Functional definition of an emotional system in the brain: 1 The underlying circuits are genetically predetermined to respond unconditionally to stimuli representing evolutionary pressures faced by the species 2 The circuits organize motor programs and autonomic and hormonal changes to respond to the environmental challenge or opportunity at hand 3 The circuits tune sensitivities of sensory systems to be responsive to stimuli relevant to the emotion evoked 4 The positive feedback of neural activity means emotional arousal outlasts the precipitating circumstances 5 Emotional circuits can come under cognitive control 6 Emotional circuits reciprocally influence higher decision-making and appraisal systems and consciousness 7 The circuit is capable of elaborating distinctly different subjective feelings Jaak Panksepp (1998)
