Old Brain Regions May Be Key to Consciousness, New Research Indicates

Recent research suggests that the oldest parts of the brain, such as the subcortex and even the cerebellum, may be sufficient for basic consciousness, challenging the traditional view that the neocortex is essential for conscious experience. Evidence from brain stimulation, injury, and rare cases of individuals without a neocortex indicates that consciousness might be more widespread and rooted in ancient brain structures than previously thought.
