Compromised Dynamic Cerebral Autoregulation in Patients with Epilepsy

Figure 2

The autoregulatory parameter and statistical distributions in overall epileptic patients and epileptic patients with/without slow wave. (a) The autoregulatory parameter (phase difference) derived from the transfer function in overall epileptic patients. (b) Statistical distributions of the phase difference in overall epileptic patients. (c) The phase difference derived from the transfer function in epileptic patients with/without slow wave. (d) Statistical distributions of the phase difference in epileptic patients with/without slow wave. In (a) and (c), frames in orange represent specific frequency domain (0.06–0.12 Hz). In (b) and (d), bars denote means; whiskers denote standard error. for interictal slow wave patients; for slow-wave-free patients. indicates statistically different ().
