What is the Function of Cerebral Cortical Activation?

  • C. H. Vanderwolf


The preceding chapters have shown that many aspects of cerebral cortical electrical activity occur in close temporal correlation with the details of motor activity. However, the demonstration of a correlation between a brain electrical event and the occurrence of a movement is not sufficient to establish the significance of the cerebral electrical event in question. The fact that two events are correlated does not necessarily mean that one is the cause of the other. Both may be caused by some unknown third factor. This logical difficulty can be surmounted if the hypothesized causal factor can be eliminated in some way. For example, does surgical or pharmacological blockade of cerebral electrocortical activation have an effect on behavior? If it does, such activation may play a role in causing the behavior.

It is interesting that several psychotomimetic drugs (cyclazocine, normetazocine, phenylcyclidine, and phenylcyclohexylamine) suppress both atropine-resistant hippocampal rhythmical slow activity and atropine-resistant neocortical low voltage fast activity in a selective manner [Vanderwolf, C.H. (1987). Suppression of serotonin-dependent cerebral activation: a possible mechanism of action of some psychotomimetic drugs. Brain Research, 414: 109–118] and also produce (at least in the case of cyclazocine) a marked increase in the impairment produced by scopolamine in swim-to-platform performance in rats. [Buckton, G., Zibrowski, E.M. and Vanderwolf, C.H. (2001). Effects of cyclazocine and scopolamine on swim-to-platform performance in rats. Brain Research, 922: 229–233]. Thus, in terms of large-scale cerebral electrophysiology and behaviour, these psychotomimetic drugs have effects similar to the effects ofp-chlorophenylalanine. The basis of this similarity deserves further investigation.Google Scholar

This paper developed from an undergraduate teaching laboratory exercise. Colin Ellard (a graduate student working with my colleague Mel Goodale in the years 1982–86), and Dwight Stewart (a graduate student working with me) were teaching assistants in an undergraduate laboratory course on the brain and behavior which I taught for many years. One of the laboratory exercises that students were asked to complete consisted of observation of the effects of large neocortical lesions in the Mongolian gerbil. Gerbils were chosen for this primarily because they remain lively and active in the bright, noisy environment of a student laboratory, a situation that elicits prolonged periods of crouching immobility in rats. Colin and Dwight became quite intrigued by this project, and with the assistance of Steve Donaghy, who needed a project for an undergraduate thesis, they produced an interesting paper showing, among other things, that several Type 2 behaviors were less affected by cortical lesions than Type 1 behaviors. Grooming behavior was affected by cortical lesions in much the same way that it is in rats.Google Scholar
