Computational neural network models

Definition

Computational neural network models are mathematical frameworks inspired by the structure and function of biological neural networks, designed to process information and learn from data. These models utilize layers of interconnected nodes, or artificial neurons, to perform tasks such as classification, regression, and pattern recognition. In the context of conditions like Parkinson's disease, these models can simulate and analyze the dysfunction of the basal ganglia, offering insights into potential treatment strategies and disease progression.
