Mechanism of Neural Control

Neurological disorders are among the leading cause motor movement disorders in patients. The neuro control system helps in enhancement of the neuro transmission in the body. The devices are planted on the patients skull that stimulates the impulse. Nerve cells called neurons generate electric signals that pass from one end of the cell to another and release chemical messengers called neurotransmitters to communicate with other cells.

The respiratory rhythm generator is spectacular in its ability to support a wide range of activities and adapt to changing environmental conditions, yet its operating mechanisms remain elusive. We show how selective control of inspiration and expiration times can be achieved in a new representation of the neural system.

Axons of some neurons are covered by myelin, a layer of plasma membranes with supporting cells that are called glial cells in CNS and Schwann cells in the peripheral nervous system. The spaces between adjacent sections of myelin where the axon is exposed to extracellular fluid are called nodes of Ranvier. Myelin speeds up the conduction of electric signals.

The human hand is an ideal model system to address fundamental questions in motor and cognitive neuroscience: How does the nervous system control multiple degrees of freedom? What makes a learned movement interfere or facilitate executing the same movement in a different context? How are multiple sources of sensory feedback integrated to generate coordinated movements? How do memory and online feedback interact when planning and executing movement? What are the neural representations of learned movements?

The cerebral cortex is never quiet. From the deepest sleep to solving complex cognitive tasks, cortex displays robust ‘spontaneous activity’ which is not associated with specific sensory or motor content. Far from being intrinsic noise, we now recognize that spontaneous cortical activity reflects dynamic self-organization into various states which biases sensory and motor processing according to internal drives. In the following sections, we provide perspectives about cortical state diversity, mechanisms of modulation, effects on sensory processing and involvement in higher cognitive function. In this review, ‘modulation of cortical state’ refers to both fast (presumably ionotropic-mediated) and slow (metabotropic-mediated) mechanisms, in contrast to ‘neuromodulatory pathways’ which refers to long-range, primarily metabotropic connections.
