The One

The orbital prefrontal cortex (PF) receives inputs from the olfactory, gustatory, somatosensory, visceral, and visual cortex. It is also interconnected with the amygdala which represents the current value of the resources, given the internal state of the animal. The worth of the different foods is compared in a ‘common currency’ of value. The central sector of the orbital prefrontal cortex uses vision to predict the value of the resources. These changes depend on the extent to which the animal has already become satiated on a particular food, and an interaction between the amygdala and the orbital PF cortex supports the ability to choose a new food, rather than the one on which the animal has become satiated. The lateral sector of the orbital PF cortex supports the ability to change behaviour depending on the outcome.

Premotor Areas

The dorsal prefrontal (PF) cortex generates and plans the goals or targets for foveal search and manual foraging. The goals are conditional on the relative recency of prior events and actions, and the connections of areas 9/46 and 46 explain how these areas can support the ability to generate the next goal. Area 9/46 can generate sequences of eye movements because it has visuospatial inputs from the cortex in the intraparietal sulcus and outputs to the frontal eye field and superior colliculus. Area 46 can generate sequences of hand and arm movements because it has inputs from the inferior parietal areas PFG and SII and outputs to the forelimb regions of the premotor areas and thence to the motor cortex. Both areas get timing and order information indirectly from the parietal cortex and hippocampus, and colour and shape information from the ventral prefrontal cortex. Inputs from the orbital prefrontal cortex enable both areas to integrate generate goals in accordance with current needs.
