The unity of storage and processing in nervous systems

Image of Golgi stained neurons in the dentate gyrus of an epilepsy patient.

I think the brain is a computational system and what we generally refer to as the mind and consciousness are some of its computations. But I'm also aware that the brain works very differently from how a typical digital computer works. One criticism of computationalism that I have some sympathy with is the word "computation" … Continue reading The unity of storage and processing in nervous systems →

Integrated information theory as pseudoscience?

It's been an interesting week in consciousness studies. It started with Steve Fleming doing a blog post, a follow up to one he'd done earlier expressing his concerns about how the results of the adversarial collaboration between global neuronal workspace (GNW) and integrated information theory (IIT) were portrayed in the science media. GNW sees consciousness … Continue reading Integrated information theory as pseudoscience? →

Experiencing without knowing?

On Twitter, the Neuroskeptic shared a new paper, in which an Israeli team claims to have demonstrated phenomenal consciousness without access consciousness: Experiencing without knowing? Empirical evidence for phenomenal consciousness without access. A quick reminder. In the 1990s Ned Block famously made a distinction between phenomenal consciousness (p-consciousness) and access consciousness (a-consciousness). P-consciousness is conceptualized … Continue reading Experiencing without knowing? →

Workspace vs integration: results starting to come in

A few years ago it was announced that The Templeton Foundation was funding an adversarial collaboration on theories of consciousness. The initial plan was to pit Global Neuronal Workspace Theory (GNWT) against Integrated Information Theory (IIT), although the initiative plans to move on to other theories once these have been tested. Early on, I had … Continue reading Workspace vs integration: results starting to come in →

The Great Consciousness Debate: ASSC 25

This is a long video. The first hour or so features presentations on the Global Neuronal Workspace Theory by Stanislas Dehaene, Recurrent Processing Theory by Victor Lamme, Higher Order Thought Theory by Steve Fleming, and Integration Information Theory by Melanie Boly. It also has some brief recorded remarks from Anil Seth on Predictive Coding. (Fleming … Continue reading The Great Consciousness Debate: ASSC 25 →

Graziano’s non-mystical approach to consciousness

Someone called my attention to a new paper by Michael Graziano: A conceptual framework for consciousness. I've highlighted Graziano's approach and theory many times over the years. I think his Attention Schema Theory provides important insights into how top down attention works. But it's his overall approach that I find the most value in. He's … Continue reading Graziano’s non-mystical approach to consciousness →

How much can we change the causality of the brain and keep consciousness?

James of Seattle clued me in to a thought experiment described by Dr. Anna Schapiro in a Twitter thread. https://twitter.com/AnnaSchapiro/status/1512866137809195011 It's very similar to one discussed in a new preprint paper: Do action potentials cause consciousness? Like all good thought experiments, it exercises and challenges our intuitions. In this case, it forces us to contemplate … Continue reading How much can we change the causality of the brain and keep consciousness? →

Anil Seth’s theory of consciousness

I recently completed Anil Seth's new book, Being You: A New Science of Consciousness. Seth starts out discussing David Chalmers' hard problem of consciousness, as well as views like physicalism, idealism, panpsychism, and functionalism. Seth is a physicalist, but is suspicious of functionalism. Seth makes a distinction between the hard problem, which he characterizes as … Continue reading Anil Seth’s theory of consciousness →
