- Research and data is rapidly evolving in the field of Consciousness study, and new non-invasive techniques are available to collect that data.
- The absence of a neocortex doesn’t prevent animals from experiencing affective states (moods or emotions).
- Artificial stimulation in animals of the same brain regions that affect emotional states of humans generate corresponding behavior and feeling states in both humans and non-humans.
- Birds in particular demonstrated a “striking case of parallel evolution of consciousness” in their behavior, neuropysiology and neuroanatomy, especially in the African grey parrot species.
- Hallucinogens have similar effects on animals to what they have on humans.
