Participants with intracranial electrodes listened to two competing, spatially separated conversations. Their neural signals were recorded and fed into a real-time processing system. The system uses a linear regression model to reconstruct the temporal envelope of the attended speech from low-frequency (LF) and high-gamma (HF) neural features. The reconstructed envelope is then compared to the envelopes of the two conversations to determine the listener’s focus, which in turn drives the selective amplification of the attended speaker.

Sleep is known to promote tissue growth and regulate metabolism, partly by enhancing growth hormone (GH) release, but the underlying circuit mechanism is unknown. Ding et al. demonstrate how GH release, which is enhanced during both rapid eye movement (REM) and non-REM (NREM) sleep, is regulated by sleep-wake-dependent activity of distinct hypothalamic neurons expressing GH-releasing hormone (GHRH) and somatostatin (SST). SST neurons in the arcuate nucleus suppress GH release by inhibiting nearby GHRH neurons that stimulate GH release, whereas periventricular SST neurons inhibit GH release by projecting to the median eminence. GH release is associated with strong surges of both GHRH and SST activity during REM sleep but moderately increased GHRH and decreased SST activity during NREM sleep. Furthermore, Ding et al. identified a negative feedback pathway in which GH enhances the excitability of locus coeruleus neurons and increases wakefulness.
