In information theory, state-dependent information is the generic name given to the family of state-dependent measures that in expectation converge to the mutual information. State-dependent informations often appear in neuroscience applications. Let X {\displaystyle X} and Y {\displaystyle Y} be random variables and y {\displaystyle y} be a state within Y {\displaystyle Y} . The state-dependent information between a random variable X {\displaystyle X} and a state Y = y {\displaystyle Y=y} is written as I ( X ; Y = y ) {\displaystyle I(X;Y=y)} . There are currently three known varieties of state-dependent information: specific-surprise, specific-information, and state-specific-information.
