The basal ganglia: a vertebrate solution to the selection problem?
A selection problem arises whenever two or more competing systems seek simultaneous access to a restricted resource. Consideration of several selection architectures suggests there are significantExpand
A computational model of action selection in the basal ganglia. I. A new functional anatomy
We present a biologically plausible model of processing intrinsic to the basal ganglia based on the computational premise that action selection is a primary role of these central brain structures. Expand
The ventral basal ganglia, a selection mechanism at the crossroads of space, strategy, and reward.
The basal ganglia are often conceptualised as three parallel domains that include all the constituent nuclei. The 'ventral domain' appears to be critical for learning flexible behaviours forExpand
A computational model of action selection in the basal ganglia. II. Analysis and simulation of behaviour
In a companion paper a new functional architecture was proposed for the basal ganglia based on the premise that these brain structures play a central role in behavioural action selection. Expand
The brainstem reticular formation is a small-world, not scale-free, network
Recently, it has been demonstrated that several complex systems may have simple graph-theoretic characterizations as so-called ‘small-world’ and ‘scale-free’ networks. These networks have also beenExpand
Is the short-latency dopamine response too short to signal reward error?
Unexpected stimuli that are behaviourally significant have the capacity to elicit a short-latency, short-duration burst of firing in mesencephalic dopaminergic neurones. An influential interpretationExpand
Feedback control in active sensing: rat exploratory whisking is modulated by environmental contact
Rats sweep their facial whiskers back and forth to generate tactile sensory information through contact with environmental structure. Expand
Layered Control Architectures in Robots and Vertebrates
We revieiv recent research in robotics, neuroscience, evolutionary neurobiology, and ethology with the aim of highlighting some points of agreement and convergence. Expand
Computational models of the basal ganglia: from robots to membranes
With the rapid accumulation of neuroscientific data comes a pressing need to develop models that can explain the computational processes performed by the basal ganglia. Relevant biologicalExpand
Active touch sensing in the rat: anticipatory and regulatory control of whisker movements during surface exploration.
Animals actively regulate the position and movement of their sensory systems to boost the quality and quantity of the sensory information they obtain. The rat vibrissal system is recognized to be anExpand
