Abstract: | Cortical incremental responses to repetitive thalamic stimulation were studied in normal and protein malnourished rats. The rate of cortical incrementation ipsilateral to the thalamic site of stimulation varied as a function of stimulus repetition rate but was unaffected by dietary treatment. The waveform of the ipsilateral response likewise was unaffected by protein malnutrition and a characteristic positive-negative-positive response was observed. In the cortex contralateral to thalamic stimulation, seven of eight malnourished animals exhibited a surface positive peak, in some cases quite prominent, at a latency at which seven of eight normals exhibited a prominent surface negativity. These results are discussed in relation to reported effects of malnutrition on sensory evoked potentials. |
