Breath-holding is employed to enhance performance in sports such as diving, due to its specific physiological correlates. Its duration can be enhanced through training and specific cognitive strategies, and can be influenced by individual traits. Since hypnotizability has been linked to interoceptive sensibility and imagery abilities—both influencing breath-holding—we aimed to assess its...

Recent studies in mouse models have demonstrated that ketamine and rapastinel induce rapid-acting and sustained antidepressant effects in major depressive disorder (MDD). However, it remains unclear how ketamine's and rapastinel's opposing mechanisms of action-NMDAR antagonist and NMDAR positive allosteric modulator, respectively-result in similar antidepressant-like effects. Furthermore,...

The body ownership induced by the rubber hand illusion (RHI) has been related to a neural network involving a frontal-parietal circuit. Previous functional neuroimaging studies have demonstrated neural activation in the parietal area relative to the multisensory integration processing and to the recalibration of the felt position of body while a ventral premotor cortex activation has been...

Researchers suggest links between mind-wandering and impaired processing of external task stimuli: mind-wandering results in perceptual decoupling. The primary methodology employed to investigate the effects of mind-wandering requires people to report their conscious state and then predicts prior behavior or neurophysiological responses using the person's self-report. Unfortunately, this method...

One outstanding question in the contemplative science literature relates to the direct impact of meditation experience on the monitoring of internal states and its respective correspondence with neural activity. In particular, to what extent does meditation influence the awareness, duration and frequency of the tendency of the mind to wander. To assess the relation between mind wandering and...

Boredom is a ubiquitous human experience that can best be described as an inability to engage with one's environment despite the motivation to do so. Boredom is perceived as a negative experience and demonstrates strong associations with other negatively valenced states including depression and aggression. Although boredom has been shown to be elevated in neurological and psychiatric illnesses,...

The sense of body-ownership involves the integration of vision and somatosensation. In the rubber hand illusion (RHI), watching a rubber hand being stroked for a short time synchronously as one's own unseen hand is also stroked causes the observers to attribute the rubber hand to their own body. The RHI may elicit proprioceptive drift: The observers' sense of their own hand's location drifts...

Abstract Self-consciousness is based on multisensory signals from the body. In full-body illusion (FBI) experiments, multisensory conflict was used to induce changes in three key aspects of bodily self-consciousness (BSC): self-identification (which body ‘I’ identify with), self-location (where ‘I’ am located), and first-person perspective (from where ‘I’ experience the world; 1PP). Here, we...

The activity of voltage-gated K(+) channels (Kv) can be dynamically modulated by several events, including neurotransmitter stimulated biochemical cascades mediated by G protein-coupled receptors such as 5-HT2 receptors (5-HT2Rs). Activation of 5-HT2A/CR inhibits the Shaker-like K(+) channels Kv1.1 and Kv1.2, and this modulation involves the dual coordination of both RPTPα and distinct tyrosine...

The study of intrapsychic conflict has long been central to many key theories about the control of behavior. More recently, by focusing on the nature of conflicting processes in the brain, investigators have revealed great insights about controlled versus automatic processes and the nature of self-control. Despite these advances, many theories of cognitive control or self-control remain...

Drugs that modulate serotonin (5-HT) synaptic concentrations impact neurogenesis and hippocampal (HPC)-dependent learning. The primary objective is to determine the extent to which psilocybin (PSOP) modulates neurogenesis and thereby affects acquisition and extinction of HPC-dependent trace fear conditioning. PSOP, the 5-HT2A agonist 25I-NBMeO and the 5-HT2A/C antagonist ketanserin were...

We have previously reported that a single injection of an ultra-low dose of delta-9-tetrahydrocannabinol (THC; the psychoactive ingredient of marijuana) protected the brain from pentylenentetrazole (PTZ)-induced cognitive deficits when applied 1-7 days before or 1-3 days after the insult. In the present study we expanded the protective profile of THC by showing that it protected mice from...

Understanding the sense of agency is a key challenge for the psychological and brain sciences. When an individual makes an action that is followed by an effect such as an auditory tone, there is a perceived compression in time of the interval between the action and the effect. Since this only occurs for intentional actions, this compression is termed 'intentional binding' and has been suggested...

The scientific discovery of novel training paradigms has yielded better understanding of basic mechanisms underlying cortical plasticity, learning and development. This study is a first step in evaluating Tai Chi (TC), the Chinese slow-motion meditative exercise, as a training paradigm that, while not engaging in direct tactile stimulus training, elicits enhanced tactile acuity in long-term...

The neuronal effects of sensory events that do not enter conscious awareness have been reported in numerous pathological conditions and in normal subjects. In the present study, unconscious modulation of corticospinal excitability was probed in healthy volunteers with transcranial magnetic stimulation (TMS). TMS-induced motor evoked potentials (MEPs) were collected from the first dorsal...
