The rodent orbitofrontal cortex

The rodent appears to have only agranular orbitofrontal, and not most of the parts present in primates including humans. In addition, many of the pathways involved in reward processing, including the taste pathways, are differently organized in rodents, with less emphasis on processing to the object level before the orbitofrontal cortex, and then reward value representations especially in the orbitofrontal cortex. For these reasons, a separate chapter is devoted to the rodent orbitofrontal cortex.
