Consciousness is an active area of both philosophical debates and scientific research.

There are two ways of looking at conscious experience: a top-down and a bottom-up approach. The top-down approach is closer to what we may call the phenomenological experience of consciousness. Some aspects of bottom-up approach explanations are from neuroscience. Most researchers present a mixture of both. Hobson (1999) supplied one of the more acceptable schemes of dimensions where consciousness can be mapped, manipulated, and explained through activation, internal–external stimulation, and modulation. Greenfield (1995) posed the question, “How exactly does nervous tissue cause consciousness?” Part of this question can be answered by looking at how the mind can emerge from the working of the brain.
