Q
  1. Which theory posited that the hippocampus was central for the integration of sensory inputs and internal bodily environment to generate the feeling state and bodily responses associated with an emotional stimulus?
  • Peripheral feedback theory
  • Visceral brain theory
  • Cannon-Bard theory
  • Papez circuit theory
A

Correct: Visceral brian theory

Paul MacLean’s 1949 Visceral brain (later limbic system) theory posited that the hippocampus received sensory inputs from the outside world as well as information from the internal bodily environment (viscera and body wall) and that emotional experience was a function of integrating these internal and external information streams.

Incorrect:

William James’ 1890 Peripheral feedback theory state that “bodily changes follow directly the perception of the exiting fact, and that our feeling of the same changes as they occur is the emotion

Cannon and Bard believed that the brain responded to the emotional stimulus by generating both feeling state and the bodily response. Through transection experiments, they identified that the hypothalamus drove the bodily responses. They also suggested the importance of the thalamus in sensory detection, and that the cerebral cortex was probably important in the generation of the feeling state.

James Papez circuit theory was based on the anatomical connections between the hippocampus, hypothalamus, anterior thalamus and cingulate cortex. However, Papez believed that the cingulate cortex was the receptive region for the experiencing of emotion, and that the hypothalamus drove the bodily responses.
