“A glimpse of consciousness emerging in the brains of babies has been recorded for the first time. Insights gleaned from the work may aid the monitoring of babies under anaesthesia, and give a better understanding of awareness in people in vegetative states – and possibly even in animals”
What is interesting is that if the same sorts of signs can be seen in animals, then we can assume that animals also have such consciousness.
