Information processing in the primate basal ganglia during sensory-guided and internally driven rhythmic tapping.
Gamma (γ) and beta (β) oscillations seem to play complementary functions in the cortico-basal ganglia-thalamo-cortical circuit (CBGT) during motor behavior. We investigated the time-varying changes of the putaminal spiking activity and the spectral power of local field potentials (LFPs) during a task where the rhythmic tapping of monkeys was guided by isochronous stimuli separated by a fixed du...
متن کاملReward processing in primate orbitofrontal cortex and basal ganglia.
This article reviews and interprets neuronal activities related to the expectation and delivery of reward in the primate orbitofrontal cortex, in comparison with slowly discharging neurons in the striatum (caudate, putamen and ventral striatum, including nucleus accumbens) and midbrain dopamine neurons. Orbitofrontal neurons showed three principal forms of reward-related activity during the per...
متن کاملBasal ganglia output reflects internally-specified movements
How movements are selected is a fundamental question in systems neuroscience. While many studies have elucidated the sensorimotor transformations underlying stimulus-guided movements, less is known about how internal goals - critical drivers of goal-directed behavior - guide movements. The basal ganglia are known to bias movement selection according to value, one form of internal goal. Here, we...
متن کاملReinforcement-driven dimensionality reduction--a model for information processing in the basal ganglia.
Although anatomical studies of the basal ganglia show the existence of extensive convergence and lateral inhibitory connections, physiological studies failed to show correlated neural activity or lateral interaction in these nuclei. These seemingly contradictory results could be explained with a model in which the basal ganglia reduce the dimensionality of cortical information using optimal ext...
