چکیده
Recent studies suggest that lucid dreaming (awareness of dreaming while dreaming) might be associated with increased brain activity over frontal regions during rapid eye movement (REM) sleep. By applying transcranial direct current stimulation (tDCS), we aimed to manipulate the activation of the dorsolateral prefrontal cortex (DLPFC) during REM sleep to induce lucid dreaming. Nineteen participants spent three consecutive nights in a sleep laboratory. On the second and third nights they randomly received either 1 mA tDCS for 10 min or sham stimulation during each REM period starting with the second one. According to the participants' self-ratings, tDCS over the DLPFC during REM sleep increased lucidity in dreams. The effects, however, were not strong and found only in frequent lucid dreamers. While this indicates some preliminary support for the involvement of the DLPFC in lucid dreaming, further research, controlling for indirect effects of stimulation and including other brain regions, is needed. direct current stimulation (tDCS) tDCS effects on dream lucidity 3 Testing the involvement of the prefrontal cortex in lucid dreaming: A tDCS study

متن کاملNew perspectives for the study of lucid dreaming: From brain stimulation to philosophical theories of self-consciousness
Dreaming is often described as a state of cognitive deficiency characterized by a loss of self-reflection, orientational instability regarding persons, times, and places, deficient shortand long-term memory, and a lack of control over volition and attention (Hobson, Pace-Schott & Stickgold, 2000). On the neurophysiological level of description, a plausible correlate of such cognitive deficienci...
متن کاملEffects of left prefrontal transcranial direct current stimulation on the acquisition of contextual and cued fear memory
Objective(s): Behavioral and neuroimaging studies have shown that transcranial direct current stimulation, as a non-invasive neuromodulatory technique, beyond regional effects can modify functionally interconnected remote cortical and subcortical areas. In this study, we hypothesized that the induced changes in cortical excitability following the application of cathodal or anodal tDCS over the ...
متن کاملModulation of Drug Craving in Crystalline-Heroin Users by Transcranial Direct Current Stimulation of Dorsolateral Prefrontal Cortex
Background: Drug craving, the main cause of relapse and a major motivator for drug use, is a challenging obstacle in substance use treatment. Transcranial direct current stimulation (tDCS), a non-invasive neuromodulatory technique, has shown promising outcomes in treating different neuropsychiatric disorders such as drug addiction, more specifically on drug craving. The aim in the current study...
متن کاملMetacognitive mechanisms underlying lucid dreaming.
Lucid dreaming is a state of awareness that one is dreaming, without leaving the sleep state. Dream reports show that self-reflection and volitional control are more pronounced in lucid compared with nonlucid dreams. Mostly on these grounds, lucid dreaming has been associated with metacognition. However, the link to lucid dreaming at the neural level has not yet been explored. We sought for rel...
