Emotion, memories and behaviour emerge from the coordinated activities of regions
connected by the limbic system. Here, we propose an update of the limbic model
based on the seminal work of Papez, Yakovlev and MacLean. In the revised model we
identify three distinct but partially overlapping networks: (i) the
Hippocampal-diencephalic and parahippocampal-retrosplenial network dedicated to
memory and spatial orientation; (ii) The temporo-amygdala-orbitofrontal network
for the integration of visceral sensation and emotion with semantic memory and
behaviour; (iii) the default-mode network involved in autobiographical memories
and introspective self-directed thinking. The three networks share cortical nodes
that are emerging as principal hubs in connectomic analysis. This revised network
model of the limbic system reconciles recent functional imaging findings with
anatomical accounts of clinical disorders commonly associated with limbic
pathology.
