A parallel framework for interactive behavior.

TL;DR: It is proposed that neural processing occurs through two waves of activation: an early wave which specifies several potential actions and a later wave of biasing influences which selects one action for execution.

Abstract: Although theoretical models often assume that the basic organization of the nervous system involves separate systems for perception, cognition, and action, neural data often does not fit into any of these conceptual categories. Here, an alternative framework is described, which focuses on interactive behavior and treats it as a continuous competition between representations of currently available potential actions. This suggests a neural organization consisting of two parallel systems: a system for action specification, which uses sensory information to represent currently available potential actions, and a system for action selection, which involves attentional and decisional mechanisms which determine the action that will be performed. It is proposed that neural processing occurs through two waves of activation: an early wave which specifies several potential actions and a later wave of biasing influences which selects one action for execution. A computational model of decision making is described within the context of this proposal, and simulations of neural and behavioral phenomena are presented.

Hidden cognitive states revealed in choice reaching tasks.
Joo-Hyun Song,Ken Nakayama +1 more
TL;DR: Continuous hand movements during target choice reaching tasks reveal the temporal evolution of hidden internal events and the direction of curved reaching trajectories elucidates the flow of earlier cognitive states into motor outputs.

Neural correlates of prior expectations of motion in the lateral intraparietal and middle temporal areas
TL;DR: The results suggest that information about an immediately upcoming stimulus does not scale the sensory response, but rather changes the amount of evidence that must be accumulated to reach a decision in areas that are involved in planning action.

Functional architectures and structured flows on manifolds: a dynamical framework for motor behavior.
TL;DR: A dynamical framework for sequential sensorimotor behavior based on the sequential composition of basic behavioral units is outlined, illustrated with a functional architecture for handwriting as proof of concept and the implications of the framework for motor control are discussed.

When the brain changes its mind: Oscillatory dynamics of conflict processing and response switching in a flanker task during alcohol challenge.
TL;DR: The results indicate that motor preparation is initiated automatically even when counterproductive but that it is monitored and regulated by the prefrontal cognitive control processes under conflict, and confirm that the regulative top-down functions are particularly vulnerable to alcohol intoxication.
Upper Limb Obstacle Avoidance Behavior in Individuals With Stroke.
Melanie C. Baniña,Aditi A. Mullick,Aditi A. Mullick,Bradford J. McFadyen,Mindy F. Levin,Mindy F. Levin +5 more
TL;DR: Deficits in higher-order motor function such as obstacle avoidance behavior may decrease actual arm use in individuals with mild-to-moderate hemiparesis and should be evaluated in routine clinical practice.
