2002 NeuroImage  
In the present high-resolution electroencephalographic (EEG) study, we computed event-related desynchronization and synchronization (ERD/ERS) of ␣ (about 10 Hz) and ␤ (about 20 Hz) rhythms in association  ...  Finally, the pattern of hemispherical cortical rhythmicity did not support a "simple concentration" of movement observation functions in the left or right hemisphere. © 2002 Elsevier Science (USA)  ...  Fabrizio Eusebi, chairman of the Biophysics Group of Interest of the Department of Human Physiology and Pharmacology-University of Rome "La Sapienza," for his continuous support.  ...

Aim of the study. -To consider cortical oscillations at local and distant/large scale levels during the time course of motor events under both an observation and an execution condition. Methods.  ...  Data collected prior to, during, and after observation and execution of complex sequential finger movements were used to investigate these changes.  ...  Acknowledgements This study was supported by a grant from the French Ministry of Health, Youth, and Sports. The authors are grateful to the participants who participated in the study.  ...

Sensorimotor system engagement during ASL sign perception: an EEG study in deaf signers and hearing non-signers [article]

Emily Kubicek, Lorna Quandt
2019 bioRxiv   pre-print
Sensorimotor EEG responses in both Hearing and Deaf groups were sensitive to the observed gross motor characteristics of the observed signs.  ...  When a person observes someone else performing an action, the observer's sensorimotor cortex activates as if the observer is the one performing the action, a phenomenon known as action simulation.  ...  ., et al.

Characterizing hippocampal dynamics with MEG: A systematic review and evidence‐based guidelines

Emily Ruzich, Maité Crespo‐García, Sarang S. Dalal, Justin F. Schneiderman
2018 Human Brain Mapping  
The hippocampus, a hub of activity for a variety of important cognitive processes, is a target of increasing interest for researchers and clinicians.  ...  However, the decrease in MEG signal-to-noise ratio as a function of source depth implies that the utility of MEG for investigations of deeper brain structures, including the hippocampus, is less clear.  ...  Previously, Cornwell et al. (2008,b) had reported a similar effect in the left hippocampus when comparing goal-directed to aimless movements in a virtual pool.  ...

The control of consciousness

1960 Anaesthesia  
The nature of the motor responses in this case was characteristic also; instead of the laconic alternation of the other patient there was a flurried and aimless anticipatory movement, a skirmish with shadows  ...  When studies of the EEG are combined with registration of other physiological variables, particularly those associated with the auton- omic nervous system, and this medley of information is collected during  ...

The reinterpretation of dreams: an evolutionary hypothesis of the function of dreaming

A Revonsuo
2000 Behavioral and Brain Sciences  
The form and content of dreams is not random but organized and selective: during dreaming, the brain constructs a complex model of the world in which certain types of elements, when compared to waking  ...  To evaluate this hypothesis, we need to consider the original evolutionary context of dreaming and the possible traces it has left in the dream content of the present human population.  ...  , sleep), having firing rates as high as those during waking with movement. 9 Thus, motor commands are generated during REM sleep at the cortical level but they are not realized in the periphery because  ...

Control of Functional Connectivity in Cerebral Cortex by Basal Ganglia Mediated Synchronization [article]

Daniel Pouzzner
2020 arXiv   pre-print
Since the earliest electroencephalography experiments, large scale oscillations have been observed in the mammalian brain.  ...  The basal ganglia mediated synchronization model, introduced here, implicates these oscillations in the combination of cortical association mechanisms with stimulus-response and reinforcement mechanisms  ...  It seems likely that the arrangement of high resolution spatially graded feature maps, with a "rich club" topology of dense high resolution interconnections, hub areas some of which are never plastically  ...

Although there is amnesia for the period of the fugue, the individual's behaviour during this time may appear completely normal to independent observers.  ...  The presence of epileptic discharges in the EEG confirms the diagnosis, although a seizure disorder does not preclude coexisting sleepwalking.  ...  The majority of the conditions covered are given only at the three-character level, but four-character codes are given for a selection of those diagnoses that will be used most frequently.  ...
