George Trumbull Ladd 39 suggested in 1892 that the visual elements of dreams were derivations of the "psychical synthesis" of night-time retinal sense data. This hypothesis led him to speculate that the eyeballs move during dreaming. "As we look down the street of a strange city, for example, in a dream we probably focus our eyes somewhat as we should do in making the same observation when awake. . . ." Ladd's ingenious surmise went unverified until 1955 when Aserinsky and Kleitman 2 reported… Expand
Are the eye movements of dreaming sleep related to the visual images of the dreams?
TLDR
The nervous system executes a patterned output of oculomotor activity during dreaming sleep which is fairly consistent in all subjects, and it was discovered that most eye movements during REM sleep are unrelated to the action in the dream. Expand
The 'scanning hypothesis' of rapid eye movements during REM sleep: a review of the evidence.

TLDR
Directional coherence between limbs, head and eye movements during RBD suggests that, when present, REMs imitate the scanning of the dream scene, as in a virtual reality. Expand
Binocular eye movements not coordinated during REM sleep
TLDR
Binocular misalignment and disjunctive REMs during sleep suggest that separate left eye and right eye pathways generate saccades in each eye and control the position of each eye, arguing against the idea that REMs actually “track” dream images, unless each eye is watching its own dream. Expand
Dreaming in the Late Morning: Summation of REM and Diurnal Cortical Activation
TLDR
The results suggest that the major determinant of vivid visual imagery and enhanced cognitive activity during sleep is a pattern of subcortical and cortical activation that is common to both the REM phase of the REM-NREM cycle and the activated phase ofThe 24-h diurnal wake-sleep cycle. Expand
Dream research and the psychoanalytic theory of dreams.
  • H. Trosman
  • Psychology, Medicine
  • Archives of general psychiatry
  • 1963
TLDR
The recent impetus and enthusiasm for dream research began in 1953 when Aserinsky and Kleitman made an important observation while investigating electroencephalographic changes during sleep, noting the presence of eye movements which could be observed directly as well as recorded on the EEG. Expand
On Moving the Eyes to Flag Lucid Dreaming
TLDR
Despite being the most used technique to record LD, there is still no consensus regarding how to apply the PAEM in the lab, and this article will delve into the issues of recording LD through PAEM. Expand
An analysis of rapid eye movements of sleep in the monkey.
  • A. Fuchs, S. Ron
  • Psychology, Medicine
  • Electroencephalography and clinical neurophysiology
  • 1968
TLDR
Eye movements and the parietal EEG were measured in two Macaca mulatta monkeys during natural sleep suggesting that the interpretation that all eye movements during REM sleep are related to dream content should be made with caution. Expand
REM sleep eye movement counts correlate with visual imagery in dreaming: a pilot study.
TLDR
The correlation between the number of eye movements in REM sleep and visual imagery in dreaming (V) was examined and suggested that the strong EM-V association reflects a phasic, localized activation of the eye-movement-control system in association with REM sleep eye movements. Expand
Physiology and psychology of dreams.
  • A. Eiser
  • Psychology, Medicine
  • Seminars in neurology
  • 2005
TLDR
Developments in neurobiological research have established a clearer view of the functional neuroanatomy of REM sleep and dreaming, and some more recent theories of dreaming emphasize an adaptive function related to emotion and a role in learning and memory consolidation. Expand
Dreamed Movement Elicits Activation in the Sensorimotor Cortex
TLDR
It is shown here that a predefined motor task performed during dreaming elicits neuronal activation in the sensorimotor cortex, providing first evidence that specific contents of REM-associated dreaming can be visualized by neuroimaging. Expand

Cyclic variations in EEG during sleep and their relation to eye movements, body motility, and dreaming.
TLDR
Records from a large number of nights in single individuals indicated that some could maintain a very striking regularity in their sleep pattern from night to night, and that body movement, after rising to a peak, dropped sharply at the onset of rapid eye movements and rebounded abruptly as the eye movements ceased. Expand
The relation of eye movements during sleep to dream activity: an objective method for the study of dreaming.
TLDR
Testing of the relation between eye movements and dreaming found a high incidence of dream recall in Ss awakened during these periods and a low incidence when awakened at other times. Expand

TLDR
The results suggest that during natural sleep there is depression of activity in the non-specific afferent system, while activity in primary auditory pathways remains unchanged, differs in several respects from that observed during the anesthetic state. Expand

Direct Current Recordings of Eyeball Movements in Neurologic Practice
TLDR
It is imperative to utilize amplifiers capable of recording slow variational, or steady, potentials with fidelity when the rate of eyeball movement is slow or when the maintenance of a given deviation of the eyeballs is an important aspect of the study. Expand

TLDR
All animals showed many periods of a low voltage, fast (activated) EEG in the face of continued behavioral sleep as indicated by absence of muscle potentials, relaxed posture, unresponsiveness, and elevated auditory threshold. Expand
