Damasio's theory of consciousness has been met with criticism for its lack of explanation regarding the generation of conscious experiences by the brain. Researchers have posited that the brain's interaction with the body alone cannot account for the complexity of conscious experience, and that additional factors must be considered.
For example, primary consciousness includes a person's experience of the blueness of the ocean, a bird's song, and the feeling of pain. Thus, primary consciousness refers to being mentally aware of things in the world in the present without any sense of past and future; it is composed of mental images bound to a time around the measurable present.
The NCC are defined to constitute the minimal set of neuronal events and mechanisms sufficient for a specific conscious percept, and consequently sufficient for consciousness. In this formalism, consciousness is viewed as a state-dependent property of some undefined complex, adaptive, and highly interconnected biological system. [3] [4] [5]
The neural correlates of consciousness (NCC) are the minimal set of neuronal events and mechanisms sufficient for the occurrence of the mental states to which they are related. [2] Neuroscientists use empirical approaches to discover neural correlates of subjective phenomena; that is, neural changes which necessarily and regularly correlate ...
Representation of consciousness from the 17th century by Robert Fludd, an English Paracelsian physician. Consciousness, at its simplest, is awareness of internal and external existence. [1] However, its nature has led to millennia of analyses, explanations, and debate by philosophers, scientists, and theologians.
While neural processes in the brain involve electrochemical interactions among neurons, the subjective experience of consciousness arises from these processes in a way that is not directly reducible to them. This emergence of conscious experience from neural substrates is a central topic in the philosophy of mind and cognitive science. [16]
While other theories assert that consciousness emerges as the complexity of the computations performed by cerebral neurons increases, [4] [5] Orch OR posits that consciousness is based on non-computable quantum processing performed by qubits formed collectively on cellular microtubules, a process significantly amplified in the neurons.
Rather than attempting to cover all the aspects of consciousness (self-awareness, thought, imagination, perception, etc.), Crick focuses on the primate visual system and breaks down the prerequisites for conscious experience into several broad subconditions, including some sort of short-term memory and attention mechanism. The book then delves ...
