The location of the global workspace

(Warning: neuroscience weeds) I've discussed global workspace theories (GWT) before, the idea that consciousness is content making it into a global workspace available to a vast array of specialty processes. More specifically, through a neural competitive process, the content excites key hub areas, which then broadcast it to the rest of the specialty systems throughout … Continue reading The location of the global workspace

Mind uploading and the philosophy of self

Diagrams showing extraction of connectome from the bain

This video does a pretty good job at outlining the idea and stark challenges with mind uploading. (Watching it isn't necessary to understand this post, unless you're completely unfamiliar with the idea. It's 14 minutes long, although the last few minutes are an advertisement.) https://www.youtube.com/watch?v=4b33NTAuF5E Kurzgesagt: Can You Upload Your Mind & Live Forever I'm … Continue reading Mind uploading and the philosophy of self

The problem with the theater of the mind metaphor

A theater in the head

In the last post, in response to my criticism of Chalmers for relying on the standard but vague "something it is like" definition of phenomenal consciousness, someone pointed out that Chalmers has talked before metaphorically about a movie playing in our head, notably at the beginning of his TED talk on consciousness. I think this … Continue reading The problem with the theater of the mind metaphor

The consciousness of crows

Last week, Science Magazine published an interesting study on bird consciousness: A neural correlate of sensory consciousness in a corvid bird.  The study conducted an experiment where crows were trained to respond to a sensory stimulus.  The stimulus itself could be at the threshold of perceptibility, above that threshold, or missing.  After the stimulus (or … Continue reading The consciousness of crows

The unproductive search for simple solutions to consciousness

(Warning: neuroscience weeds) Earlier this year I discussed Victor Lamme's theory of consciousness, that phenomenal experience is recurrent neural processing, that is, neural signalling that happens in loops, from lower layers to higher layers and back, or more broadly from region to region and back.  In his papers, Lamme notes that recurrent processing is an … Continue reading The unproductive search for simple solutions to consciousness
