Springer Evoked Brain Potentials in Psychiatry 1st Editon 2013 Softbound by Charles Shagass
Two purposes have guided the writing of this book. Originally, I wanted only to bring together the results which we have obtained during more than ten years of work on evoked potentials in psychiatric disorders. However, it soon became clear that I really wanted to do a little more than that. First of all, a systematic review of the literature seemed indicated. Even though research findings are usually presented in the context of such a review, our laboratory has not studied every aspect of evoked potentials. Consequently, it seemed more appropriate to place our own results within the framework of a general presentation of the evoked-potential field, rather than to have our specific studies govern topic selection. Second, I found that I wanted to expound on the principles and details of techniques to a broader extent than warranted for presenting only our own results. The motivation for attempting such a 'methodological primer' came not only from my long-term preoccupation with technical issues, but from contacts with many investigators who consulted me during the early stages of their ventures into evoked-potential research. Thus, to the initial goal of a re search monograph was added that of a systematic account of both the substantive findings and the methodology of the field. 1 Introduction.- Some Historical Background.- Development of the Writer’s Evoked-Response Research.- 2 Techniques.- Averaging: Concepts and Limitations.- General Recording Conditions.- Averaging Instruments.- Additional Instruments for Recording.- Stimulus Problems.- Quantification and Data Reduction.- 3 Characteristics of Event-Related Potentials.- Somatosensory Responses.- Auditory Responses.- Visual Responses.- Motor Potentials.- Long Latency Potentials.- Contingent Negative Variation and Other Steady Potential Shifts.- 4 Age, Sex, and Other Factors.- Somatosensory Responses and Age.- Somatosensory Responses and Sex.- Auditory Responses, Age, and Sex.- Visual Responses and Age.- Visual Responses and Sex.- Contingent Negative Variation.- Handedness.- Time of Day.- Respiratory and Cardiac Cycles.- Comment.- 5 Evoked Responses and Impaired Consciousness.- Sleep Stages.- Somatosensory Evoked Responses and Sleep.- Auditory Responses and Sleep.- Visual Responses and Sleep.- Comment.- Delirium.- Coma.- Comment.- 6 Attention and Related Phenomena.- Habituation.- Directed Attention.- Hypnosis and Suggestion.- Distraction.- Long-Latency Potentials.- Contingent Negative Variation (CNV).- Comment.- 7 EEG-Evoked Response Relationships.- Between-Subjects Correlations.- Experimental Manipulation of the EEG.- Within-Subject Relationships.- EEG-Evoked Response Relationship as a Psychophysiological Variable.- 8 Intelligence and Personality.- Intelligence.- Questionnaire Tests of Personality.- Perceptual or Performance Tests of Personality.- Contingent Negative Variation.- Sedation Threshold.- Comment.- 9 Functional Psychiatric Disorders.- Evoked Responses to Unpaired Stimuli.- Variability of Evoked Responses in Time and Space.- Somatosensory Evoked-Response Recovery Functions.- Additional Studies of Somatosensory Recovery Functions.- Modified Somatosensory Recovery Function Procedure.- Auditory Evoked-Response Recovery Functions.- Visual Evoked-Response Recovery Functions.- Contingent Negative Variation.- Comment.- 10 Effects of Pharmacologic Agents.- Preanesthetics and Anesthetics.- Psychoactive Agents.- Thyroid Function.- Psychotogenic Agents.- Comment.- 11 Conclusion.- References.
