Neural correlates of decision variables in parietal cortex

  author={Michael Louis Platt and Paul W. Glimcher},
Decision theory proposes that humans and animals decide what to do in a given situation by assessing the relative value of each possible response. This assessment can be computed, in part, from the probability that each action will result in a gain and the magnitude of the gain expected. Here we show that the gain (or reward) a monkey can expect to realize from an eye-movement response modulates the activity of neurons in the lateral intraparietal area, an area of primate cortex that is thought… 

Neuronal Processing of Economic Value in Orbitofrontal Cortex

Data is presented indicating that individual neurons in orbitofrontal cortex (OFC) process economic value in abstract, independently of the sensory stimulus and the motor response, and neurons in OFC are a good candidate substrate for value assignment during economic choice.

A general mechanism for perceptual decision-making in the human brain

Functional magnetic resonance imaging and a categorization task show that even for complex object categories, the comparison of the outputs of different pools of selectively tuned neurons could be a general mechanism by which the human brain computes perceptual decisions.

Neural computations underlying action-based decision making in the human brain

Using fMRI in human subjects, evidence is found for action-value signals in supplementary motor cortex and signals in the dorsomedial frontal cortex that resemble the output of a decision comparator, which implicates this region in the computation of the decision itself.

A neural correlate of response bias in monkey caudate nucleus

This work identifies neurons in the monkey caudate nucleus that create a spatially selective response bias depending on the expected gain, and concludes that this neuronal mechanism creates an advance bias that favours a spatial response when it is associated with a high reward value.

Representation of Confidence Associated with a Decision by Neurons in the Parietal Cortex

It is shown that the same neurons that represent formation of a decision encode certainty about the decision, which in humans would be described as the degree of confidence in one's decision.

A review of recent studies of visual-saccadic decision making, a system that is becoming a model for understanding decision making in general, that examine the neural basis of decisions, ranging from those made in predictable sensorimotor tasks to those unpredictable decisions made when animals are engaged in strategic conflict.

Orbitofrontal Cortex: A Neural Circuit for Economic Decisions

Distinct Representations of a Perceptual Decision and the Associated Oculomotor Plan in the Monkey Lateral Intraparietal Area

The results suggest that perceptual decision-making and action selection are different brain processes that only appear to be inseparable under particular behavioral contexts.

An initial study of neural responses in the lateral intraparietal area (LIP) of the cerebral cortex while alert monkeys discriminated the direction of motion in a visual display finds signals that appear to reflect integration of sensory signals toward a decision appropriate for guiding movement.

Coding of intention in the posterior parietal cortex

It is concluded that the posterior parietal cortex contains signals related to what the animal intends to do, and activity before the movement depended on the type of movement being planned.

Motor intention activity in the macaque's lateral intraparietal area. II. Changes of motor plan.

This result predicts that, should be monkey change his intention of what the next saccade will be, LIP activity should change accordingly to reflect the new plan, and this prediction was tested by training monkeys to change their saccadic plan on command and recording the activity of LIP neurons across plan changes.

Responses of intraparietal neurons to saccadic targets and visual distractors.

Activity in the population of intraparietal neurons was found to be independent of distractor relevance, suggesting that LIP neuronal activation represents saccadic targets and, at a lower level of activity, visual distractors, but does not encode the relevance of distracting stimuli on these tasks.

Motor intention activity in the macaque's lateral intraparietal area. I. Dissociation of motor plan from sensory memory.

This study examined whether the M activity of LIP neurons specifically encodes movement intention or the locations of recent visual stimuli, or a combination of both, and investigated whether the intended-movement activity reflects changes in motor plan.

The representation of visual salience in monkey parietal cortex

The results show that under ordinary circumstances the entire visual world is only weakly represented in LIP, with only the most salient or behaviourally relevant objects being strongly represented.

Saccadic Probability Influences Motor Preparation Signals and Time to Saccadic Initiation

This study demonstrates how situational experience can expedite motor behavior via the advanced preparation of motor programs via theAdvanced planning of a movement toward an upcoming target whose location is gathered via environmental cues or situational experience.

Movement selection in advance of action in the superior colliculus

The results suggest that the superior colliculus participates in the process of saccade selection, and shows that prelude activity occurs shortly after information is available for correct saccades selection and, more importantly, the activity is predictive of sAccade choice.

Dissociation Of Working Memory from Decision Making within the Human Prefrontal Cortex

A cognitive and anatomic double dissociation between deficits in decision making (anterior VM) and working memory (right DL/M) is revealed, the first direct evidence of such effects in humans using the lesion method and underscores the special importance of the VM prefrontal region in decisionMaking, independent of a direct role in working memory.

Neural basis of saccade target selection in frontal eye field during visual search

This work investigated target selection in rhesus monkeys performing a visual search task by recording neurons in the frontal eye field, an area known to be responsible for generating purposive eye movements, and found that the initial visual responses to search stimulus arrays were the same whether the target or a distraction was in the response field.
