講演タイトル：
　　Determining the crucial contributions made by distinct prefrontal and medial frontal cortical regions
　　to rule-guided decision-making and cognitive control.
講演概要：
The prefrontal cortex (PFC) and anterior cingulate cortex (ACC) are commonly implicated in decision-making. Decisions can operate at many levels. For example, we can decide which item to select, or we can decide which action to make. One part of the PFC, the orbitofrontal cortex (OFC), has been closely implicated in contributing to decisions between stimuli, whereas the ACC, part of the medial frontal cortex, has been more closely implicated in contributing to decisions between actions. Yet many forms of decision-making behaviour are more complex than merely choosing between stimuli or choosing between actions and the functional dichotomy outlined above may not be as simple as this. For instance, we are also able to make decisions about which behavioural rules we will adopt. Although there have been advances in our understanding of how rules are represented in the brain, less is known about the precise contributions of the PFC and ACC to rule-based decision-making. Recent l!
esion studies in macaque monkeys in our laboratories have provided new insights into the distinct and crucial contributions that different sub-regions of PFC and ACC make to rule-guided behaviour and cognitive control.
