Efferent connections of the parabigeminal nucleus to the amygdala
... We recently found (Usunoff et al., 2006) that the Pbg, an established subcortical visual structure, also projects to a key structure of the limbic system, the Am. The projection from the Pbg to Am might be an element of a third disynaptic connection from the SC to the Am, since this nucleus receives ...

Hypothalamus and Limbic System
... Temperature regulation is an excellent example of a servo-control mechanism operating in the hypothalamus. The hypothalamus is sensitive both to hypothalamic and peripheral temperature, and it mediates changes in autonomic, endocrine and behavioral responses in order to maintain homeostasis. Feeding ...

How microglia kill neurons
