WebIn order to account for the observed auditory-evoked activity changes in HVC, we mirrored the feedforward phasic inhibition model (Figs. 1 and 2E) to include an upstream excitatory “auditory” population and a local interneuron population. These were connected through the same circuit motif of excitation and feedforward inhibition (Fig. 4A). WebMay 6, 2024 · Thalamic recruitment of feedforward inhibition is known to enhance the fidelity of the receptive field by limiting the temporal window during which cortical neurons integrate excitatory inputs. Feedforward inhibition driven by the mediodorsal nucleus of the thalamus (MD) has been previously observed, but its physiological function and …

WebInterneuron activation generally precedes principal cell activation when both are driven by a given afferent path. At least some interneurons take a part in both feed-back and feed-forward inhibition. It is suggested that most of the major inputs to the hippocampal formation dually innervate both interneurons and principal cells and that the ...
