The scientist’s investigation covers issues in Anesthesia, Neuroscience, Internal medicine, Heart rate and Cardiology. His Anesthesia research is multidisciplinary, relying on both Autonomic nervous system, Sleep in non-human animals, Tongue and Sudden infant death syndrome. His Neuroscience research focuses on subjects like Anatomy, which are linked to Forebrain, Diffusion MRI, Cerebellar cortex, Putamen and Temporal cortex.
He combines subjects such as Endocrinology and Brain mapping with his study of Internal medicine. The study incorporates disciplines such as Rapid eye movement sleep, Electrocardiography and Respiratory system in addition to Heart rate. Ronald M. Harper interconnects Epilepsy, Quiet sleep, Surgery and Respiration in the investigation of issues within Cardiology.
His main research concerns Internal medicine, Neuroscience, Anesthesia, Cardiology and Sleep in non-human animals. The various areas that Ronald M. Harper examines in his Internal medicine study include Endocrinology, Magnetic resonance imaging and Epilepsy. In general Neuroscience, his work in Hippocampus, Functional magnetic resonance imaging, Hippocampal formation and Electrophysiology is often linked to Chemistry linking many areas of study.
His studies deal with areas such as Sudden infant death syndrome, Blood pressure, Heart rate and Respiratory system as well as Anesthesia. As a part of the same scientific study, he usually deals with the Sleep in non-human animals, concentrating on Audiology and frequently concerns with Developmental psychology. His biological study spans a wide range of topics, including Sleep apnea and Sleep disorder.
Ronald M. Harper focuses on Internal medicine, Cardiology, Obstructive sleep apnea, Epilepsy and Neuroscience. In his research on the topic of Internal medicine, Glutamate receptor is strongly related with Endocrinology. His Cardiology research incorporates themes from Heart rate variability, Insula, Baroreflex and Polysomnography.
His Obstructive sleep apnea study integrates concerns from other disciplines, such as Thalamus, Sleep disorder, Pathology, Apnea–hypopnea index and Sleep apnea. His research integrates issues of Amygdala, Posterior cingulate and Electroencephalography in his study of Epilepsy. His studies in Ictal integrate themes in fields like Central apnea, Serotonin, Anesthesia and Brainstem.
Internal medicine, Neuroscience, Obstructive sleep apnea, Epilepsy and Cardiology are his primary areas of study. His Internal medicine study combines topics in areas such as Endocrinology and Brain size. His Neuroscience research is multidisciplinary, incorporating elements of Autonomic nervous system, Risk stratification and Breathing.
His Obstructive sleep apnea study incorporates themes from Sleep apnea, Basal ganglia, Sleep disorder and Pathology. His Cardiology research includes themes of Cerebellum, Uncus, Frontal lobe and Hippocampal formation. His Thalamus research includes elements of White matter, Magnetic resonance imaging and Anesthesia.
