Case Report: No effect of electrical transcranial direct current stimulation adjunct treatment for epilepsia partialis continua in POLG disease
Marquardt, Lynn Anne; Eichele, Tom; Bindoff, Laurence; Olberg, Henning Kristian; Veiby, Gyri; Eichele, Heike; Kusztrits, Isabella; Hirnstein, Marco (Journal article; Peer reviewed, 2019)We report a 15-year-old female with POLG-related mitochondrial disease who developed severe multifocal epilepsia partialis continua, unresponsive to standard anti seizure drug treatment and general anesthesia. Based on an ... -
EEG Analysis in Adults with Attention-Deficit-Hyperactivity-Disorder. Resting state and behavioural data analysis
Marquardt, Lynn Anne (Master thesis, 2015-05-31)Introduction: Adults with attention-deficit/hyperactivity disorder (ADHD) are examined by electroencephalography (EEG). EEG is a non-invasive method to measure brain activity indirectly, by measuring voltage changes on the ... -
Event-related-potential (ERP) correlates of performance monitoring in adults with attention-deficit hyperactivity disorder (ADHD)
Marquardt, Lynn Anne; Eichele, Heike; Lundervold, Astri; Haavik, Jan; Eichele, Tom (Peer reviewed; Journal article, 2018-04-11)Introduction: Attention-deficit hyperactivity disorder (ADHD) is one of the most frequent neurodevelopmental disorders in children and tends to persist into adulthood. Evidence from neuropsychological, neuroimaging, and ... -
Mapping psychotic-like experiences: Results from an online survey
Kusztrits, Isabella; Larøi, Frank; Laloyaux, Julien Freddy; Marquardt, Lynn Anne; Sinkeviciute, Igne; Kjelby, Eirik; Johnsen, Erik; Sommer, Iris Else Clara; Hugdahl, Kenneth; Hirnstein, Marco (Journal article; Peer reviewed, 2021)Suggestions have been made that psychotic‐like experiences (PLEs), such as hallucinatory and delusional experiences, exist on a continuum from healthy individuals to patients with a diagnosis of schizophrenia. We used the ... -
A multimodal study of the effects of tDCS on dorsolateral prefrontal and temporo-parietal areas during dichotic listening
Marquardt, Lynn Anne; Kusztrits, Isabella; Craven, Alexander R.; Hugdahl, Kenneth; Specht, Karsten; Hirnstein, Marco (Journal article; Peer reviewed, 2020)The underlying neural mechanisms of transcranial direct current stimulation (tDCS), especially beyond the primary motor cortex, remain unclear. Several studies examined tDCS effects on either functional activity, ... -
Pilot-RCT Finds No Evidence for Modulation of Neuronal Networks of Auditory Hallucinations by Transcranial Direct Current Stimulation
Marquardt, Lynn Anne; Craven, Alexander R.; Hugdahl, Kenneth Jan; Johnsen, Erik; Kroken, Rune Andreas; Kusztrits, Isabella; Specht, Karsten; Thomassen, Anne Synnøve; Weber, Sarah; Hirnstein, Marco (Journal article; Peer reviewed, 2022-10-12)Background: Transcranial direct current stimulation (tDCS) is used as treatment for auditory verbal hallucinations (AVH). The theory behind the treatment is that tDCS increases activity in prefrontal cognitive control ... -
tDCS as treatment in neuro-psychiatric disorders : The underlying neuronal mechanisms of tDCS treatment of auditory verbal hallucinations
Marquardt, Lynn Anne (Doctoral thesis, 2021-02-04)Transcranial direct current stimulation (tDCS) is a form of non-invasive brain stimulation which has gained widespread interest in neurology and psychology, both as a clinical and research tool. While it has been explored ... -
Temporal Signatures of Auditory Verbal Hallucinations: An App-Based Experience Sampling Study
Bless, Josef J; Hjelmervik, Helene; Torsheim, Torbjørn; Gudmundsen, Magne; Larøi, Frank; Holma, Irina; Arola, Anne; Korkeila, Jyrki; Hirnstein, Marco; Marquardt, Lynn Anne; Kusztrits, Isabella; Smelror, Runar; Agartz, Ingrid; Hugdahl, Kenneth (Peer reviewed; Journal article, 2020)The assessment of auditory verbal hallucinations (AVHs) has traditionally been conducted through (semi-)structured interviews, such as the Positive and Negative Syndrome Scales (PANSS; Kay et al., 1987) and the Psychotic ... -
Transcranial direct current stimulation (tDCS) enhances internal source monitoring abilities in healthy participants
Kusztrits, Isabella; Marquardt, Lynn Anne; Hugdahl, Kenneth Jan; Hirnstein, Marco (Journal article; Peer reviewed, 2021-09-16)Source monitoring refers to the ability to identify the origin of a memory, for example, whether you remember saying something or thinking about it, and confusions of these sources have been associated with the experience ...
