 | | The ventral visual system projects via the inferior temporal visual cortex to the amygdala and orbitofrontal cortex, which then determine using pattern association the reward or punishment value of the object, as part of the process of selecting which goal is appropriate for action. | | | For example, in the visual system it may be useful for perceptual representations or analyzers to be built which are different from each other if they are associated with different reinforcers, and for these to be less likely to be built if they have no association with reinforcement. | | | In primates, sensory analysis proceeds in the visual system as far as the inferior temporal cortex and the primary gustatory cortex; beyond these areas, for example in the amygdala and orbitofrontal cortex, the hedonic value of the stimuli, and whether they are reinforcing or are associated with reinforcement, is represented (see text). |

| | It may be, therefore, that at least lower-level gustatory neurons are plastic not necessarily to limited or enhanced experience, but are plastic primarily when there is an adaptive physiological advantage. | | | The most consistent and largest changes occur to stimuli that also impact on homeostatic systems, especially when the environmental manipulation is instituted during early development. | | | Thus, other physiological systems involved in homeostasis have important influences on plasticity of gustatory function and structure. |
