Neuronal Decision-Making Circuits
Studying the neural basis of decision-making has largely taken one of two paths: one has involved cell-by-cell characterization of neuronal circuits in invertebrates; and the other, single-unit studies of monkeys performing cognitive tasks. Here I shall attempt to bring these two disparate approaches together.
متن کاملDecision Making in Recurrent Neuronal Circuits
Decision making has recently emerged as a central theme in neurophysiological studies of cognition, and experimental and computational work has led to the proposal of a cortical circuit mechanism of elemental decision computations. This mechanism depends on slow recurrent synaptic excitation balanced by fast feedback inhibition, which not only instantiates attractor states for forming categoric...
متن کاملNeuronal Correlates of Decision Making
Decision making involves selection from sets of options based on current evidence about the state of the world and estimates of the value or utility of different outcomes. The neural correlates of evidence assessment that guide simple perceptual judgments are now well understood, and we argue that this process can serve as a simple model for organizing behavioral and neural correlates of decisi...
متن کاملNeuronal adaptation effects in decision making.
Recently, there has been an increased interest on the neural mechanisms underlying perceptual decision making. However, the effect of neuronal adaptation in this context has not yet been studied. We begin our study by investigating how adaptation can bias perceptual decisions. We considered behavioral data from an experiment on high-level adaptation-related aftereffects in a perceptual decision...
متن کاملEmotion and decision making: multiple modulatory neural circuits.
Although the prevalent view of emotion and decision making is derived from the notion that there are dual systems of emotion and reason, a modulatory relationship more accurately reflects the current research in affective neuroscience and neuroeconomics. Studies show two potential mechanisms for affect's modulation of the computation of subjective value and decisions. Incidental affective state...
