Role of the Posterior Parietal Cortex in the Processing of Sensory Information

2018-01-08 07:47:09 | BioPortfolio

Summary

Although the primary motor cortex is considered has the common final pathway of motor commands, it is influenced by several structures as, for example, the premotor cortex and the posterior parietal cortex which are involved in motor planning and programming and which integrates movement-induced sensory impute (parieto-frontal circuits). Several studies have shown that there are some direct functional connections between the premotor cortex and the posterior parietal cortex and from these two regions to the primary motor cortex. The posterior parietal cortex can then be considered as a sensorimotor interface whose function in planification and motor control of upper limb is well demonstrated. The hypothesis is that the posterior parietal cortex could participate to the modulation of motor cortex excitability by proprioceptive sensory inputs namely long latency afferent inhibition and afferent induced facilitation.

Medical and Biotech [MESH] Definitions

The electrical response evoked in a muscle or motor nerve by electrical or magnetic stimulation. Common methods of stimulation are by transcranial electrical and TRANSCRANIAL MAGNETIC STIMULATION. It is often used for monitoring during neurosurgery.

Measurable changes in activities in the CEREBRAL CORTEX upon a stimulation. A change in cortical excitability as measured by various techniques (e.g., TRANSCRANIAL MAGNETIC STIMULATION) is associated with brain disorders.

Prolonged failure of muscle relaxation after contraction. This may occur after voluntary contractions, muscle percussion, or electrical stimulation of the muscle. Myotonia is a characteristic feature of MYOTONIC DISORDERS.

A technique of brain electric stimulation therapy which uses constant, low current delivered via ELECTRODES placed on various locations on the scalp.

A technique that involves the use of electrical coils on the head to generate a brief magnetic field which reaches the CEREBRAL CORTEX. It is coupled with ELECTROMYOGRAPHY response detection to assess cortical excitability by the threshold required to induce MOTOR EVOKED POTENTIALS. This method is also used for BRAIN MAPPING, to study NEUROPHYSIOLOGY, and as a substitute for ELECTROCONVULSIVE THERAPY for treating DEPRESSION. Induction of SEIZURES limits its clinical usage.
