Abstract

We have investigated the effects of changes in brain temperature on the electroencephalogram (EEG) during entrance into daily torpor, a natural hypothermic state, in the Djungarian hamster. A systematic shift of single EEG frequencies was found as cortical temperature decreased. The relation between EEG frequency and cortical temperature was very similar to the temperature dependence of the Na⁺ single bond K⁺-pump, suggesting that the pump is the rate-limiting step in determining EEG frequency.

Measuring human physiological indices for thermal comfort assessment through wearable devices: A review
2021, Measurement: Journal of the International Measurement Confederation
Thermal comfort is defined as the condition of mind that expresses satisfaction with the thermal environment and it is assessed by subjective evaluation. Achieving comfortable environments is essential for human health, productivity, learning performance and energy efficiency. The measurement of thermal comfort requires an indirect process involving several domains: thermal environment, physiology and psychology. Four physiological signals were reviewed, considering their relevance in the context of measuring indoor thermal comfort. The measurement approaches for investigating electroencephalography, electrocardiograph, skin temperature and galvanic skin response signals in the field of thermal comfort are presented. This paper introduces an overview on the application of wearable sensors for recording physiological parameters and extracting features potentially correlated with thermal comfort, together with a discussion about their reliability. The review shows the state of the art, the identification of existing knowledge gaps in this area and the corresponding needs for future research and dedicated methodological efforts.
Eat, sleep, repeat: the role of the circadian system in balancing sleep–wake control with metabolic need
2020, Current Opinion in Physiology

Circadian governance over torpor expression does not exclude a close link between torpor and sleep–wake regulation. Although torpor and sleep exhibit a number of physiological and behavioural similarities [77], electrophysiologically the state of torpor cannot be robustly classified as wake or sleep state, as hypothermia itself results in altered EEG patterns [78]. In addition, evidence suggests that torpor is associated with sleep deprivation-like effects in Djungarian hamsters (Phodopus sungorus), as post-emergence NREM sleep is characterised by increased EEG SWA [79,80], although EEG waves are not entirely typical for physiological sleep after sleep deprivation [81].
Feeding and sleep are behaviours fundamental to survival, and as such are subject to powerful homeostatic control. Of course, these are mutually exclusive behaviours, and therefore require coordinated temporal organisation to ensure that both energy demands and sleep need are met. Under optimal conditions, foraging/feeding and sleep can be simply partitioned to appropriate phases of the circadian cycle so that they are in suitable alignment with the external environment. However, under conditions of negative energy balance, increased foraging activity must be balanced against sleep requirements and energy conservation. In mammals and many other species, neural circuits that regulate sleep and energy balance are intimately and reciprocally linked. Here, we examine this circuitry, discuss how homeostatic regulation and temporal patterning of sleep are modulated by altered food availability, and describe the role of circadian system in adaptation to metabolic stress.
Galanin Neurons Unite Sleep Homeostasis and α2-Adrenergic Sedation

Looking at the time course of the evoked delta power following dexmedetomidine injection (Figures 4G and 4H), in LPO-Gal-GFP mice the delta power peaked at 11 min post-injection and then declined over the following hours even though the mice were still in an NREM-like sleep. ( Because of the evolving hypothermia in the dexmedetomidine-injected LPO-Gal-GFP mice [Figure 4A], the power of the EEG spectrum declines with time as we and others documented previously; however, the vigilance state can still be scored as NREM sleep-like [22, 51].) By contrast, the delta power remained at normal NREM sleep levels in dexmedetomidine-injected LPO-ΔGal mice, even at the start of the experiment (Figures 4G and 4H). (
Our urge to sleep increases with time spent awake, until sleep becomes inescapable. The sleep following sleep deprivation is longer and deeper, with an increased power of delta (0.5–4 Hz) oscillations, a phenomenon termed sleep homeostasis [1, 2, 3, 4]. Although widely expressed genes regulate sleep homeostasis [1, 4, 5, 6, 7, 8, 9, 10] and the process is tracked by somnogens and phosphorylation [1, 3, 7, 11, 12, 13, 14], at the circuit level sleep homeostasis has remained mysterious. Previously, we found that sedation induced with α2-adrenergic agonists (e.g., dexmedetomidine) and sleep homeostasis both depend on the preoptic (PO) hypothalamus [15, 16]. Dexmedetomidine, increasingly used for long-term sedation in intensive care units [17], induces a non-rapid-eye-movement (NREM)-like sleep but with undesirable hypothermia [18, 19]. Within the PO, various neuronal subtypes (e.g., GABA/galanin and glutamate/NOS1) induce NREM sleep [20, 21, 22] and concomitant body cooling [21, 22]. This could be because NREM sleep’s restorative effects depend on lower body temperature [23, 24]. Here, we show that mice with lesioned PO galanin neurons have reduced sleep homeostasis: in the recovery sleep following sleep deprivation there is a diminished increase in delta power, and the mice catch up little on lost sleep. Furthermore, dexmedetomidine cannot induce high-power delta oscillations or sustained hypothermia. Some hours after dexmedetomidine administration to wild-type mice there is a rebound in delta power when they enter normal NREM sleep, reminiscent of emergence from torpor. This delta rebound is reduced in mice lacking PO galanin neurons. Thus, sleep homeostasis and dexmedetomidine-induced sedation require PO galanin neurons and likely share common mechanisms.
A Neuronal Hub Binding Sleep Initiation and Body Cooling in Response to a Warm External Stimulus
2018, Current Biology
Mammals, including humans, prepare for sleep by nesting and/or curling up, creating microclimates of skin warmth. To address whether external warmth induces sleep through defined circuitry, we used c-Fos-dependent activity tagging, which captures populations of activated cells and allows them to be reactivated to test their physiological role. External warming tagged two principal groups of neurons in the median preoptic (MnPO)/medial preoptic (MPO) hypothalamic area. GABA neurons located mainly in MPO produced non-rapid eye movement (NREM) sleep but no body temperature decrease. Nitrergic-glutamatergic neurons in MnPO-MPO induced both body cooling and NREM sleep. This circuitry explains how skin warming induces sleep and why the maximal rate of core body cooling positively correlates with sleep onset. Thus, the pathways that promote NREM sleep, reduced energy expenditure, and body cooling are inextricably linked, commanded by the same neurons. This implies that one function of NREM sleep is to lower brain temperature and/or conserve energy.
GABA<inf>B</inf> receptor subtypes differentially regulate thalamic spindle oscillations

We evoked thalamic oscillations by electrical stimulation of corticothalamic fibers that contact thalamic cells and selected oscillations in the frequency band of sleep spindles (Fig. 1B). Because in our slice experiments the temperature is lower than in vivo the spindle frequency range was adjusted to 5–11 Hz by applying a temperature coefficient (Q10) of 2.7 (Deboer and Tobler, 1995) to the 7–14 Hz spindle range in the intact brain. We recorded voltage signals for 15–20 min in control solution, after which we exposed the GABAB receptor contribution to spindles by adding the antagonist CGP52432 (1 μM) to the bath.
Following the discovery of GABA_B receptors by Norman Bowery and colleagues, cloning and biochemical efforts revealed that GABA_B receptors assemble multi-subunit complexes composed of principal and auxiliary subunits. The principal receptor subunits GABA_B1a, GABA_B1b and GABA_B2 form two heterodimeric GABA_B(1a,2) and GABA_B(1b,2) receptors that can associate with tetramers of auxiliary KCTD (K⁺ channel tetramerization domain) subunits. Experiments with subunit knock-out mice revealed that GABA_B(1b,2) receptors activate slow inhibitory postsynaptic currents (sIPSCs) while GABA_B(1a,2) receptors function as heteroreceptors and inhibit glutamate release. Both GABA_B(1a,2) and GABA_B(1b,2) receptors can serve as autoreceptors and inhibit GABA release. Auxiliary KCTD subunits regulate the duration of sIPSCs and scaffold effector channels at the receptor. GABA_B receptors are well known to contribute to thalamic spindle oscillations. Spindles are generated through alternating burst-firing in reciprocally connected glutamatergic thalamocortical relay (TCR) and GABAergic thalamic reticular nucleus (TRN) neurons. The available data implicate postsynaptic GABA_B receptors in TCR cells in the regulation of spindle frequency. We now used electrical or optogenetic activation of thalamic spindles and pharmacological experiments in acute slices of knock-out mice to study the impact of GABA_B(1a,2) and GABA_B(1b,2) receptors on spindle oscillations. We found that selectively GABA_B(1a,2) heteroreceptors at TCR to TRN cell synapses regulate oscillation strength, while GABA_B(1b,2) receptors control oscillation frequency. The auxiliary subunit KCTD16 influences both oscillation strength and frequency, supporting that KCTD16 regulates network activity through GABA_B(1a,2) and GABA_B(1b,2) receptors.

Identification of vagus nerve stimulation parameters affecting rat hippocampal electrophysiology without temperature effects
2020, Brain Stimulation
Recent experiments in rats have demonstrated significant effects of VNS on hippocampal excitability but were partially attributed to hypothermia, induced by the applied VNS parameters.
To allow meaningful preclinical research on the mechanisms of VNS and translation of rodent results to clinical VNS trials, we aimed to identify non-hypothermia inducing VNS parameters that significantly affect hippocampal excitability.
VNS was administered in cycles of 30 s including either 0.1, 0.16, 0.25, 0.5, 1.5, 3 or 7 s of VNS ON time (biphasic pulses, 250μs/phase, 1 mA, 30 Hz) and the effect of different VNS ON times on brain temperature was evaluated. VNS paradigms with and without hypothermia were compared for their effects on hippocampal neurophysiology in freely moving rats.
Using VNS parameters with an ON time/OFF time of up to 0.5 s/30 s did not cause hypothermia, while clear hypothermia was detected with ON times of 1.5, 3 and 7 s/30 s. Relative to SHAM VNS, the normothermic 0.5 s VNS condition significantly decreased hippocampal EEG power and changed dentate gyrus evoked potentials with an increased field excitatory postsynaptic potential slope and a decreased population spike amplitude.
VNS can be administered in freely moving rats without causing hypothermia, while profoundly affecting hippocampal neurophysiology suggestive of reduced excitability of hippocampal neurons despite increased synaptic transmission efficiency.
