Trigeminal neuralgia ( TN or TGN ), also called Fothergill disease, tic douloureux, trifacial neuralgia, or suicide disease, is a long-term pain disorder that affects the trigeminal nerve, [ 7][ 1] the nerve responsible for sensation in the face and motor functions such as biting and chewing. It is a form of neuropathic pain. [ 8]
Trigeminal nerve. In neuroanatomy, the trigeminal nerve ( lit. triplet nerve), also known as the fifth cranial nerve, cranial nerve V, or simply CN V, is a cranial nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the most complex of the cranial nerves.
Psychiatry, Neurology. Right hemisphere brain damage ( RHD) is the result of injury to the right cerebral hemisphere. [1] The right hemisphere of the brain coordinates tasks for functional communication, which include problem solving, memory, and reasoning. [1] Deficits caused by right hemisphere brain damage vary depending on the location of ...
Magnetic resonance imaging. Hemianopsia, or hemianopia, is a visual field loss on the left or right side of the vertical midline. It can affect one eye but usually affects both eyes. Homonymous hemianopsia(or homonymous hemianopia) is hemianopic visual field loss on the same side of both eyes. Homonymous hemianopsia occurs because the right ...
Cerebellopontine angle syndrome. The cerebellopontine angle syndrome is a distinct neurological syndrome of deficits that can arise due to the closeness of the cerebellopontine angle to specific cranial nerves. [ 1] Indications include unilateral hearing loss (85%), speech impediments, disequilibrium, tremors or other loss of motor control.
There are many holes in the skull called "foramina" by which the nerves can exit the skull. All cranial nerves are paired, which means they occur on both the right and left sides of the body. The muscle, skin, or additional function supplied by a nerve, on the same side of the body as the side it originates from, is an ipsilateral function.
Split-brain or callosal syndrome is a type of disconnection syndrome when the corpus callosum connecting the two hemispheres of the brain is severed to some degree. It is an association of symptoms produced by disruption of, or interference with, the connection between the hemispheres of the brain. The surgical operation to produce this ...
Cerebral hemisphere. Human brain seen from front. The vertebrate cerebrum ( brain) is formed by two cerebral hemispheres that are separated by a groove, the longitudinal fissure. The brain can thus be described as being divided into left and right cerebral hemispheres. Each of these hemispheres has an outer layer of grey matter, the cerebral ...
