Kernohan's notch phenomenon in chronic subdural hematoma: MRI findings.

29 Sep 2007 We report two cases of Kernohan's notch phenomenon secondary to chronic subdural hematoma detected by MRI. In the first case, the patient was drowsy with an oculomotor palsy and a hemiparesis ipsilateral to the chronic subdural hematoma. MRI in the ... Read more...

The mesencephalic trigeminal sensory nucleus is involved in acquisition of active exploratory behavior induced by changing from a diet of exclusively milk formula to food pellets in mice.

5 Aug 2006 Post-weaning mice fed exclusively milk display low-frequency exploratory behavior [Ishii, T., Itou, T., and Nishimura, M. (2005) Life Sci. 78, 174-179] compared to mice fed a food pellet diet. This low-frequency exploratory behavior switched to ... Read more...

Lesion of the dorsorostral midbrain sparing the nigrostriatal tract mimics axial rigidity seen in progressive supranuclear palsy.

30 Jul 2005 We report on a patient with a residual dorsorostral midbrain lesion after resection of a pineal gland tumor. In addition to severe vertical gaze palsy, this patient exhibited other neurological features closely resembling progressive supranuclear ... Read more...

Technical information about 'Mesencephalon'

Definition: The middle of the three primitive cerebral vesicles of the embryonic brain. Without further subdivision, midbrain develops into a short, constricted portion connecting the PONS and the DIENCEPHALON. Midbrain contains two major parts, the dorsal TECTUM MESENCEPHALI and the ventral TEGMENTUM MESENCEPHALI, housing components of auditory, visual, and other sensorimoter systems.
