Neural encoding

Definition

Neural encoding is the process by which information is represented in the brain by neural activity. This involves the transformation of sensory input into patterns of electrical signals among neurons, allowing the brain to process and interpret information from the environment. Understanding neural encoding is crucial for developing neuromorphic and bio-inspired computing systems that mimic biological processes.
