Basal ganglia circuits are known to have role in a wide range of behaviour spanning from movement initiation to high order cognitive processes as reward related learning. Here, the intention is to have a biophysically realistic model of basal ganglia circuit for voluntary motor action selection. The ultimate aim is to provide a framework for models which(More)
Synchronous behavior of neural populations has been related to cognitive processes as attention, learning and has been considered as hallmarks of neurological disorders. The computational models of neural structures, even the simple ones, could give informative results which can improve our understanding of cognitive processes, arising due to collective(More)
It is expected that building computational models of neural structures taking part in generating cognitive processes and emotions would not only help us understanding the brain but also give us clues to diagnose and develop treatment for neurological disorders and diseases. In this work, a computational model of cognitive task, goal directed behavior is(More)
The role of basal ganglia in motor action initiation and selection has been well studied and now it is evident that impairment in this structure causes not only causes movement disorders as Parkinson's disease, Hunting-ton's disease but also behavioral dysfunctions as addiction , obsessive-compulsive disorder [1-4]. In order to understand the mechanisms(More)
Due to the measurement techniques developed, it is now possible to observe signals at different levels in neural structures. These observations give rise to increasing works dealing with setting up the relation between such signals and cognitive processes, neurodegenerative diseases and neurobehavioral disorders. Computational neuroscience is becoming more(More)
The role of basal ganglia in motor control is well-known [1,2], but it also takes part in high order cognitive processes, such as reward-related learning, goal-directed behavior or selective attention [3-5]. The complicated and creative information processing ability of basal ganglia makes it home for decisions amongst available competitive choices.(More)
