. tM.Asfor tM, the intrinsic signal is faster than the extrinsic signal,however, the timing of the combined signal is between the intrinsic and the extrinsic signal, which results in Si<1.SK<. and s) are smaller for the extrin-sic stimulus (a) than for the intrinsic stimulus (b). Contraryto Table 3, the response to the combined signal is between the intrinsic and the extrinsic response,. Si> 1, the activation by the intrinsic signal is stronger than the integrated response andindicates that when both signals are transmitted the extrin-sic signal inhibits the intrinsic signal,...
