Study Notes

What is Consciousness?

Consciousness is both the most obvious and difficult thing to study
Consciousness studies is a thriving area of study, exploring the relationship between brain activity and consciousness
The "hard problem" of consciousness asks how subjective experiences arise from objective brains
There is no universally agreed upon definition of consciousness, but several common approaches exist

Describing Consciousness

"What it's like to be..." - if there is something it is like to be for an animal, then that animal is conscious
Subjectivity or Phenomenality - Consciousness is the way things seem to me, as opposed to how they are objectively.
Qualia - The ineffable subjective qualities of experience, such as the redness of red, or the smell of turpentine

Theatre of the Mind

The common conception of consciousness is a "theatre of the mind"
Consciousness is experienced as a stream of thoughts, feelings, and perceptions
This internal theatre metaphor is challenged by the argument that the brain is a parallel, distributed processing system with no central "audience"
This raises the question of how the feeling of a unified self arises from a distributed brain

The Human Brain

The human brain is incredibly complex, with about 100 billion neurons connected by trillions of synapses
It is three times larger than it should be by comparison with other great apes
The brain and spinal cord make up the central nervous system
The cerebral cortex, the latest part of the brain to evolve, is divided into four lobes: occipital, temporal, parietal, and frontal
