Levodopa: faster and better word learning in normal humans.

• Stefan Knecht, Caterina Breitenstein, +5 authors E. Bernd Ringelstein
• Annals of neurology
• 2004

Dopamine is a potent modulator of learning and has been implicated in the encoding of stimulus salience. Repetition, however, as required for the acquisition and reacquisition of sensorimotor or… (More)

D-Amphetamine Boosts Language Learning Independent of its Cardiovascular and Motor Arousing Effects

• Caterina Breitenstein, Stefanie Wailke, +4 authors Stefan Knecht
• Neuropsychopharmacology
• 2004

D-Amphetamine (AMPH) was effective in a number of studies on motor and language recovery after stroke, but given safety concerns, its general use after stroke is still debated. Most stroke patients… (More)

Effect of controlled-release levodopa on the microstructure of sleep in Parkinson's disease.

• Stefanie Wailke, J Herzog, Klaus Witt, Guether Deuschl, Juliane Volkmann
• European journal of neurology
• 2011

BACKGROUND Dopamine is an important neurotransmitter in the regulation of the sleep-wake cycle, and parkinsonian patients suffer from prominent sleep abnormalities. Hence, the question arises whether… (More)

Stimulation of subthalamic fibre tracts reduces dyskinesias in STN-DBS.

• J Herzog, M. Pinsker, +4 authors Juliane Volkmann
• Movement disorders : official journal of the…
• 2007

Rarely, the postoperative management of patients with subthalamic deep brain stimulation (STN-DBS) is complicated by pharmacologically intractable dyskinesias. Here we report that in three of these… (More)

The Subthalamic Nucleus Influences Visuospatial Attention in Humans

• Barbara Schmalbach, Veronika Günther, +4 authors Karsten Witt
• J. Cognitive Neuroscience
• 2014

Spatial attention is a lateralized feature of the human brain. Whereas the role of cortical areas of the nondominant hemisphere on spatial attention has been investigated in detail, the impact of the… (More)

A shift of paradigm: from noradrenergic to dopaminergic modulation of learning?

• Caterina Breitenstein, Agnes Flöel, Catharina Korsukewitz, Stefanie Wailke, Stefan Bushuven, Stefan Knecht
• Journal of the neurological sciences
• 2006

d-Amphetamine coupled with behavioral training has been effective for improving functional recovery after stroke. d-amphetamine acts on multiple brain transmitter systems, but the recovery enhancing… (More)
