Our theories stemming from perception, memory, and neurology came to similar and complementary conclusions regarding the mechanism of conscious brain processes. We suggest that consciousness is the explicit memory of past events or the general cognitive capacity to simulate events, whether used to consciously remember the past, experience the present, or imagine the future. Perceptual...
The frontal cortex plays a key role in many functions considered to be relevant for consciousness. Furthermore, altered consciousness appears to exist in those with disorders that disrupt or damage frontal areas and/or networks. This article reviews recent research discussing the impact of frontal disorders on consciousness. Many theories of consciousness have been developed over the last...
PURPOSE OF REVIEW: In this review, we summarize the current understanding of consciousness including its neuroanatomic basis. We discuss major theories of consciousness, physical exam-based and electroencephalographic metrics used to stratify levels of consciousness, and tools used to shed light on the neural correlates of the conscious experience. Lastly, we review an expanded category of...
