Pyriform cortex

The mesolimbic from the ventral tegmentum (VTA, AlO) to the nucleus accumbens, olfactory tubercule, amygdala and pyriform cortex... 

The mesolimbic system, where the dopaminergic projections originate in the ventral tegmental area, the A10 region, and then spread to the amygdala, pyriform cortex, lateral septal nuclei and the nucleus accumbens. 

Important aspects bioassays as well as their types are discussed below. One of the main drawbacks with the bioassays is that some of them have long durations, which can delay the results. Hence, researches on new and faster bioassays are carried out. An interesting new possible bioassay involves the use of olfactory j3-waves that is, bursts of c.20 Hz fast waves that are elicited in the olfactory bulb and pyriform cortex in rats are observed.13 These fast waves are also observed in voles.14 These studies indicate that these /3-waves may provide an easy means of identifying new antifeedants in small herbivores.
