Neuron-level granularity

Definition

Neuron-level granularity refers to the detailed representation and modeling of individual neurons within neuromorphic systems, emphasizing the unique properties and behaviors of each neuron. This concept is vital for accurately simulating neural processes and understanding how neurons contribute to overall network function. By focusing on the granularity at the neuron level, engineers can develop more biologically plausible models that enhance learning, adaptation, and information processing in artificial systems.
