    Abstract:
    In acute experiments on rats, focal potentials characteristics were compared with responses of 63 neurones of the thalamic dorsomedial nucleus (DMN) to stimulation of the anterior amygdalar area (AAA), anterior periamygdalar cortex (APC) and basolateral amygdala (BLA). A resemblance was established of parameters of DMN evoked responses to APC and BLA stimulation. At DMN level, interaction of inputs from BLA and APC and to a lesser degree from AAA and BLA was discovered, expressed in suppression of the evoked activity to testing stimulation in the interval of 50-500 ms after conditioning stimulation. It is shown that the inputs from the structures of the amygdalar complex to DMN are of different effectiveness. 30% of tested neurones were characterized by convergence of the inputs from APC and BLA. APC coagulation was followed by a reduction of focal potentials evoked by BLA stimulation and by their complete disappearance in the ventral part of DMN. It is supposed, that APC in rats is the main relay structure between BLA and DMN.
