The basal ganglia: a vertebrate solution to the selection problem?

  title={The basal ganglia: a vertebrate solution to the selection problem?},
  author={P. Redgrave and T. Prescott and K. Gurney},
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 significant advantages for systems which incorporate a central switching mechanism. We propose that the vertebrate basal ganglia have evolved as a centralized selection device, specialized to resolve conflicts over access to limited motor and cognitive resources. Analysis of basal ganglia functional architecture… Expand

  • 2014
The basal ganglia are an interconnected circuit of foreand midbrain nuclei common to all extant vertebrates, including the lamprey, which diverged from the main vertebrate line approximately 560MYA, and it is suggested that this circuit solves the common problem of action selection. Expand
The basal ganglia as the selection mechanism in a cognitive task ∗
This paper builds on our existing, biologically constrained, model of the basal ganglia, which was originally constructed under the premise that these subcortical structures perform action selection.Expand
A basal ganglia inspired model of action selection evaluated in a robotic survival task.
A robotic implementation of a model of the basal ganglia is described and the capacity of this system to generate adaptive switching between several acts when embedded in a robot that has to "survive" in a laboratory environment is demonstrated. Expand
The Robot Basal Ganglia
A high level computational model of intrinsic basal ganglia circuitry and its interactions with simulated thalamocortical connections was implemented and exposed to the rigors of `real world’ action selection by embedding it within the control architecture of a small mobile robot. Expand
A robot model of the basal ganglia: Behavior and intrinsic processing
This work describes a robot architecture into which a computational model of the basal ganglia to generate integrated selection sequences in an autonomous agent is embedded, and demonstrates effective action selection by the embedded model under a wide range of sensory and motivational conditions.

It is shown that a standard model of action selection in a cognitive architecture (ACT-R) cannot replicate any of these findings, and an alternative solution is details that reconcilesaction selection in the architecture with the physiology of the basal ganglia, and extends the domain of application of cognitive architectures. Expand
A computational model of action selection in the basal ganglia. I. A new functional anatomy
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 is presented. Expand
The basal ganglia and action selection : a computational study at multiple levels of description.
The work presented here builds on a previous computational model of intrinsic basal ganglia processing which demonstrated that its function was consistent with a selection mechanism and emphasise the utility of modelling the same neural circuit at different levels of abstraction. Expand
The robot basal ganglia: Action selection by an embedded model of the basal ganglia
Action selection is the task of resolving conflicts between multiple sensorimotor systems seeking access to the final common motor path. Recently,1, 2 we proposed that the basal ganglia may act toExpand
Recent advances in understanding the role of the basal ganglia
A comparative overview of classic and contemporary models of basal ganglia organization and functional importance are presented, including their increased integration with cortical and cerebellar structures. Expand


Role of Basal Ganglia in Control of Innate Movements, Learned Behavior and Cognition—A Hypothesis
The progress of basal ganglia research has been rapid and fruitful. As is clear from articles in this book, we now know detailed neural circuits in the basal ganglia, heterogeneous distribution ofExpand
Parallel organization of functionally segregated circuits linking basal ganglia and cortex.
The basal ganglia serve primarily to integrate diverse inputs from the entire cerebral cortex and to "funnel" these influences, via the ventrolateral thalamus, to the motor cortex. Expand
Basal ganglia: structure and computations.
Until recently the basal ganglia of the mammalian brain have attracted little attention from theoretical neurobiologists. Traditional views of the functioning of the basal ganglia are based on theirExpand

The hypothesis states that the basal ganglia do not generate movements, and when voluntary movement is generated by cerebral cortical and cerebellar mechanisms, the basal Ganglia act broadly to inhibit competing motor mechanisms that would otherwise interfere with the desired movement. Expand
Disinhibition as a basic process in the expression of striatal functions
It is reported that the basal ganglia contribute to the initiation of movement by arousing executive motor centres via a disinhibitory mechanism and it is proposed that thebasal ganglia output is used as a movement template specifying the motor elements to be engaged in directing movement in space.

Some Perspectives on the Evolution of Intelligence and the Brain
The twin searches for animal intelligence and its neural counterparts have been dominated by a model that predicted a unilinear, hierarchical progression from simpler intellectual abilities to moreExpand
Layered Control Architectures in Robots and Vertebrates
It is argued that, in addition to subsumption- like conflict resolution mechanisms, the vertebrate nervous system employs specialized selection mechanisms located in a group of central brain structures termed the basal ganglia to provide effective and flexible action selection. Expand
The organization of the basal ganglia-thalamocortical circuits: Open interconnected rather than closed segregated
The present Commentary proposes that interaction is inherent in the neural architecture of the basal ganglia-thalamocortical circuits, and tentatively identified a motor, an associative, and a limbic split circuit, each containing a closed circuit and an open pathway. Expand

Experimental findings on reward-based learning suggest that neural activity in the striatum and substantia nigra, pars compacta changes during behavioral learning, and new evidence also suggests extreme specificity in the neural connections interrelating the basal ganglia, cerebral cortex and thalamus.
