11. Now it is known that not only the basal ganglia and caudate affect category learning. 12. Neurons in some parts of the caudate nucleus also show activity related to eye movements. 13. Both the amygdala and the caudate nucleus have direct and indirect projections to the hippocampus. 14. Specifically, a larger caudate nucleus volume has been linked with better verbal fluency performance. 15. The lateral prefrontal cortices, the parietal cortices and caudates were activated in both genders. 16. These include hypoplastic corpus callosum with a missing caudate nuclei bulging towards the frontal horns. 17. The prefrontal cortex, caudate nucleus, and subthalamic nucleus mediate aspects of inhibitory control. 18. The putamen and caudate nucleus are also collectively called the corpus striatum after their striped appearance. 19. The caudate nuclei are located near the center of the brain, sitting astride the thalamus. 20. Therefore, the caudate nucleus has been proven to play a role in human sleep cycles.
