Human consciousness is a human ability to be aware of their consciousness and scientifically consciousness roots in a mind, which is in the brain. The frontal cortex of the brain is highly developed and divided in three different parts. It consists of stem or medulla oblongata, cerebrum and the cerebellum.
Humans are mostly unaware of lots of thoughts which guide our living actions to keep us alive, such as seeing, breathing, touching, hearing or sometimes tasting as we do not consciously participate or think about it. Most of the purposeful behaviour of humans is done without consciousness as routine problems are dealt with unconsciously.
Consciousness is used when we want to achieve something or desire a result by alternative means and when humans alter their thought or actions from the routine, they use their consciousness. To reach consciousness people access the part of the brain which contain information, memory and emotion.
The first concept that is associated with human consciousness is the feeling of awareness and that is when we are conscious. Awareness however can be present without someone being conscious that they are aware. Thus awareness is not fully consciousness and other forms of consciousness include reasoning, free will, making choices, recalling and visual imagery.
Human consciousness cannot be separated from the human spirit, brain or mind as it is a mind’s output which in turn is in the brain. Consciousness need memory, which often can be tricky, selective, full of holes or faulty. Emotions are just as relevant to consciousness as memories.
