Sleep-dependent potentiation in the visual system is at odds with the synaptic homeostasis hypothesis

Abstract

Two commentaries recently published in SLEEP came to very different conclusions regarding how data from a mouse model of sleep-dependent neural plasticity (orientation-specific response potentiation; OSRP) fit with the synaptic homeostasis hypothesis (SHY). To assess whether SHY offers an explanatory mechanism for OSRP, we present new data on how cortical neuron firing rates are modulated as a function of novel sensory experience and subsequent sleep in this model system. We carried out longitudinal extracellular recordings of single-neuron activity in the primary visual cortex across a period of novel visual experience and subsequent sleep or sleep deprivation. Spontaneous neuronal firing rates and visual responses were recorded from the same population of visual cortex neurons before control (blank screen) or novel (oriented grating) stimulus presentation, immediately after stimulus presentation, and after a period of subsequent ad lib sleep or sleep deprivation. Firing rate responses to visual stimuli were unchanged across waking experience, regardless of whether a blank screen or an oriented grating stimulus was presented. Firing rate responses to stimuli of the presented stimulus orientation were selectively enhanced across post-stimulus sleep, but these changes were blocked by sleep deprivation. Neuronal firing increased significantly across bouts of post-stimulus rapid eye movement (REM) sleep and slow wave sleep (SWS), but not across bouts of wake. The current data suggest that following novel visual experience, potentiation of a subset of V1 synapses occurs across periods of sleep. This finding cannot be explained parsimoniously by SHY. Understanding how sleep contributes to experience-dependent plasticity in the brain has important implications for human health and welfare. To promote our understanding of this process at the neuronal network and synaptic levels, we characterized the effects of sleep on a simple form of sensory-evoked plasticity in the adult mouse visual system. By quantifying the direction and magnitude of firing rate response changes in cortical neurons following novel visual experience and subsequent sleep, we have expanded upon our previous findings to provide additional evidence of synaptic potentiation during sleep. These data demonstrate that a predominant hypothesis in the field, the synaptic homeostasis hypothesis (SHY), cannot fully explain the beneficial effects of sleep on brain plasticity and cognitive function.

  • Potentiation during sleep has been observed, challenging the synaptic homeostasis hypothesis.

  • The OBH explains the fact that synaptic potentiation occurs during sleep, indicating that learning during dreams themselves leaves behind a synaptic trace.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
