Screening Methods in Pharmacology focuses on the methods for screening substances for pharmacological activities and discussions of organization of screening programs. The manuscript first offers information on the biochemistry of the nervous system and organization of screening, as well as mechanisms of drug effects within the autonomic system; mechanisms within the parasympathetic and symphatetic systems; and neuropharmacological tests in blind screening. The book also takes a look at general and quantal responses. The publication reviews depressants of the central nervous system and ataractic (tranquillizing, neuroleptic) agents. Topics include natatory exhaustion, motor deficit, righting reflex, pentylenetetrazol (metrazol) antagonism, head-withdrawal reflex, and avoidance of electrical shock. The book also ponders on analgesics and oxytoxic, antiserotonin, and anti-inflammatory agents. Discussions focus on narcotic and nonnarcotic analgesics, erythema, inhibition of ascites, and pleural fluid. The manuscript is a valuable reference for readers interested in the screening methods in pharmacology.

Dr. Robert Turner is currently the owner and CEO of Network Neurology in Charleston SC. He is also Associate Clinical Professor of Neurosciences at the Medical University of South Carolina in Charleston, as well as an Associate Researcher with the MIND Research Institute in Irvine CA. Dr Turner maintains a full-time clinical, teaching, and neurophysiology practice with patients throughout the southeastern region of the United States. While continuing full time work at MUSC since 1997, he obtained a Master's degree in clinical research (epidemiology & biostatistics) in 2003 in the MUSC College of Graduate Studies, and has since then been actively involved in ongoing clinical research with collaborative studies in non-invasive neurostimulation and neuromodulation techniques as well as advanced techniques of EEG source analysis. Current research involves collaborating with colleagues in Charleston, Cape Town, South Africa, Mexico City, Bejing, and with several academic practices throughout the United States. Dr Turner began as a music and foreign language major in college, changing over to pre-medicine in his 3rd year. During medical school, he also pursued Master's training in Piano Performance at the University of Nebraska at Omaha Graduate School. After Medical School, his postgraduate training consisted of internship/residency in Pediatrics followed by two fellowships, one in Adult/Child Neurology, and the second in Clinical Neurophysiology/EMG/Neuromuscular Disorders, and his current clinical/research emphases are pediatric epilepsy/epileptogenesis, the non-linear effects of auditory and music stimulation on the brain, as well as neuromodulation techniques. He continues to pursue his love of music, and is an accomplished classical pianist. He has received numerous awards and honors in Charleston over the past 16 years, including multiple Faculty Excellence Awards for teaching, AREA Awards for excellence in ambulatory care, Golde Apple Nominations and Awards, and double honors in humanism with the AAMC Humanism in Medicine Award and the Leonard Tow Humanism in Medicine AwardDr. Turner is multiply Board-Certificated by the National Board of Medical Examiners, became a certified member of the American Society of Neurorehabilitation in 1992, and has eight medical specialty boards certifications:1. American Board of Psychiatry and Neurology With Special Qualification in Child Neurology,2. American Board of Pediatrics,3. American Board of Electrodiagnostic Medicine, 4. American Board of Clinical Neurophysiology,5. American Board of Psychiatry and Neurology With Added Qualification in Clinical Neurophysiology,6. American Board of Psychiatry and Neurology With Added Qualification in Neurodevelopmental Disabilities ,7. Quantitative Electroencephalograpy (QEEG) Certification Board, and8.
