ABSTRACT
H;j(s) = O(i,s)jq>(j,s). This is the transform of the impulse response, hjj(t), which can be convolved with the input to yield the output:
w(i, t) = h;j(t) * cp(j, t). (Throughout this paper "*" is the convolution operation.) In particular, if Cpj is a Dirac delta (impulse) function, then:
w(i,t) = hiAt). That is, injecting an impulse into input j causes the signal hjj(t) at output i. This is only approximate, since a nerve impulse (an action potential) is a' poor approximation to a delta functionj nevertheless it suggests the general form of the output (h;j blurred by convolution with the action potential).
