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
Anterior median fissure of the medulla oblongata Anterior median fissure of the medulla oblongata The anterior median fissure (ventral or ventromedian fissure) contains a fold of pia mater, and extends along the entire length of the medulla oblongata: It ends at the lower border of the pons in a small triangular expansion, termed the foramen cecum. Its lower part is interrupted by bundles of fibers that cross obliquely from one side to the other, and constitute the pyramidal decussation. Some fibers, termed the anterior external arcuate fibers, emerge from the fissure above this decussation and curve lateralward and upward over the surface of the medulla oblongata to
