What does science think about consciousness?

In summary, there is no global agreement on what consciousness is. There are various frameworks being developed, but it is still a difficult matter to study.

I have the be careful because I don't want this topic to be about philosophy. I want to know what science thinks about consciousness. Is there a global agreement on what it might be? A physical thing like a gene or is it linked in with dna?

There must be some kind of scientific view on what it could or is likely to be. Please only reply if you're professionally qualified to do so. I don't want philosophical answers that will get the thread closed.

This is/was a "fringe" refereed paper:
Neurophenomenology Integrating Subjective Experience and Brain Dynamics in the Neuroscience of Consciousness
Authors: Lutz, Antoine1; Thompson, E.
Journal of Consciousness Studies, Volume 10, Numbers 9-10, 2003 , pp. 31-52(22)
This area of Neuroscience is not hard science. IMO, I liken it to the way Psychology was a long while back. It is hard to get a lot of rigor in the subject.

If you take a class on the history of science, you will encounter something like the following model:
Alpha science - purely descriptive ---> Omega science is highly predictive, has theories and models that are proven to work in the real world and in applied science, and predicts relations between disparate fields that were not previously recognized. Obviously there are beta, gamma steps and so on down the spectrum.

The best I can give Consciousness studies is that it is a beginning alpha science: Like Linnaeus was doing, in the early 1700's, putting things into cubby holes so they have a common reference - basic descriptive science.

You can google for 'neuroscience consciousness' and look around. The JCS is now defunct.

I am not a psychologist, surely some will not have a view like mine. I was trained as a biologist. So I'm a "harder" science guy looking at a "softer" science.

If you don't know Linnaeus, you should:

Exact sciences are largely about mechanisms and their mathematical analysis. When applied to human, science traditionally views it as a machine, so there is no obvious place or meaning for "consciousness". Most scientists do not think about this concept in terms of science.

There may be some attempts to model thinking process in scientific way, perhaps similar to what is studied in the subject "artificial intelligence".

Meanwhile, "consciousness" is a difficult matter that can be perhaps better studied by other disciplines, perhaps psychology or philosophy.

No. There's no global agreement. There's not even really conclusive evidence to agree on. There are some frameworks being developed, though:

Varela's "brainweb":

Christof Koch's "framework for consciousness"
http://codatest4.library.caltech.edu/26/1/438.pdf[/URL]

Friston's "free energy principle":

The real test would be able to alter the conscious experience in a reliable way. Currently, we can alter consciousness with drugs, but they're not reliable. They affect the system in unpredictable ways and affect different people differently.

I thought to resurrect this old thread briefly as it seems the only PF thread that touches in any contextual manner upon the work by Professor Michael Graziano of Princeton. I came across his work while reviewing a bunch of papers and studies addressing Libet's earlier experimental data and how that kind of experience is viewed today.

So far in my reading I've barely scratched the surface of modern neuroscience and its explanatory power for the experience of 'consciousness', but Graziano's "Attention Schema Theory" has a certain intuitive ring of authenticity.

I wonder if anyone has read his work and can offer an opinion? I have bought his book and am halfway through it, plus I've read several of his articles and papers and to me it has some nice features, not the least of which is a simplicity of concept. My own thoughts on the matter are that as consciousness must arise from the evolution of the processing capabilities of the brain then the underlying process must be relatively simple (and in fact present from the earliest organisms in form if not function).

This Frontiers in Psychology paper has a useful overview plus some comparison with other research.

Necropost closed for Moderation...

This old thread is too philosophical for the new PF rules, so it will stay closed.

1. What is consciousness according to science?

Consciousness is a state of awareness and the ability to experience sensations, thoughts, and emotions. In science, it is often described as the product of complex neural activity in the brain.

2. Can consciousness be scientifically studied?

Yes, science has been studying consciousness through various fields such as neuroscience, cognitive psychology, and philosophy. However, it is still a complex and ongoing area of research with many unanswered questions.

3. Is consciousness a purely biological phenomenon?

While consciousness is believed to be closely tied to brain activity, there are ongoing discussions and debates about the role of consciousness in the larger universe and whether it can exist outside of biological beings.

4. How does science explain the subjective experience of consciousness?

There is no consensus among scientists on how to fully explain the subjective experience of consciousness. Some theories suggest that it is an emergent property of complex brain activity, while others propose that it is a fundamental aspect of the universe.

5. Can science ultimately solve the mystery of consciousness?

It is a complex and ongoing area of research, so it is difficult to say for certain. However, through continued advancements in technology and interdisciplinary approaches, science may be able to uncover more about the nature of consciousness and how it arises in the brain.
