limbic system

https://doi.org/10.1351/goldbook.11852
Collection of interconnected neurons lying underneath the cerebrum on either side of the thalamus, related more by anatomical location than as a single functional entity.
Notes:
  1. Various structures of the limbic system, including the cingulate gyrus, the isthmus, the hippocampus, the uncus, and the amygdala are associated with various emotions and feelings such as anger, fear, sexual arousal, pleasure, and sadness.
  2. Often termed the paleobrain, and considered to consist of primitive structures.
