Red Nucleus

The red nucleus is a critical structure in the CR pathway. It receives input from the interpositus, which is outputting a neural signal for driving the CR. The red nucleus then relays this signal to motor nuclei for driving the learned NM response. Lesions of the red nucleus abolish the conditioned response. It is known, however, that the red nucleus is not responsible for forming the CR because reversibly inactivating the red nucleus during training prevents the expression of the CR but does not prevent the acquisition of the CR. When the lesion is reversed (i.e., restored to normal function), CRs rapidly appear. In contrast, when the interpositus is inactivated, there is no acquisition of the CR.
