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 thyroid hormone receptor in these neurons and affect the production of thyrotropin-releasing hormone, thereby regulating thyroid hormone production. The hypothalamus functions as a type of thermostat for the body. It sets a desired body temperature, and stimulates either heat production and retention to raise the blood temperature to a higher setting or sweating and vasodilation to cool the blood to a lower temperature. All fevers result from a raised setting in the hypothalamus; elevated body temperatures due to any other cause are classified as hyperthermia. Rarely, direct damage to the hypothalamus, such as from a stroke, will cause a fever;
