The central nervous system (CNS) is the part of the nervous system consisting primarily of the brain, spinal cord and retina.The CNS is so named because the brain integrates the received information and coordinates and influences the activity of all parts of the bodies of bilaterally symmetric and triploblastic animals—that is, all multicellular animals except sponges and diploblasts.
Consisting of the central nervous system (CNS), which includes the brain and spinal cord, and the peripheral nervous system (PNS), which extends throughout the rest of the body, this system is responsible for transmitting signals between different parts of the body and facilitating the coordination of various physiological functions. Neurons ...
Psychophysiology measures exist in multiple domains; reports, electrophysiological studies, studies in neurochemistry, neuroimaging and behavioral methods. [5] Evaluative reports involve participant introspection and self-ratings of internal psychological states or physiological sensations, such as self-report of arousal levels on the self-assessment manikin, [6] or measures of interoceptive ...
Neurophysiology is a branch of physiology and neuroscience concerned with the functions of the nervous system and their mechanisms. The term neurophysiology originates from the Greek word νεῦρον ("nerve") and physiology (which is, in turn, derived from the Greek φύσις, meaning "nature", and -λογία, meaning "knowledge"). [1]
The enteric nervous system functions to control the gastrointestinal system. Nerves that exit from the brain are called cranial nerves while those exiting from the spinal cord are called spinal nerves. The nervous system consists of nervous tissue which, at a cellular level, is defined by the presence of a special type of cell, called the ...
A decussation denotes a crossing of bundles of axonal fibres inside the central nervous system. Due to decussations the efferent connections of the cerebrum to the basal ganglia, the cerebellum and the spine are crossed; and the afferent connections from the spine, the cerebellum and the pons to the thalamus are crossed.
Computational neuroscience includes both the study of the information processing functions of the nervous system, and the use of digital computers to study the nervous system. It is an interdisciplinary science that links the diverse fields of neuroscience, cognitive science and psychology, electrical engineering, computer science, physics and ...
The largest of these contributions was that the biological central nervous system can be linked to a psychological reward system, composed of approach and inhibition systems. [13] Gray's model of personality was based on three hypothesized brain systems: Behavioral activation system (BAS)
