Vestibular cristae ampullares of a bat and mouse showing immunolabeled calyces (special-izations of afferent neurons). Inset: isolated calyx (mad translucent) and encapsulated hair cell (scale = 5 µm). Greater density of calretinin-positive calyces in bats represent a cellular adaptation supporting highly agile behavior.

“The Anterior Cingulate Cortex in Learning and Changing Behaviour”


The dorsal anterior cingulate cortex (dACC) is one of the brain areas that has received most attention from cognitive neuroscientists using techniques from EEG to fMRI.  Activity in dACC has been linked with a variety of processes such as error detection and cognitive control.  DACC is often linked to the most sophisticated features of human behaviour even though dACC is present in many species.  Drawing on data from human and macaques I will argue that dACC can be related to basic computations that many animals including humans perform to decide whether to maintain or change their current course of action.  It carries activity relating to the average value of alternative courses of action available in the environment and it tracks how successful recent behaviour has been over multiple time scales.  This means that it can track whether current behaviour is more or less successful than it has been recently and whether a change in behaviour is likely to be more successful. Discerning such trends makes predicting the value of future behaviour possible. Time-scale specific interactions occur with representations with similar characteristics in a limited number of other brain areas.
