Methods include generating at least one sleep model based, at least in part, on reference data, the at least one sleep model being configured to identify an estimated sleep age based on an input. Methods further include receiving measurement data comprising data values representing measurements of neural activity of at least one user, and generating an estimated sleep age of the at least one user based, at least in part, on the at least one sleep model and the received measurement data. Methods also include generating a plurality of stimulation parameters based, at least in part, on the estimated sleep age, the plurality of stimulation parameters being configured to modify the estimated sleep age of the at least one user. ## Claims ### Claim 1 A method comprising: generating, using one or more processors, at least one wake model based, at least in part, on reference data, the at least one wake model being configured to identify an estimated wake age of at least one user based on a measurement data;
