We show that while a primate chooses between two reaching actions, its motor system first represents both options and later reflects selection between them. When two potential targets appeared, many (43%) task-related, directionally tuned cells in dorsal premotor cortex (PMd) discharged if one of the targets was near their preferred direction. At the population level, this generated two simultaneous sustained directional signals corresponding to the current reach options. After a subsequent… 

Figures and Topics from this paper

Single reach plans in dorsal premotor cortex during a two-target task
TLDR
It is reported that in a delayed response task with two potential reach targets, population activity in the dorsal premotor cortex at any moment in time represents only one of the targets.
Dorsal premotor cortex is involved in switching motor plans
TLDR
These findings support the hypothesis that decisions about actions are made through a competition within the same circuits that guide the actions themselves and suggest that PMd continues to participate in action selection even when the animal changes its mind on-line.
Rapid Automatic Motor Encoding of Competing Reach Options.
TLDR
The results offer strong empirical support for theories suggesting that competing action options are automatically represented in terms of the movements required to attain them and the rapid motor encoding of potential targets may support the fast optimization of motor costs under conditions of target uncertainty.
Dorsal premotor cortex: neural correlates of reach target decisions based on a color-location matching rule and conflicting sensory evidence.
TLDR
The results indicate that PMd neurons in this task are not activated exclusively by a signal proportional to the net color bias of the DCs, and are instead initially modulated by the conflicting evidence supporting both response choices; final target selection may result from a competition between representations of the alternative choices.
Parallel specification of competing sensorimotor control policies for alternative action options
TLDR
These findings provide evidence that the brain, when presented with multiple action options, computes multiple competing sensorimotor control policies in parallel before implementing one of them.
Target Selection Signals for Arm Reaching in the Posterior Parietal Cortex
TLDR
It was found that target selection for saccade movements was only weakly represented in PRR, suggesting that PRR is involved in decision making for reach movements and that separate cortical networks exist for target selection of different types of action.

TLDR
A formal computational model is presented which demonstrates how partial specification of several potential movement directions, and the selection of the correct movement, can occur in populations of directionally tuned cells in a distributed cortical network including posterior parietal, premotor, prefrontal, and primary motor cortex.
Population dynamics of choice representation in dorsal premotor and primary motor cortex
TLDR
The representation of the DV is examined in simultaneously recorded neural populations of dorsal premotor and primary motor cortices of monkeys performing a random dots direction discrimination task with arm movements as the behavioral report to show that single-trial DVs covary with stimulus difficulty in both areas but are stronger and appear earlier in PMd compared to M1 when the stimulus duration is fixed and predictable.
Macaque dorsal premotor cortex exhibits decision-related activity only when specific stimulus-response associations are known
How deliberation on sensory cues and action selection interact in decision-related brain areas is still not well understood. Here, monkeys reached to one of two targets, whose colors alternated
Different Representations of Potential and Selected Motor Plans by Distinct Parietal Areas
TLDR
There appears to be a different flow of processing for decisions and planning for spatial target selection, which is more integrated, and nonspatial effector decisions between eye and limb movements, which are more serial.

Simultaneous encoding of multiple potential reach directions in dorsal premotor cortex.
TLDR
The results suggest that, when faced with multiple salient opportunities for reaching, the primate brain performs sensorimotor transformations in parallel to begin planning several reaching movements simultaneously before selecting one for overt execution.
Microstimulation of visual cortex affects the speed of perceptual decisions
TLDR
It is reported that in a two-alternative task, the activity of MT neurons is interpreted as evidence for one direction and against the other, and during the formation of a decision, sensory evidence for competing propositions is compared and accumulates to a decision-making threshold.
Neuronal activity in the primate prefrontal cortex in the process of motor selection based on two behavioral rules.
TLDR
The wealth of neuronal activity in the PF that seemed to play a role in motor selection was rarely seen in the primary motor cortex, and cue, delay, choice, and movement-related neuronal activity was found.
Preshaping and continuous evolution of motor cortical representations during movement preparation
TLDR
Evidence is provided for a graded preshaping of the neuronal population representation of movement direction by partial information about this parameter, and the continuous evolution of the preshaped population representation during the preparatory period towards movement initiation.
Temporal Evolution of a Decision-Making Process in Medial Premotor Cortex
TLDR
Recorded the activity of single neurons in medial premotor cortex and found that their responses correlate with the diverse stages of the discrimination process, reflecting the temporal evolution of the decision-making process leading to action selection during this perceptual task.
Prospective Coding for Objects in Primate Prefrontal Cortex
TLDR
Examination of neural activity in prefrontal (PF) cortex of monkeys performing a delayed paired associate task provides further confirmation that PF cortex does not simply buffer incoming visual inputs, but instead selectively processes information relevant to current behavioral demands, even when this information must be recalled from long-term memory.
Tuning for the orientation of spatial attention in dorsal premotor cortex
TLDR
Attentional tuning may account, at least in part, for gaze‐independent receptive fields and visuospatial, target or goal relationships in tasks involving stimulus–response incompatibility.
Monkey prefrontal neuronal activity coding the forthcoming saccade in an oculomotor delayed matching-to-sample task.
TLDR
It is suggested that PFC neurons store the direction of memory-guided saccades during a delay period before eye movement and that the same neurons may be involved in the decision-making process that underlies the selection of the saccade direction during the MC period.
Monkey primary motor and premotor cortex: single-cell activity related to prior information about direction and extent of an intended movement.
TLDR
Behavioral data support a parametric conception of motor programming, i.e., that the programming of the different movement parameters results from assembling separate processes of different duration, compatible with the model in which programming processes are serially and hierachically ordered.
The Influence of Behavioral Context on the Representation of a Perceptual Decision in Developing Oculomotor Commands
TLDR
The results suggest that formation of the decision andformation of the behavioral response share a common level of neural organization, but only when the decision is associated with a specific, predictable movement.
