Aesthetic chills, psychogenic shivers elicited by emotionally charged stimuli such as music, offer a neurophysiological marker bridging subjective experience and measurable physiology. Although neuroimaging has localized chills to reward and interoceptive circuits and behavioral work has linked them to prosocial outcomes, their electrophysiological signature and its relationship to...
Floatation-REST (Reduced Environmental Stimulation Therapy) systematically alters sensory and bodily input by combining neutral buoyancy, thermal and proprioceptive neutrality, attenuation of exteroceptive stimulation, and enhancement of cardiorespiratory signaling to the brain. Here we examined whether this non-pharmacological sensory perturbation induces altered states of consciousness and...
Abstract In this randomized, controlled, and double-blind experiment with a relatively large sample (n = 262), a novel technique of audiovisual stimulation (AVS) was demonstrated to substantially improve self-reported mood states by reducing several negative affects, including anxiety and depression, and enhancing performance on mood-sensitive cognitive tasks. Most of the AVS effects were...
Abstract: Abundant evidence from slow wave sleep, anesthesia, coma, and epileptic seizures links high-voltage, slow electroencephalogram (EEG) activity to loss of consciousness. This well-established correlation is challenged by the observation that children with Angelman syndrome (AS), while fully awake and displaying volitional behavior, display a hypersynchronous delta (1–4 Hz) frequency EEG...
Numerous theories link consciousness to informationally rich, complex neural dynamics. This idea is challenged by the observation that children with Angelman syndrome (AS), while fully conscious, display a hypersynchronous electroencephalogram (EEG) phenotype typical of information-poor dynamics associated with unconsciousness. If informational complexity theories are correct, then sufficiently...
