“…In epileptic patients, direct intracerebral recordings in the striate cortex showed monophasic or diphasic potentials during PS, isolated or in bursts (Salzarulo et al, 1975). The finding was corroborated in normal subjects by surface electroencephalography (EEG) showing transient occipital and/or parietal potentials time-locked to REMs .…”

“…Potentially important functional roles have been attributed to these waves, including the promotion of brain development and the facilitation of brain plasticity (Datta, 1999). Several lines of evidence suggest the existence of PGO waves in humans: direct intracranial recordings in epileptic patients (Salzarule et al, 1975), surface EEG (Salzarule et al, 1975), magnetoencephalography (MEG) (Inoue, Saha, & Musha, 1999). Neuroimaging studies using PET and fMRI also found correlations during REM sleep, but not during wakefulness, between spontaneous eye movements and regional cerebral blood flow (rCBF) in the occipital cortex and the lateral geniculate of the thalamus (Peigneux et al, 2001;Wehrle et al, 2005;Miyauchi et al, 2009).…”

a b s t r a c tDream is a state of consciousness characterized by internally-generated sensory, cognitive and emotional experiences occurring during sleep. Dream reports tend to be particularly abundant, with complex, emotional, and perceptually vivid experiences after awakenings from rapid eye movement (REM) sleep. This is why our current knowledge of the cerebral correlates of dreaming, mainly derives from studies of REM sleep. Neuroimaging results show that REM sleep is characterized by a specific pattern of regional brain activity. We demonstrate that this heterogeneous distribution of brain activity during sleep explains many typical features in dreams. Reciprocally, specific dream characteristics suggest the activation of selective brain regions during sleep. Such an integration of neuroimaging data of human sleep, mental imagery, and the content of dreams is critical for current models of dreaming; it also provides neurobiological support for an implication of sleep and dreaming in some important functions such as emotional regulation.

“…It is thought that PGO waves are related to several important brain functions such as sensorimotor integration, dreaming, learning, development of the visual system and so on (Callaway et al 1987;Marks et al 1995;Datta 2000). Although the existence of PGO waves in humans has been suggested by several studies based on direct depth recordings (Salzarulo et al 1975;Lim et al 2007), MEG (Ioannides et al 2004), PET (Peigneux et al 2001), and fMRI (Wehrle et al 2005), there is a need for higher spatial and temporal resolution measurements to elucidate the cortical-subcortical functional neuroanatomy of PGO waves.…”

To identify the neural substrate of rapid eye movements (REMs) during REM sleep in humans, we conducted simultaneous functional magnetic resonance imaging (fMRI) and polysomnographic recording during REM sleep. Event-related fMRI analysis time-locked to the occurrence of REMs revealed that the pontine tegmentum, ventroposterior thalamus, primary visual cortex, putamen and limbic areas (the anterior cingulate, parahippocampal gyrus and amygdala) were activated in association with REMs. A control experiment during which subjects made self-paced saccades in total darkness showed no activation in the visual cortex. The REM-related activation of the primary visual cortex without visual input from the retina provides neural evidence for the existence of human pontogeniculo-occipital waves (PGO waves) and a link between REMs and dreaming. Furthermore, the time-course analysis of blood oxygenation level-dependent responses indicated that the activation of the pontine tegmentum, ventroposterior thalamus and primary visual cortex started before the occurrence of REMs. On the other hand, the activation of the putamen and limbic areas accompanied REMs. The activation of the parahippocampal gyrus and amygdala simultaneously with REMs suggests that REMs and/or their generating mechanism are not merely an epiphenomenon of PGO waves, but may be linked to the triggering activation of these areas.
