Hemimotor Neglect
Hemimotor neglect or simply motor neglect is a neuropsychological condition that occurs after damage to one hemisphere of the brain, characterized by a failure of spontaneous use of upper and lower limbs on one side of body. It occurs in the absence of paralysis, pyramidal syndromes, extrapyramidal symptoms, strength and primary sensory deficit.Sampanis, D.S. e Riddoch, J. (2013) Motor neglect and future directions for research. Frontiers Human Neuroscience, 7, 110 Presentation Motor neglect can occur in isolation from, or in association with hemispatial neglect, making the pathological state more complicated in at least 30% of patients with brain damage.Saevarsson, S (2013). Motor Response Deficits of Unilateral Neglect: Assessment, Therapy, and Neuroanatomy. Applied Neuropsychology Adult, 0, 1–14 Motor neglect has been described in different terms: disorders and intentional neglect; motor hemi neglect; thalamic, nonsensory neglect; and callosal neglect.

Brain
A brain is an organ that serves as the center of the nervous system in all vertebrate and most invertebrate animals. It is located in the head, usually close to the sensory organs for senses such as vision. It is the most complex organ in a vertebrate's body. In a human, the cerebral cortex contains approximately 14–16 billion neurons, and the estimated number of neurons in the cerebellum is 55–70 billion. Each neuron is connected by synapses to several thousand other neurons. These neurons typically communicate with one another by means of long fibers called axons, which carry trains of signal pulses called action potentials to distant parts of the brain or body targeting specific recipient cells. Physiologically, brains exert centralized control over a body's other organs. They act on the rest of the body both by generating patterns of muscle activity and by driving the secretion of chemicals called hormones. This centralized control allows rapid and coordinated respon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
