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
Hypothalamus amygdala and septum, and is also connected with areas of the autonomous nervous system. The hypothalamus receives many inputs from the brainstem, the most notable from the nucleus of the solitary tract, the locus coeruleus, and the ventrolateral medulla. Most nerve fibres within the hypothalamus run in two ways (bidirectional). Several hypothalamic nuclei are sexually dimorphic; i.e., there are clear differences in both structure and function between males and females. Some differences are apparent even in gross neuroanatomy: most notable is the sexually dimorphic nucleus within the preoptic area, in which the differences are subtle changes in the connectivity and
