Study reveals altered brain dynamics in those with unresponsive arousal syndrome, previously known as "vegetative state", and in those with minimally conscious state.
Consciousness can not simply be reduced to neural activity alone, researchers say. A novel study reports the dynamics of consciousness may be understood by a newly developed conceptual and mathematical framework.
Brain mapping study identifies important neural networks and their connections that appear to enhance the conscious experience.
During sleep, the brain analyzes auditory input but is unable to focus on the sound or identify the noise; therefore no conscious awareness of the stimuli occurs.
Some neurons in the cerebral cortex show higher spontaneous activity during general anesthesia than when awake, and this activity is synchronized across the cortical cells.
New findings reveal how anesthesia-induced unconsciousness differs from normal sleep in relation to delta wave activity in the brain.
The perceptual accuracy of visual information and its subjective interpretation use separate neural mechanisms that can be manipulated independently of each other.
