Associative encoding in anterior piriform cortex versus orbitofrontal cortex during odor discrimination and reversal learning.
Recent proposals have conceptualized piriform cortex as an association cortex, capable of integrating incoming olfactory information with descending input from higher order associative regions such as orbitofrontal cortex (OFC). If true, encoding in piriform cortex should reflect associative features prominent in these areas during associative learning involving olfactory cues. To test this hyp...

Recent proposals have conceptualized piriform cortex as an association cortex, capable of integrating incoming olfactory information with descending input from higher order associative regions such as orbitofrontal cortex and basolateral amygdala (ABL).

متن کاملOrbitofrontal Cortex, Associative Learning, and Expectancies
Orbitofrontal cortex is characterized by its unique pattern of connections with subcortical areas, such as basolateral amygdala. Here we distinguish between the critical role of these areas in associative learning and the pivotal contribution of OFC to the manipulation of this information to control behavior. This contribution reflects the ability of OFC to signal the desirability of expected o...
متن کاملOdor-intensity coding in the anterior piriform cortex.
The primary olfactory cortex is defined as the region that receives direct fiber projection from the olfactory bulb (OB). The piriform cortex (PC) is the largest structure in the olfactory cortex. However, no ‘point to point’ anatomical connection between the OB and PC has been found (Haberly, 1998). In addition, no evidence that neurons with similar odorant preferences are located in a cluster...
متن کاملOdor specificity of habituation in the rat anterior piriform cortex.
Exposure to odorants results in a rapid (<10 s) reduction in odor-evoked activity in the rat piriform cortex despite relatively maintained afferent input from olfactory bulb mitral cells. To further understand this form of cortical plasticity, a detailed analysis of its odor specificity was performed. Habituation of odor responses in anterior piriform cortex single units was examined in anesthe...
