Objective To investigate the anatomical correlates of the neuropsychological deficits in patients with the cerebellar stroke. Methods We screened patients who were admitted to the National Rehabilitation Center with the cerebellar stroke between October 2012 and November 2016. The patients with the cerebellar stroke who underwent neuropsychological testing for which the Seoul Neuropsychological Screening Battery (SNSB) or the SNSB-II were enrolled. The neuropsychological function capacities were compared in accordance with the stroke type (hemorrhagic vs. ischemic) and the location (right/left anterior, right/left posterior intermediate, right/left posterior lateral lobe, and vermis). Mean z-scores were computed to compare the patient performances with the population averages. Results Twenty-six patients (15 with ischemic stroke and 11 with hemorrhagic stroke) with a mean age of $54.8{\pm}16.6$ years were assessed $8.8{\pm}9.2$ months after the stroke. Differences in the neuropsychological functioning according to the stroke type were not observed. All of the numerical subtests of the stroke patients showed significantly poorer performances compared with the population averages (mean z-score <0), and some of the subtests revealed abnormal performances in attention-, visuospatial function-, memory-, and frontal/executive function-related tasks (mean z-score <-1). The patients with the presence of a lesion in the right posterior intermediate lobe of the cerebellum showed a poorer performance in the subtests evaluating the executive function including the Korean-version Stroop Test (p=0.04), the Digit Symbol Coding Test (p=0.01), and the Korean-version Trail Making Test (p=0.02) compared with the patients without that lesion. Conclusion The present study confirms that the cerebellar stroke affects the neuropsychological functioning which is associated with the anatomical site of stroke.

To investigate the variation of the mandibular rest position according to time, the mandibular rest position was induced by combination of relaxation and swallowing method. The displacement of the incisal point was recorded with the pinpointed miniature lamp luminograph in three dimensions immediately, 30 seconds, and 60 seconds after induction of the mandibular rest position. The Results obtained were as follows 1. Intermaxillary vertical distance measured immediately after induction of mandibur rest position ranged from 1.0mm to 3.9mm And it varied irregularly with time, ranging from 0.1mm to 1.1mm Anteroposterior variance with time ranged irregularly from 0.2mm to 0.8mm 2. The mandibular rest position observed in the frontal plane varied with time to right or left direction, ranging from 0.2mm to 0.5mm from the centric occlusion 3. the mandibular rest position wos not placed definite position but varied spatially in certain range with time.

Using ordors with the different concentration of essential oils, e studied the effect of a pleasant olfactory stimulation on physiological responses. we examined psychological response, mental task and changes in cardiac, immunity and EEG in responses to 150times solution (feel easily) and 500times solution (feel with difficulty) which of essential oil (called PCK) were diluted in propylene glycol, and neutral (water). The 150times solution that was felt pleasant produced significant differences (p<0.05) in relative power change of beta activity in the left frontal region (Fp1, F3, F7) of the brain, and heart rate (HR) deceleration after mental task. these results are consistent with substantial research that has documented cardiac and EEG responses to pleasant stimuli. What is more, 150times solution increased the concentration of s-IgA know as an index of immunity.

Pencils are common instruments for children to use and play with. This report describes an unusual penetrating orbitocranial injury in a 5-year-old girl who was struck in her facewith a pencil. She was holding it at a desk, and her friend pushed her back. The pencil penetrated the left lower eyelid and went deep into the right frontal lobe through the base of the skull. It was removed at the emergency room, after which brain CT was performed to detect the development of an intracranial hematoma. No complications occurred after conservative management with antibiotics and an antiepileptic drug. Pencils can be hazardous to children, and a penetrating head injury with a pencil may be managed without cranial surgery.

A case of parasagittal meningioma en plaque with a peculiar clinical presentation is reported with a review of the literature. A 72-year-old woman presented with dysphasia and right hemiparesis. Computed tomography and magnetic resonance imaging demonstrated focal edema of left frontal lobe and a thick sheet-like parasagittal enhancing lesion with extension along the falx cerebri and adjacent sulcal enhancement. Differential diagnosis included idiopathic hypertrophic pachymeningitis, meningeal neurosarcoidosis, metastasis and meningioma en plaque. Cerebral angiography revealed occlusion of the anterior one-third of the superior sagittal sinus as well as a faint tumor blush supplied from the anterior branch of the middle meningeal artery. At surgery, the tumor invading the dura and skull was removed totally but the tumor invaded into the superior sagittal sinus was removed subtotally. The tumor was confirmed to be a transitional meningioma on pathological examination.

A case of chordoid meningioma occurring in a 61-year-old woman who did not have a Castleman's disease is presented. The patient had suffered from headache and motor dysphasia. Laboratory findings are normal. The tumor, located in the left frontal region and associated with peritumoral edema, was totally resected. Surgical specimen revealed a solid mass with irregular surface that measured $3.5{\times}4.5{\times}4cm$. Immunohistochemical staining revealed that the tumor cells expressed epithelial membrane antigen[EMA] focally, but not S-100 protein and glial fibrillary acid protein [GFAP], and the Ki-67 proliferative index of the tumor was 9%. The neoplasm was diagnosed chordoid meningioma of the World Health Organization[WHO] grade II. After total resection, her preoperative headache and dysphasia were disappeared.

The present study attempted to observe what changes the supply of highly concentrated(30％) oxygen cause to people's ability and cerebrum lateralization of verbal cognition, compared to air of normal oxygen concentration(21％). The experiment consisted of two runs, one for verbal cognition test with normal air(21％ of oxygen) and for verbal cognition test with more oxygen in the air(30％ of oxygen). Functional brain images were taken form 3T MRI using the single-shot EPI method. There were more activations observed at the occipital, parietal, temporal, and frontal lobes, but there were no changes in cerebrum lateralization with 30％ oxygen administration. The result of task performance showed the accuracy increased at 30％'s concentration of oxygen rather than 21％'s. It is concluded that the positive effect on the verbal cognitive performance level by the highly concentrated oxygen administration was due to changeless increase of left and right cerebrum activation.

Pleomorphic xanthoastrocytoma (PXA) has been considered as a low grade tumor of adolescents and young adults. Although this tumor often shows cystic component, the hemorrhage within the cyst is extremely rare. The authors report a rare case of cystic PXA with a hemorrhage within the cyst and the mural nodule in the left frontal lobe. A 64-year-old male presented with a week history of the right side hemiparesis. After gross total resection of the tumor, the patient was fully recovered from neurological deficit. It is suggested that this typically benign tumor could be presented with hemorrhage, causing a rapid neurological deterioration. Prompt surgical intervention, especially total removal of the tumor can provide an excellent functional recovery.

Isolated cortical vein thrombosis (ICVT) is a rare disease, accounting for less than 1% of strokes. A 46-year-old woman presented with progressive left side weakness. Magnetic resonance (MR) imaging with $T2^*$-gradient echo ($T2^*$-GE) sequence showed long cord sign at the right frontal cortex. The patient was treated with low molecular weight heparin, followed by oral warfarin for 6 months. The 3-month follow-up MR imaging showed recanalization of the previously thrombosed cortical vein. She was completely recovered without neurological deficits after 6 months. This provides that MR imaging with $T2^*$-GE sequence can help to diagnosis the ICVT and outcomes of the ICVT are generally favorable.

A 20-month-old boy presented with a intraparenchymal mass in the right frontoparietal area manifesting as complex partial seizure, secondary generalization and left hemiparesis. Magnetic resonance images (MRI) of the brain showed inhomogeneously enhancing mass in the right frontoparietal area which has irregular margin and perilesional edema. Based on the radiological findings, a preoperative diagnosis was an intraaxial tumor, such as pilocytic astrocytoma or dysembryoplastic neuroepithelial tumor. The patient underwent a surgery including frontal craniotomy. The tumor had a partially extreme adherence to the surrounding brain tissue but it showed no dural attachment. Gross-total resection of the tumor was achieved. Postoperative follow-up computed tomography scans showed no residual tumor. The pathological findings confirmed the tumor as a WHO grade I meningioma, transitional type. Nine months after the surgery, follow-up brain MRI showed no recurrence of the tumor, porencephaly in site where the tumor was resected; the patient's symptoms had fully recovered. We report the case of a meningioma in a 20-month-old boy.
