Genesis

Definition

In a scientific context, genesis refers to the origin or process of formation of a particular phenomenon or structure. This term is often used to describe the developmental processes that lead to specific biological functions or structures, particularly in neural and physiological contexts. Understanding genesis helps in exploring how neurons and their connections form and evolve, which is critical for models that describe their electrical activity and behavior.
