Coactivity
Coactivity refers to simultaneous activation of two or more elements within a system, occurring in response to stimuli, tasks, or social interaction. In neuroscience, coactivity is used to describe the coordinated firing or activity of neurons or brain regions within a population. Rather than focusing on single-cell responses, coactivity emphasizes ensembles, where groups of neurons participate together to encode information or drive behavior. Coactive patterns can be identified during specific tasks or spontaneous activity, and are often used to infer functional networks.
Measurement typically involves electrophysiological recordings or calcium imaging to obtain time series of activity. Analysts compute
Coactivity provides insight into how information is distributed across neural populations and how ensembles reconfigure with
Outside neuroscience, coactivity can refer to the simultaneous engagement of individuals or devices in a coordinated
