Understanding Graded Potentials: A Key Concept in Neuronal Communication

Histology anatomy-note-512-512-png-1-96x96 Tag Template - Week PRO Anatomy Note -
Graded potentials play a crucial role in the initial stages of neuronal communication, acting as temporary shifts in the membrane voltage of cells. These changes, influenced by the strength and duration of stimuli, can either depolarize or hyperpolarize the membrane, depending on the specific ion channels activated. This article explores the intricacies of graded potentials, providing a detailed breakdown of the process depicted in the accompanying image, making it an essential resource for understanding how neurons process signals.
