Neural Sequences Underlying Directed Turning in C. elegans
… behaviors like navigation rely on sequenced motor outputs that combine to generate effective movement. The brain-wide organization of the circuits that integrate sensory signals to select and execute appropriate motor sequences is not well understood. Here, we characterize the architecture of …

Norming of the Executive Control Battery in Children
… among raters was established on the Graphical Sequences test. Convergent validity analysis, via multiple regression, indicated that Stroop Color Word Standard Score significantly explained Graphical Sequence Errors, and WCST Perseverative Errors Scaled moderately explained Motor Sequences …

The distinct neural mechanisms underlying the production of stereotyped and exploratory vocal behavior in songbirds
… occur at the beginning and end of learning a motor skill: the initially highly variable exploratory behavior, and the ultimately stereotyped skilled performance. To understand the start and end points of learned motor behaviors, I present two studies, each on the premotor activity of ensembles …

The role of frontal cortical-basal ganglia circuits in simple and sequential visuomotor learning
… related regions of frontal cortex in visuomotor learning. Two experiments were conducted to elucidate the role of frontal cortex and striatum in visuomotor learning. Several tasks were used to characterize motor function including: a visuomotor reaction time (VSRT) task, measuring response …

Dopamine Modulates Corticostriatal Inputs During Motor Command Signalilng
Normal motor signaling in the basal ganglia requires regulating which movements to suppress and which to enact. In Parkinson's disease, loss of dopamine levels due to loss of dopaminergic neurons results in unbalanced basal ganglia output and loss of motor control. Motor sequences are thought to be …

Der Einfluss von Handlungseffekten auf den Erwerb und die Ausführung von Bewegungssequenzen
… andererseits Trainingsstudien zum Erwerb kurzer motorischer Sequenzen. In der SWR ist es die Aufgabe der Versuchspersonen, auf nacheinander dargebotene Reize so schnell wie möglich, meist mit Tastendrücken, zu reagieren. Wenn die Abfolge der Tastendrücke einer bestimmten, statistisch festgelegten …
