Consciousness is most mysterious and debate full issue in the classical philosophy with knowledge of humanity background. From this prospect John Searle and Thomas Nagel (1998) describe three dimensions of “subjectivity”, “unity”, and “intentionality” for consciousness.
Although there are scientific techniques for understanding of two dimension of unity as well as intentionality with physical nature; lock of scientific technique for subjective nature of “subjectivity” put this idea on slippery slope. In addition there are some earlier philosophical arguments come from Daniel Dennett and neurologist John H. Jackson (1991); which count consciousness as the result of brain function rather than functioning brain.
There are tremendous efforts as well as scientific progressive evidence; to define, and explain the brain base mechanism of consciousness in neuroscience. From the neuroscience stand point consciousness is a relative awareness of each individual from him/herself in the surrounding environment at any moment. Consciousness highly depends to the brain capacity of processing as well as social context.
The consciousness involve entire nervous system rather than brain itself. Information from the surrounding environment as a physical and/or chemical stimuli changes from a physical and/or chemical energy to the electrical energy at the sensory receptors so called traducers.
The electrical current travel to brain stem; where accelerate synthesis and release of neurotransmitters to enhance processing capacity of higher levels in the brain. Limbic system evaluate the receiving information emotionally consider as either irrational or rational emotionally; passing the rational one to the thalamocortical neuronal pool.
These information in the format of electrical current pass through sensory areas, association sensory areas; then knowing area to process as a piece of receiving information from both inside the body as well as a surrounding environment. Finally recalling the classified relative information from memory storage in this regard; fulfill the process which was called consciousness.
These recalled memories have been already stored in the memory storage of the brain by the process which explained earlier.
Both social context and development play an important role in the consciousness. In due course, necessity of the neuroethic will come as an imported issue in the neuroscience and social context.
