[How does the brain create rhythms?]

SZIRMAI Imre

[Connection was found between rhythmic cortical activity and motor control. The 10 Hz μ-rhythm and the 20-30 Hz bursts represent two functional states of the somatomotor system. A correspondence of the central μ-rhythm of the motor cortex and the physiological hand tremor (8-12 Hz) is presumed. The precise tuning of the motor system can be estimated by the frequency of repetitive finger movements. In complex tapping exercise, the index finger is the most skillful, the 3rd, 4th and 5th fingers... tovább »

[Anterior cervical fusion on the lower cervical spine: own clinical experiences]

PAZDERNYIK Szilárd, SÁNDOR László, ELEK Péter, BARZÓ Pál

[Both acute and chronic instability of the cervical spine can be succesfully treated by anterior crevical fusion. The main goal is to create a spondylodesis through which the instable motion segments are fixed in the position defined by the surgeon. The spondylodesis is realised by the bone healing of the intervertebral space. The consolidation itself is facilitated by the operative stabilisation of the segments involved, and also by the implantation/transplantation of the osteoproductive/... tovább »

[Extracellular matrix of intracerebral tumors with different invasion activity]

KLEKNER Álmos, VARGA Imre, BOGNÁR László, HUTÓCZKI Gábor, KENYERES Annamária, TÓTH Judit, HANZÉLY Zoltán, SCHOLTZ Beáta

[Objectives - Ineffective surgical and radiotherapy of glioblastoma is mainly due to its intensive infiltrating behavior. Contrarily, brain metastases of anaplastic carcinomas are well-circumscribed intracerebral lesions that can be easily exstirpated in most cases. The molecules of the extracellular matrix (ECM) play a pivotal role in the peritumoral infiltration. In this study the mRNA expression of the ECM components was investigated in two types of intracerebral malignoma with different... tovább »

[Posterior cortical atrophy (Benson-syndrome)]

RÓZSA Anikó, SZILVÁSSY Ildikó, KOVÁCS Krisztina, BOÓR Krisztina, GÁCS Gyula

[We present the characteristics of posterior cortical atrophy - a very rare cortical dementia - in a 69 year old woman’s case. Our patient’s symptoms began with a visual problem which was initially explained by ophthalmological disorder. After neurological exam visual agnosia was diagnosed apart from other cognitive disorder (alexia without agraphia, acalculia, prosopagnosia, constructional disorder, clock-time recognition disorder, dressing apraxia, visuospatial disorientation). The brain MRI... tovább »

[Molecular genetic mutation analysis in Menkes-disease with prenatal diagnosis]

LÁSZLÓ Aranka, ENDREFFY Emőke, TÜMER Zeynep, HORN Nina, SZABÓ János

[Menkes disease (MD) is an X-linked recessive multisystemic lethal, heredodegenerative disorder. Progressive neurodegeneration and connective tissue disturbances with microscopically kinky hair are the main symptoms. Molecular genetic mutation analysis was made at a Hungarian male infant suffering from MD and prenatal diagnosis was done in this MD loaded family. Method - The 12th exon of ATP7A gene has been analyzed by dideoxy-finger printing (DDF), polymerase chain reaction (PCR), direct... tovább »

[Frontotemporal dementia, Pick’s disease]

ANDREW Kertesz

[A significant expansion of knowledge in the last few years, especially in the molecular biology of frontotemporal dementia (FTD) is summarized. This condition, formerly known as Pick’s disease and considered rare, is estimated to be 12-15% of all dementias and 30-50% early onset ones. The clinical picture is protean, mainly a behavioural and language impairment, but the extrapyramidal syndromes of CBD and PSP also belong. These seemingly different presentations converge, as one or other areas... tovább »
