Neural decoding

Definition

Neural decoding refers to the process of interpreting and translating the patterns of neural activity into meaningful information about external stimuli, behaviors, or cognitive states. This concept is essential for understanding how the brain processes information and how it can be used in developing brain-computer interfaces and neuroprosthetics.
