Der Effekt der Pulsweite auf die kortikale Erregbarkeit hervorgerufen durch 5-Hz-cTMS
(2022-07-22)Repetitive Transcranial Magnetic Stimulation (rTMS) is known as an important diagnostic and therapeutic clinical tool, for example in treatment of depression. Here, we wanted to optimize stimulation parameters in order to ... -
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 ... -
Neurofunktionelle Alterseffekte in Regionen des mesolimbischen dopaminergen Belohnungsystems unter Verwendung des Desire-Reason-Dilemma-Paradigmas
(2020-10-30)Rewards establish goal-directed behaviors and motivate humans to exert great efforts in a variety of tasks. Dysfunctions in learning and unlearning reward behaviors are linked to a variety of psychiatric diseases. A lot ... -
Decis State - Dysfunktionen neuronaler Mechanismen der Impulskontrolle bei Suchterkrankung –eine funktionell-kernspintomographische Untersuchung von Patienten mit langjähriger Alkoholabhängigkeit
(2020-05-26)The mesolimbic dopamine system plays a central role in the development of addiction. Some of its areas enable quick (impulsive) desires for preferred or conditioned stimuli. On the other hand, pre-frontal areas, which ...

Veränderung der kognitiven Funktionen durch körperliches Training bei Schizophrenie - Eine kontrollierte Studie
(2018-04-12)Aerobic exercise has been shown to improve symptoms in multi episode schizophrenia, including cognitive impairments, but results are inconsistent. Therefore, we evaluated the effects of an enriched environment paradigm ... -
Neuroplastische Effekte transkranieller Nahinfrarotstimulation unterschiedlicher Stimulationsdauer auf die kortikale Exzitabilität
(2018-03-13)Transcranial Near-infrared-Stimulation as a kind of non-invasive Photobiostimulation of the cortex is able to modulate neurobiological functions without causing thermal damage. The aim of this experiment was to study the ... -
Elektrophysiologische Korrelate des Lern- und Wiedererkennungsprozesses in gesunden Probanden
(2018-01-04)Electrophysiological correlates of the knowing process in healthy subjects. The aim was to find bioelectrical correlates in subjects by using EEG and associative learning tasks. In times of the reproducibility crisis it ... -
Die Beeinflussung des instrumentellen Lernens durch Placebo- und Noceboeffekte
(2017-08-09)Placebo / nocebo effects and the underlying mechanisms are currently the subject of intensive research. However, up to the present time, not all backgrounds could be fully illuminated. Numerous studies have been concerned ... -
Beeinflussung der deklarativen Gedächtnisleistung mittels bilateraler transkranieller Gleichstromstimulation (tDCS) über dem parietalen sowie temporalen Kortex
(2016-08-15)Transcranial direct current stimulation (tDCS) is proved so far to be a successful method for investigating complex cognitive functions. There is evidence from imaging studies that parietal and temporal cortices act together ... -
Neuronale Korrelate von Placeboeffekt, Furchtextinktion und willentlicher Emotionsregulation
(2014-08-04)BACKGROUND: It is important to control negative affect and perceived fear in normal life. Problems in emotion regulation lead to diseases like anxiety disorder. Different experimental domains like fear extinction, placebo ... -
Analyse neuropsychologischer Ausfallprofile bei zerebraler Mikroangiopathie
(2013-09-27)Introduction As the population gets older dementia as a disease of the elderly has to be faced more often. After Alzheimer's dementia (AD) cerebral small vessel disease (CSVD) is the most frequent cause of cognitive ... -
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 ... -
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 ... -
Die multimodale Untersuchung kognitiver Prozesse der Mentalen Rotation
(2012-01-10)The mental rotation task according to Shepard RN and Metzler J (1971) is a well established research paradigm to examine cognitive processes of spatial thinking. In this dissertation the ...
