Recently, cortical correlates of specific dream contents have been reported, such as the activation of the sensorimotor cortex during dreamed hand clenching. Yet, the causal mechanisms underlying specific dream content remain largely elusive. Here, we investigated how alterations in the excitability of sensorimotor areas through transcranial direct current stimulation (tDCS) might alter dream...
Previous data suggest that the right temporo-parietal junction (rTPJ) may have a specific role in abnormal body perception (ABP), including out-of-body experience. We tested this hypothesis with inhibitory (1 Hz) and excitatory (15 Hz) repetitive transcranial magnetic stimulation (rTMS) of the rTPJ and a control site (CS, 5 cm posterior to the rTPJ along the lateral sulcus direction in Brodmann...
The neural mechanisms underlying lucid dreaming have recently been investigated using brain imaging techniques such as electroencephalography and functional magnetic resonance imaging, which produce insightful but merely correlative results. We propose that research on the neurophysiology of lucid dreaming, for instance concerning the exact relationship between the dorsolateral prefrontal...
In the last two decades considerable progress in brain imaging techniques have led to increasing interest into the neurobiology of sleep stages and dream contents. However, this fascinating research field poses several methodological challenges. The aim of this article is to discuss these challenges and to suggest novel approaches for probing the neurobiology of dream contents. Most of all, I...
