The Primordial Emotions Denton distinguishes between primordial emotions, "imperious states of arousal and compelling intentions to act" (p. 7) driven by activation of interoceptors and involving ancient, lower brain regions such as the medulla, midbrain and hypothalamus, and "classic" emotions, such as anger, fear and love, driven by distance receptors (vision, hearing, olfaction) and mediated by higher, more recently evolved brain regions. The Primordial Emotions The Primordial Emotions: The Dawning of Consciousness is a 2006 book by the Australian neuroscientist Derek Denton. Denton argues that, if self-awareness and intentionality are intrinsic to consciousness, the primordial emotions such as thirst, hunger and pain (that
Cerebellum larger in reptiles, considerably larger in birds, and larger yet in mammals. The large paired and convoluted lobes found in humans are typical of mammals, but the cerebellum is, in general, a single median lobe in other groups, and is either smooth or only slightly grooved. In mammals, the neocerebellum is the major part of the cerebellum by mass, but, in other vertebrates, it is typically the spinocerebellum. The cerebellum of cartilaginous and bony fishes is extraordinarily large and complex. In at least one important respect, it differs in internal structure from the mammalian cerebellum: The fish cerebellum does not
