Moruzzi and Magoun first investigated the neural components regulating the brain’s sleep-wake mechanisms in 1949. Physiologists had proposed that some structure deep within the brain controlled mental alertness. It used to be thought that wakefulness depended directly on the transmission of afferent sensory stimuli to the cerebral cortex. Magoun first demonstrated that direct electrical stimulation [...]

As the above quotation shows, Müller’s law seems to differ from the modern statement of the law in one key way. Müller attributed the quality of an experience to some specific quality of the energy in the nerves. For example, the visual experience from light shining into the eye, or from a poke in the [...]
Radical retropubic prostatectomy was developed in 1945 by Terence Millin at the All Saints Hospital in London. The procedure was brought to the United States by one of Millin’s students, Samuel Kenneth Bacon, M.D., adjunct professor of surgery, University of Southern California, and was refined 1982 by [http://urology.jhu.edu/patrickwalsh/index.php Patrick C. Walsh] at the James Buchanan [...]
Treatments will vary. In most cases, the best treatment is to remove the cause of the compression by modifying patient behavior, in combination with medical treatment to relieve inflammation and pain. The following treatments are examples. Whatever the cause, recovery typically requires several weeks to months, depending on the severity of nerve damage, and is [...]
Nav1.7 is a voltage-gated sodium channel and plays a critical role in the generation and conduction of action potentials and is thus important for electrical signaling by most excitable cells. Nav1.7 is released at the endings of pain-sensing nerves, the nociceptors, close to region where the impulse is initiated. Stimulation of the nociceptor nerve endings [...]
Raageshwari (full name Raageshwari Loomba) was born in Mumbai on the 25 July 1977 in a middle-class family, to Trilok Singh Loomba, a National Award winning musician and government servant, and his wife Veera. She has an elder brother, Rishabh who is a filmmaker. The Sanskrit word ”Raageshwari” means “the queen of ”ragas” and wife [...]
Physical medicine and rehabilitation involves the management of disorders that alter the function and performance of the patient. Emphasis is placed on the optimization of function through the combined use of medications, physical modalities, physical training with therapeutic exercise, movement & activities modification, adaptive equipments and assistive device, orthotics (braces), prosthesis, and experiential training approaches. [...]
evoked potential (or “evoked response”) is an electrical potential recorded from the nervous system of a human or other animal following presentation of a stimulus, as distinct from spontaneous potentials as detected by electroencephalography (EEG) or electromyography (EMG). Evoked potential amplitudes tend to be low, ranging from less than a microvolt to several microvolts, compared [...]
The CN is the first relay station in the auditory system and is located at the dorso-lateral side of the brainstem, spanning the junction of the pons and medulla. Information is brought via the cochlear nerve, a part of Cranial nerve VIII (the vestibulocochlear nerve), to the CN. The cochlear nucleus can be divided into [...]
Somatosensory Evoked Potentials (SEPs or SSEPs) are a useful, noninvasive means of assessing somatosensory system functioning. By combining SEP recordings at different levels of the somatosensory pathways, it is possible to assess the transmission of the afferent volley from the periphery up to the cortex. SEP components include a series of positive and negative deflections [...]
