'Embodied cognition' is a well established approach to cognitive psychology in which brain processing is only part (albeit an important one) of the full picture. However this video plays the sensationalist game of singling out 'the heart' as a major player in its own right
thereby alluding to ancient folk mythology about the heart being the seat of emotions. 'Unconscious' expectation reactions to events are well known to neuroscientists.
No doubt such sensationalism would appeal to the religiously/mythically inclined looking for 'time independent' or 'eternal cosmological' aspects to human cognition.
