Neurophysiological Observations

This classical view of the connectivity of the basal ganglia has been modified to some extent over the last decade by new information relating to the neuroanatomy and physiology of the striatum, and from molecular biology. Although the classical model fits in many ways with neurophysiological studies and clinical observations (i.e., lesioning STN and GPj improves motor... 

Figure 6.4 Types of intestinal motility patterns. Segmentation, tonic contraction, and peristalsis are the three major types of motility patterns observed in the gut. Each serves a specific function for digestion and processing of luminal contents. From E.B. Chang, M.D.Sitrin and D.D.Black (1996) Gastrointestinal motility and neurophysiology. Gastrointestinal, Hepatobiliary, and Nutritional Physiology, Lippincott-Raven, Philadelphia, pp. 27-51...

The findings on the long-term effect of exposure—in particular, RADS and neurophysiologic and neuropsychologic effects—are equivocal. Clinical changes have been observed on x-rays, but not all studies have addressed other potential causes, such as cigarette smoking or unrelated occupational exposures. 

A putative role for nAChRs in schizophrenia was suggested by the high rate of smoking in schizophrenic patients and the observation that nicotine normalizes neurophysiological deficits associated with the disease. As described elsewhere in this review, subsequent studies provided strong evidence for a role of nAChRs in the... 

Although there is some modern evidence from neurophysiological research for the anatomical and functional distinctness of these three brains, it is their observable functional qualities that matter for our discussion. I shall continue to use the word brain, but don t be concerned with the anatomy of the physical brain. Gurdjieff used centers at times rather than brain, and also spoke of other centers and finer divisions of these centers, but that level of detail will not concern us here. 

Long-term exposure to carbon disulfide via inhalation has been reported to result in neurological effects such as polyneuropathy, neurophysiologic changes, and general depression of nerve conduction velocities in humans. Cardiovascular effects that have been observed following chronic inhalation of carbon disulfide vapors by workers include generalized symptoms of heart disease, vascular...
