Posted on February 17, 2019 by

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 … Continue reading →

Is the brainstem conscious?

Dogs have metacognition, maybe

Posted on December 9, 2018 by

Last year in a post on panpsychism, I introduced a hierarchy I use to conceptualize the capabilities of systems that we intuitively see as conscious.  This isn’t a new theory of consciousness or anything, just my own way of making … Continue reading →

Posted on October 28, 2018 by

I’ve had a number of conversations lately on the subject of feelings, the affective states of having valences about conscious perception, such as fear, pain, joy, hunger, etc.  Apparently a lot of people view feelings as a very mysterious phenomenon.  … Continue reading →

The prospects for a scientific understanding of consciousness

Posted on July 2, 2018 by
