- Relationship between saccadic eye movements and cortical activity as measured by fMRI: quantitative and qualitative aspectsH Kimmig
Neurologische Universitatsklinik, Breisacher Str 64, 79106 Freiburg, Germany
Exp Brain Res 141:184-94. 2001..We hold that a quantitative analysis of saccade parameters (especially saccade frequency and latency) is important for the interpretation of the BOLD changes observed with visual stimuli in fMRI...
- Role of anterior and occipital white matter lesions for smooth eye tracking in myotonic dystrophyH Kimmig
Abteilung Neurologie, Universitatsklinik Freiburg, Germany
J Neurol Neurosurg Psychiatry 72:808-11. 2002..Imaging and histopathological studies have shown considerable areas of white matter lesions (WMLs) with periventricular emphasis...
- What is pathological with gaze shift fragmentation in Parkinson's disease?Hubert Kimmig
Neurologische Universitatsklinik, Breisacher Strasse 64, 79106 Freiburg, Germany
J Neurol 249:683-92. 2002..Thus, only the abnormally high incidence of fragmentation, and of the associated amplitude reduction of the primary saccades, rather than the phenomenon per se, can be used as a diagnostic criterion in early stages of PD...
- Changes in cortical activation during mirror reading before and after training: an fMRI study of procedural learningJ Kassubek
Department of Neurology, University of Freiburg, Breisacher Strasse 64, 79106, Freiburg, Germany
Brain Res Cogn Brain Res 10:207-17. 2001..The present findings confirm the hypothesis of practice-related decrease of activation in task-related cortical areas during nonmotor procedural learning...
- The initiation of smooth pursuit eye movements and saccades in normal subjects and in "express-saccade makers"H Kimmig
Neurologische Universitatsklinik Freiburg, Breisacher Str 64, 79106 Freiburg, Germany
Exp Brain Res 144:373-84. 2002..Normal pursuit but abnormal saccade RT of ES makers can be explained by recent theories of superior colliculus (SC) function in terms of retinal error handling...
- Gaze pursuit, 'attention pursuit' and their effects on cortical activationsS Ohlendorf
Neurologische Universitatsklinik, D 79106 Freiburg, Germany
Eur J Neurosci 26:2096-108. 2007..Riggio, L., Dascola, I. & Umilta, C. (1987) Neuropsychologia, 25, 31-40]...
- MR-eyetracker: a new method for eye movement recording in functional magnetic resonance imagingH Kimmig
Department of Neurology, University Hospital Freiburg, Germany
Exp Brain Res 126:443-9. 1999..Since the signal is purely optical, there is no interaction between the eye movement signals and the echoplanar images. This reasonably priced eye tracker can be used to control eye position and monitor eye movements during fMRI...
- Coherent motion pops out during smooth pursuitMark W Greenlee
Institute of Cognitive Science, University of Oldenburg, , 26111 Oldenburg, Germany
Neuroreport 13:1313-6. 2002..We tentatively propose that an efference copy of the eye movement signal can enhance the ability of the visual system to detect correlations between sparsely placed targets among noisy distractors...
- Event-related fMRI responses in the human frontal eye fields in a randomized pro- and antisaccade taskFrans W Cornelissen
Laboratory for Experimental Ophthalmology and Department of Biological Psychiatry, School for Behavioral and Cognitive Neurosciences, University of Groningen, P O Box 30 001, 9700 RB Groningen, The Netherlands
Exp Brain Res 145:270-4. 2002..Frontal eye field BOLD activity may further represent general arousal, preparatory set, short-term memory, or salience-map related activity...
- Long-term eye movement recordings with a scleral search coil-eyelid protection device allows new applicationsAndreas Sprenger
Department of Neurology, University Lübeck, Ratzeburger Allee 160, D 23538 Lubeck, Germany
J Neurosci Methods 170:305-9. 2008..This advanced method allows new applications like eye movement recordings during sleep (rapid eye movements) or perceptional or motor learning tasks, e.g. saccade adaptation paradigms...
