Question

Hebb's postulate from 1949 states "When an axon of cell A is near enough to excite cell B and repeatedly or persistently takes part in firing it, some growth process or metabolic change takes place in one or both cells such that A's efficiency, as one of the cells firing B, is increased." Give an example of how synaptic plasticity results in: a. Growth processes b. Metabolic changes

Answer 1

Answer and Explanation:

Synaptic plasticity can be defined by the dynamic state capable of producing and enhancing selectively the direction and the activity of neurons in neural circuits.

Synaptic plasticity may play important roles during growth because it is a feature that has the potential to act as a feedback in order to excite and inhibit functions associated with signaling pathways. For example, it has been shown that neurotrophins modulate the synaptic plasticity, thereby controlling the growth and development of the central nervous system.

Synaptic plasticity may also be associated with metabolic changes. For example, the synaptic plasticity enables to modify those cellular preferences associated with the use of energy derived from fats and carbohydrates in the cell.
