The connection between the dynamics of sliding means of both parameters was analysed. It was found that a reduction of RT correlated with stabilization of electrical cortical responses. The change in the signals alternation produced an interrelated lengthening of RT and dispersion of EP amplitudes, particularly pronounced for its early phases. Distinct interconnection between RT shortening and reduction of dispersions of EP components reflects the organization of a representative system, which provides for the enhancement of the level of pre-tuning (readiness) for perception of the highly probable sequence of the signals. Hypothesis of reflection of reverberation processes in the EP waves permits a satisfactory explanation of EP variability in signals recognition.</p>","PeriodicalId":24031,"journal":{"name":"Zhurnal vyssheĭ nervnoĭ deiatelnosti imeni I P Pavlova","volume":" ","pages":"209-17"},"PeriodicalIF":0.3,"publicationDate":"1982-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35218420","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Equally high reactivity to the all three substances was observed (86-88% of reactive units). Ach evoked slowly developing moderate increase of spontaneous activity in 63% of the units; in 24% it enhanced, accelerated, or evoked rhythmic bursts (1-3,5 per s). NE evoked higher and rapidly developing activation in 73% of the units; 5HT increased or decreased the level of activity in equal proportions of the cells (45% each). Both NE and 5HT neither provoked nor intensified rhythmic burst activity. Activatory and inhibitory effects of NE, 5HT and Ach were not blocked in the medium with high Mg2+ concentration. Burst activity disappeared in this condition in some units, but was preserved in the others. It is concluded that in some of the septal units transmitter substances modulate the activity of endogenous pacemaker mechanism.</p>","PeriodicalId":24031,"journal":{"name":"Zhurnal vyssheĭ nervnoĭ deiatelnosti imeni I P Pavlova","volume":" ","pages":"319-26"},"PeriodicalIF":0.3,"publicationDate":"1982-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"35357094","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
