Journal ArticleDOI
The nucleus accumbens as a nexus between values and goals in goal-directed behavior: a review and a new hypothesis.
TL;DR: An hypothesis is proposed that aims to solve the problem of how motivational value is assigned to goals on the basis of internal states and environmental stimuli, and how this supports goal selection processes and has the potential to integrate existing interpretations of motivational value and goal selection.
Journal ArticleDOI
2009 Special Issue: Dopamine-modulated dynamic cell assemblies generated by the GABAergic striatal microcircuit
TL;DR: It is found that, with realistic in vivo background input, small assemblies of synchronised MSNs spontaneously appear, consistent with experimental observations, and that the number of assemblies and the time-scale of synchronisation is strongly dependent on the simulated concentration of dopamine.
Journal ArticleDOI
Implementing Spiking Neural Networks for Real-Time Signal-Processing and Control Applications: A Model-Validated FPGA Approach
Martin J. Pearson,Anthony G. Pipe,Ben Mitchinson,Kevin Gurney,Chris Melhuish,Ian Gilhespy,Mokhtar Nibouche +6 more
TL;DR: Two versions of a hardware processing architecture for modeling large networks of leaky-integrate-and-flre (LIF) neurons are presented; the second version provides performance enhancing features relative to the first.
Journal ArticleDOI
A New Framework for Cortico-Striatal Plasticity: Behavioural Theory Meets In Vitro Data at the Reinforcement-Action Interface
TL;DR: A computational model yields new insights into the bewildering complexity of cortico-striatal plasticity and its rationale for supporting operant learning.
Journal ArticleDOI
The role of intra-thalamic and thalamocortical circuits in action selection.
Mark D. Humphries,Kevin Gurney +1 more
TL;DR: The results are consistent with these structures having clearly defined functions in action selection by embedding it into a wider circuit containing the motor thalamocortical loop and thalamic reticular nucleus (TRN).
