TSC and Typical Development parameterized power spectra. TSC and TD groups showed significantly different resting power in several frequency ranges, denoted by an asterisk and black bar spanning the significant frequency range. In aperiodic power (middle row), the TSC group showed significantly greater broadband nonscillatory neuronal firing than the TD group in the posterior intercept, denoted by an asterisk. No group differences were observed in the slope, which reflects the excitatory-inhibitory balance
