Electroencephalography ( EEG ) and Unconsciousness
The commonest and simplest operational definition of consciousness is, the state of the patient’s awareness of self and environment and his responsiveness to external stimulation and inner need. Therefore, unconsciousness has the opposite meaning, that is, a state of unawareness of self and environment or a suspension of those mental activities by which people are made aware of themselves and t...
متن کاملAttacks of unconsciousness in association with fused cervical vertebrae.
There are more than 140 references in the Quarterly Cumulative Index Medicus to papers on fusion of cervical vertebrae, including the KlippelFeil syndrome. A particularly useful review of the Klippel-Feil syndrome is that by Erskine (1946). He wrote that 'Essential features of the cervical deformity are synostosis of two or more cervical vertebrae and flattening and widening of the vertebrae bo...
متن کاملConsciousness and unconsciousness: an EEG perspective.
At first glance, defining unconsciousness may seem easier than defining it's counterpart consciousness. Indeed, consciousness has many definitions 1 , while unconsciousness is " just " the absence of consciousness. However, the study of patients with epilepsy or severe disorders of consciousness (e.g., coma and vegetative states) or focal deficits of consciousness (e.g., blindsight) and studies...
متن کاملEEG-correlated fMRI of human alpha activity.
Electroencephalography-correlated functional magnetic resonance imaging (EEG/fMRI) can be used to identify blood oxygen level-dependent (BOLD) signal changes associated with both physiological and pathological EEG events. Here, we implemented continuous and simultaneous EEG/fMRI to identify BOLD signal changes related to spontaneous power fluctuations in the alpha rhythm (8-12 Hz), the dominant...
متن کاملAlpha-band EEG activity in perceptual learning.
In studies of perceptual learning (PL), subjects are typically highly trained across many sessions to achieve perceptual benefits on the stimuli in those tasks. There is currently significant debate regarding what sources of brain plasticity underlie these PL-based learning improvements. Here we investigate the hypothesis that PL, among other mechanisms, leads to task automaticity, especially i...
