Pathophysiologische Veränderungen spezifischer neurofunktioneller Systeme bei Schizophrenie
(2021-04-06)Schizophrenia is a frequent psychiatric disease with a heterogeneous clinical appearance involving a dysfunction of reward processing. In the present work schizophrenic patients and matched control subjectcs were investigated ... -
Beeinträchtigungen der Arbeitsgedächtnisleistung bei Patienten mit Schizophrenie. Eine Replikationsstudie unter Verwendung einer Normierungsstichprobe
(2016-09-09)Working memory deficits are core findings in patients with schizophrenia. But until now there is not a study that shows those impairments in comparison to a norm sample. We generated sex-, age- and education-dependent ... -
Sprachlateralisierung bei Epilepsiepatienten: Ein Vergleich der Ergebnisse funktioneller Magnetresonanztomografie (BOLD MRT) mit denen der Diffusionstensorbildgebung (DTI)
(2014-01-09)To assess whether functional language lateralisation mirrors structural white matter asymmetry, two non-invasive in vivo MRI-methods were acquired. The results of a group of patients with temporal lobe epilepsy and a group ... -
Innovative MRT-Kontraste zur in-vivo-Differenzierung von Patienten mit typischem idiopathischen Parkinson und atypischen Parkinsonsyndromen
(2013-12-19)BACKGROUND AND PURPOSE: In 20% of the cases, "atypical" parkinsonian syndromes (APS) can be distinguished from typical idiopathic Parkinson's syndrome (IPS). In addition to extra symptoms and a more progressive course ... -
Sprachlateralisierung bei Patienten mit idiopathischem Stottern und bei gesunden Probanden: Ein Vergleich der Ergebnisse funktioneller Magnetresonanztomografie mit denen der Diffusionstensorbildgebung
(2013-12-10)So far the reason for persistent developmental stuttering is still unclear. Typically the speech disorder starts in preschool age. Approximately 1% of adults are stuttering. One of the aims of this study was it to investigate ... -
Interindividuelle Unterschiede der Impulsivität und Impulskontrolle
(2013-04-04)In the present study I used functional magnetic resonance imaging to assess the neural mechanisms who allow people to resist immediate rewards to achieve a superordinate long-term goal. Low and high extreme impulsivity ... -
Die Wirkung des BDNF-Polymorphismus auf trankraniell induzierte Neuroplastizität
(2013-02-04)The thesis examines the effects of the BDNF polymorphism on the neuroplasticity, wich can be influenced by various electrical flow and magnetic stimulation methods -
Eine Voxel-basierte morphometrische Untersuchung der Effekte von Suszeptibilitätsgenen der Schizophrenie auf hirnregionale Volumina der grauen Substanz
(2012-09-28)The etiology of schizophrenia and other psychiatric disorders is characterized by a strong genetic influence which was confirmed in family, twin and adoption studies. Within genome wide coupling and association studies ... -
Untersuchung der Effekte einer EPO-Therapie auf die kortikale Atrophie bei chronisch-schizophrenen Patienten - eine MRT-volumetrische Studie
(2012-07-11)This double-blind randomized multicenter trial tries to evaluate the influence of a high-dose intravenous therapy of erythropotin (EPO) for a 12 weeks period of time on the brain tissues within 32 male schizophrenic patients. ... -
Decis-State: Einfluss des Sättigungsgrades auf das Entscheidungsverhalten und die funktionelle Interaktion neuronaler Systeme - Eine fMRT-Studie
(2012-06-26)Obesity is one of the most pressing issues in modern medicine. Previous studies indicated that food images activate distinct brain areas such as the nucleus accumbens (Nacc), ventral tegmental Area (VTA), orbitofrontal ... -
Verarbeitung des relativen Belohnungswertes im menschlichen Gehirn. Eine Metaanalyse hirnbildgebender Studien.
(2012-02-06)In human life rewards function as an incentive for goal-directed behaviour and contribute amongst others to learning and optimising behaviour. By functional imaging using fmri and pet, ... -
Untersuchungen des visuellen Kortex zum Mechanismus der visuellen Fusion mittels funktioneller Magnetresonanztomographie
(2011-07-18)Visual fusion is a fundamental element of normal binocular vision. Without visual fusion adverse effects as diplopia appear. In current research the neuronal background of visual fusion is ... -
Die Kraft der Einbildung. Wie mentales Imagery die Wahrnehmung ängstlicher Gesichter verändert. Eine fMRT-Studie.
(2011-03-03)Our expectancies strongly shape our perception of the world. Sometimes preconceptions about stimulus characteristics can even bias the sensory system for illusory percepts. The present ...
