The influence of orotic acid on cortical excitability processes and cerebral circulation was studied in acute experiments in cats. The effect on CNS excitability was assessed by examination of the cortical visual-evoked potentials and the recovery cycles. The flash-evoked responses were recorded from visual cortex (VC), associative cortex (AsC) and auditory(More)
The aim of this study was to evaluate how far the variations in the P300 amplitude of the event-related potentials (ERP) are related to the changes in the frequency of P300 occurrence from the polarity histogram. ERP from Cz (10/20 system) in a task of counting one of two different stimuli ("soft" and "loud" tones) presented in a Bernoulli sequence were(More)
