inhibitory synaptic activity in the parent motoneuron will also be ineffective in reducing excitatory potentials in the A1 unit, since, regarded from the A1 unit, such inhibitory activity will have the properties of “dendritic remote inhibition” ( Diamond, 1968). The net result
of all this is that the A1 unit is relatively noise free.
B. The Implication of a Noise-Free System
Consider Fig. 31, which shows diagrammatically how the latency of
spike firing will be influenced by the presence of noise. The noise we
are now considering represents activity in the motoneurons during the
