41. A CT scan of the brain found a cerebellar pilocytic astrocytoma that was causing posterior midbrain compression. 42. It is exhibited by people with lesions or compression in the midbrain and lesions in the cerebellum. 43. The trochlear nerve then goes around the midbrain , and is visible coming out of the sides. 44. First, the retina is connected to the optic tectum by at least three types of midbrain . 45. In the embryonic mouse, Gadd45g is expressed in the neural tube, cranial and dorsal midbrain . 46. During speech production, people who stutter show overactivity in the anterior insula, cerebellum and bilateral midbrain . 47. In 1784, F�lix Vicq-d'Azyr, discovered a black colored structure in the midbrain . 48. From the spinal cord to the medulla, which then leads to the medial lemniscus of the midbrain . 49. This effect of descending inhibition can be shown by electrically stimulating the periaqueductal grey area of the midbrain . 50. The periaqueductal gray is the spine and terminate in the PAG, in the mesencephalon or midbrain ).
