[Mixed and antidromal cortical responses evoked by electrical stimulation of the splenial portion of the corpus callosum].
In anesthetized cats, antidromic and orthodromic components were shown to be represented unequally in the mixed responses to the splenium stimulation recorded from various areas of the cortex.  Orthodromic component makes about 50 per cent of the mixed response amplitude in the area 17, while in the area 18 and in middle part of the suprasylvian gyrus it makes about 70 per cent.  In the regions beyond focus the mixed responses disappeared because of falling out of the orthodromic impulses.  During antidromic recording of the responses, only deep layers got activated at weak stimuli, while both deep and superficial ones were involved at stronger stimulation.
