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 via climbing fibers. Although the inferior olive lies in the medulla oblongata and receives input from the spinal cord, brainstem and cerebral cortex, its output goes entirely to the cerebellum. A climbing fiber gives off collaterals to the deep cerebellar nuclei before entering the cerebellar cortex, where it splits into about 10 terminal branches, each of which gives input to a single Purkinje cell. In striking contrast to the 100,000-plus inputs from parallel fibers, each Purkinje cell receives input from exactly one climbing fiber; but this single fiber "climbs" the dendrites of the Purkinje cell, winding around them and making
