Perirhinal Cortex Learns A Predictive Map of The Task Environment

WebbThe perirhinal cortex may also play a role in novelty detection, but one that differs from the hippocampal formation. Neuronal activity in the perirhinal cortex appears to register novel exposure to objects that is independent of their association with other objects or contexts (Kumaran and Maguire 2007). Moreover, there ... Webb20 juli 2011 · Further disconnection of the perirhinal and medial prefrontal cortices significantly impairs both object-in-place and temporal order memory ( Barker et al., 2007 ), showing that, depending on the nature of the recognition memory judgment, these cortical regions may function within a neural circuit.
