The mapping between neural activity and external behavioral variables can change across experimental conditions and behaviors. For example, in prefrontal cortex, the coding of a stimulus’s direction is different soon after stimulus presentation, versus during the delay period. Similarly, for a monkey performing a wrist movement task, the same linear mappings (decoders) cannot simultaneously predict movements when pushing against a spring, versus freely moving. While neural network-based decoders can have the capacity to accurately perform mappings across changing conditions, they are challengi
