A neural substrate is a term used in neuroscience to indicate the part of the central nervous system (i.e., brain and spinal cord) that underlies a specific behavior, cognitive process, or psychological state.[1][2] Neural is an adjective relating to "a nerve or the nervous system",[3] while a substrate is an "underlying substance or layer".[4]
Some examples are the neural substrates of language acquisition,[5] memory,[6] prediction and reward,[7] pleasure, facial recognition,[8] envisioning the future,[9] intentional empathy,[10] religious experience,[11] spontaneous musical performance,[12] and anxiety.[13]
neural substrates
functional units of the central nervous system, often composed of a series of structural units which may be widely separated anatomically but which interact to support or drive complex nervous system functions, such as hunger and sleepiness. They are the counterparts of simple centers, e.g. the respiratory center, which control simple physiological mechanisms.
Further, clear definition of how language and its underlying neural substrates are affected as we become older will assist clinicians and others in communicating clearly with older persons.
