His primary areas of investigation include Neuroscience, Cognitive psychology, Temporal lobe, Functional imaging and Artificial intelligence. As a member of one scientific family, Alexander P. Leff mostly works in the field of Neuroscience, focusing on Reading and, on occasion, Audiology. Alexander P. Leff has researched Cognitive psychology in several fields, including Semantic memory and Superior temporal sulcus.
His work in Temporal lobe tackles topics such as Temporal cortex which are related to areas like Perirhinal cortex, Stimulus modality, Temporal lobe/cortex and Sensory system. The concepts of his Artificial intelligence study are interwoven with issues in Machine learning, Causal model and Pattern recognition. His Spatial normalization research includes themes of Normalization and Brain lesions.
His primary areas of study are Stroke, Audiology, Neuroscience, Aphasia and Cognitive psychology. His Stroke study combines topics in areas such as Psychological intervention, Lesion, Physical medicine and rehabilitation, Cognition and Lateralization of brain function. His Audiology research includes elements of Speech production, Magnetoencephalography and Dyslexia, Reading.
His studies in Reading integrate themes in fields like Hemianopsia and Eye movement. His research in the fields of Comprehensive Aphasia Test overlaps with other disciplines such as Language therapy. Alexander P. Leff combines subjects such as Auditory cortex, Speech perception, Functional imaging, Functional magnetic resonance imaging and Temporal lobe with his study of Cognitive psychology.
Stroke, Aphasia, Audiology, Physical medicine and rehabilitation and Lesion are his primary areas of study. His research in Stroke intersects with topics in Lateralization of brain function, Cognition and Cardiology. Alexander P. Leff interconnects Comprehension, Utterance, Artificial intelligence and Natural language processing in the investigation of issues within Aphasia.
His Artificial intelligence research incorporates elements of Aphasia Treatment and Language disorder. The various areas that Alexander P. Leff examines in his Audiology study include Pure alexia, Dyslexia, Neuropsychology and Speech production. Dyslexia is a subfield of Reading that Alexander P. Leff explores.
His primary scientific interests are in Stroke, Physical medicine and rehabilitation, Rehabilitation, Psychological intervention and Cognition. His Stroke study incorporates themes from Statistics and Outcome. His Physical medicine and rehabilitation research is multidisciplinary, incorporating elements of Clinical effectiveness, Neglect and Visual search.
His Rehabilitation research incorporates themes from Meta-analysis and Aphasia. His Psychological intervention study integrates concerns from other disciplines, such as Stroke recovery, Quality of life, Cognitive rehabilitation therapy, Individual participant data and Neurology. His studies deal with areas such as Visual perception and Lesion as well as Cognition.
