Ortho-antidromic latency fitting and identification of antidromically activated CNS long-axoned neurones.
The intrinsic errors of the collision test were evaluated in extracellular recordings of cat's pyramidal tract (PT)-units. A modified collision technique by means of paired and suitably timed PT-stimuli allowed the demonstration of the ortho-antidromic latency fitting. This method could represent an important counterproof to the true antidromic activation of CNS long-aconed neurons.
