frequency ranges. In the process of adaptive alterations of the neuronal activity, fluctuations of the expected randon coincidence coefficients occurred.
