Inhibitory summation as a form of generalization.

WebbInhibitory summation as a form of generalization. Inhibitory learning after feature negative training (A+/AB–) is typically measured by combining the Feature B with a separately trained excitor (e.g., C) in a summation test. Reduced responding to C is taken as evidence that B has properties directly opposite to those of C. Webbsummation. This is obvious: one need merely introduce a suitable sequence of delaying chains, of increasing numbers of synapses, between the exciting cell and the neuron whereon temporal summation is desired to hold. The assumption of spatial summation will then give the required results (see e.g. Fig. lh). This taunton high school athletics schedule https://stealthmanagement.net
