    • Robust spectrotemporal decomposition by iteratively reweighted least squares 

      Babadi, Behtash; Purdon, Patrick L.; Brown, Emery N.; Ba, Demba E. (National Academy of Sciences (U.S.), 2014-12)
      Classical nonparametric spectral analysis uses sliding windows to capture the dynamic nature of most real-world time series. This universally accepted approach fails to exploit the temporal continuity in the data and is ...

    • Sparse spectral estimation from point process observations 

      Miran, Sina; Purdon, Patrick L.; Babadi, Behtash; Brown, Emery Neal (Institute of Electrical and Electronics Engineers (IEEE), 2017-06)
      We consider the problem of estimating the power spectral density of the neural covariates underlying the spiking of a neuronal population. We assume the spiking of the neuronal ensemble to be described by Bernoulli statistics. ...

    • A Transition in Brain State during Propofol-Induced Unconsciousness 

      Weiner, Veronica S.; Mukamel, Eran A.; Pirondini, Elvira; Babadi, Behtash; Wong, Kin Foon Kevin; e.a. (Society for Neuroscience, 2014-01)
      Rhythmic oscillations shape cortical dynamics during active behavior, sleep, and general anesthesia. Cross-frequency phase-amplitude coupling is a prominent feature of cortical oscillations, but its role in organizing ...
