Complementary roles of basal ganglia and cerebellum in learning

Furthermore, an ever-increasing number of brain-imaging studies show that the basal ganglia and the cerebellum are involved in non-motor tasks ...

Modeling the spinal cord neural circuitry controlling cat hindlimb

The neural model of the locomotory CPG (Fig. 3a) was constructed using the hypothesis that each hindlimb is controlled by one complex CPG [10], which in turn is connected with the CPG controlling another hindlimb via a coordinating neural network. The CPG (for each hindlimb) was incorporated into th ...
