Soma

Definition

In the context of neuromorphic computing, soma refers to the cell body of a neuron, which contains the nucleus and is responsible for maintaining the cell's health and function. This structure is crucial for processing signals and integrating inputs from other neurons, playing a pivotal role in how artificial neural networks are designed to mimic biological systems.
