A couple of years ago, when writing about panpsychism, I introduced a five layer conception of consciousness. The idea back then was to show a couple of things. One was that very simple conceptions of consciousness, such as interactions with the environment, were missing a lot of capabilities that we intuitively think of as belonging … Continue reading Layers of consciousness, September 2019 edition

Joseph LeDoux’s theories on consciousness and emotions
In the last post, I mentioned that I was reading Joseph LeDoux's new book, The Deep History of Ourselves: The Four-Billion-Year Story of How We Got Conscious Brains. There's a lot of interesting stuff in this book. As its title implies, it starts early in evolution, providing a lot of information on early life, although … Continue reading Joseph LeDoux’s theories on consciousness and emotions
The difficulty of subjective experience
As I indicated in the Chalmers post last week, phenomenal consciousness has been on my mind lately. In the last few days, a couple of my fellow bloggers, Wyrd Smythe and James Cross, have joined in with their own posts. We've had a lot of interesting discussions. But it always comes back to the core … Continue reading The difficulty of subjective experience
Chalmers’ theory of consciousness
Ever since sharing Ned Block's talk on it, phenomenal consciousness has been on my mind. This week, I decided I needed to go back to the main spokesperson for the issue of subjective experience, David Chalmers, and his seminal paper Facing Up to the Problem of Consciousness. I have to admit I've skimmed this paper … Continue reading Chalmers’ theory of consciousness
Dehaene’s global neuronal workspace theory
I just finished reading Stanislas Dehaene's Consciousness and the Brain. Dehaene is a French psychologist and cognitive neuroscientist who is bullish on the idea of consciousness being something that can be scientifically investigated. It's an interesting book, one that I recommend for anyone interested in the science of consciousness. Dehaene accomplishes his scientific investigation by … Continue reading Dehaene’s global neuronal workspace theory
Do boiling crawfish suffer?
Recently I visited one of my cousins and, as is tradition for a lot of people this time of year, we had a crawfish boil. Eating boiled crawfish (crayfish for you non-Cajuns) is an ever present activity in southern Louisiana, at least when they're in season, and I've had my share over the years. Although … Continue reading Do boiling crawfish suffer?
The sensorium, the motorium, and the planner
I've been reading Gerhard Roth's The Long Evolution of Brains and Minds. This a technical and, unfortunately, expensive book, not one aimed at general audiences, but it has a lot of interesting concepts. A couple that Roth mentions are the terms "sensorium" and "motorium." The sensorium refers to the sum total of an organism's perceptions, … Continue reading The sensorium, the motorium, and the planner
Did smell lead to consciousness?
Smell has apparently always been a peculiar sense. The sensory pathway of smell information to the brain runs completely independent from the other senses. The pathways for the other senses run through the midbrain and thalamus and are then relayed to cortical regions. But smell goes to the olfactory bulb behind the nose, and from … Continue reading Did smell lead to consciousness?
Is the brainstem conscious?
(Warning: neuroscience weeds and references to gruesome animal research.) The vast majority of neuroscientists see consciousness as a cortical phenomenon. It may be crucially dependent on sub-cortical and sub-cerebral structures, but subjective experience itself exists mainly or entirely in the neocortex. In this view, the brainstem only produces reflex responses, with anything more sophisticated coming … Continue reading Is the brainstem conscious?
Consciousness lies in the eye of the beholder
There are few things that everyone who ponders consciousness can agree on. It's a topic where debates on the very definition of the subject are common. The only definitions that seem to command near universal assent are the ones oriented toward phenomenology, such as "subjective experience" or "something it is like." And even then, the … Continue reading Consciousness lies in the eye of the beholder
