Levels of consciousness

In studies of disorders of consciousness in humans, the idea of ‘levels of consciousness’ has been influential [8]. Clinicians assessing patients with disorders of consciousness assign a level of consciousness, with coma at one end of the scale, conscious wakefulness at the other, and various intermediate grades (such as deep sleep and light sleep) in between. It is tempting to apply this to non-human animals. We could attempt to construct a single sliding scale of animal consciousness, along which birds (such as corvids), fish, cephalopods (such as octopuses), bees, and so on could all be placed.Dimensions of Animal Consciousness Jonathan Birch @ Alexandra K.
