Global and local information processing in children with Pervasive Developmental Disorder (PDD): the role of spatial frequency processing M.A. Boeschoten, C. Kemner, J.L. Kenemans, H. van EngelandUnder revision. Abstract: Converging evidence suggests that atypical global-local processing (i.e., a local bias) is an important feature of PDD. The neurocognitive basis of this phenomenon is unclear. This study tested whether a local bias in the Navon task in children with PDD was related to an abnormal processing of spatial frequency content. To this end, performance and event-related potentials (ERPs) in response to low-pass and high-pass filtered hierarchical stimuli were measured in children with PDD and matched controls. In line with earlier findings, spatial frequency processing was abnormal in the children with PDD: they showed less robust spatial frequency-related differences in ERP amplitude at occipital electrodes in comparison to controls. Moreover, spatial frequency was associated with global-local processing. However, the atypical spatial frequency processing appeared not to be associated with abnormal global-local processing in the children with PDD. Instead, both groups of children showed the same effects of spatial frequency content on global-local processing as reflected by reaction time, ERP latency, and ERP amplitude. In conclusion, although atypical spatial frequency processing might be an important characteristic of PDD, the findings of this study do not support it being an explanation for the abnormal global-local processing often seen in subjects with PDD. However, in this study stimulus properties may have obscured the findings on global-local processing. Therefore, more research using different types of filtered global-local stimuli is strongly recommended.  Publication by ANT staff |

Abnormal spatial frequency processing in high functioning children with Pervasive Developmental Disorder (PDD) M.A. Boeschoten, C. Kemner, J.L. Kenemans, H. van EngelandClinical Neurophysiology, Vol 118(9):2076-88, 2007. Abstract: OBJECTIVE: Basic abnormalities in visual information processing could be associated with the local visual bias often found in subjects with PDD. Therefore, the present study investigated the existence of deficits in spatial frequency processing at an early sensory level in children with PDD. METHODS: Visual evoked potentials (VEPs) and VEP dipole sources elicited by high and low spatial frequency gratings were analysed in children with PDD and matched controls. RESULTS: Children with PDD did not show the same robust differences between high and low spatial frequencies in VEP peaks (N80/P1) and VEP brain sources as control children, mainly because of atypical processing of high spatial frequencies. CONCLUSIONS: Decreased specialized processing of high and low spatial frequencies might be a robust characteristic of PDD. Because the processing of local and global aspects in visual information is associated with the processing of high and low spatial frequencies, respectively (e.g., Goffaux et al., 2005; Boeschoten et al., 2005a), the present data suggest that the local visual bias in subjects with PDD might be associated with an abnormality spatial frequency processing. SIGNIFICANCE: The existence of an abnormality in spatial frequency processing in PDD is validated Publication by ANT staff |
Face processing in Pervasive Developmental Disorder (PDD): the roles of expertise and spatial frequency M.A. Boeschoten, C. Kemner, J.L. Kenemans, H. van EngelandJournal of Neural Transmission, Jul 18, 2007. Abstract: Both a reduced face expertise and a basic abnormality in visual information, e.g. spatial frequency, processing have been proposed as possible causes of the abnormal face processing in PDD. This study investigated both the roles of expertise and spatial frequency for face processing in PDD. Event-related potentials (ERPs) and dipole sources were measured in response to (upright/inverted) high- and low-pass filtered faces, houses, and stimuli for which children with PDD were experts. ERP analyses for specific posterior electrodes showed no differences between children with PDD and matched controls, but source analyses did. These showed that controls activated specialized brain sources for the processing of faces, which was dependent on low spatial frequency content. However, PDD children did not. Importantly, present results argue against the idea that this is due to a reduced face expertise on the part of the PDD children, but instead support an abnormality in spatial frequency processing.

Influence of Anisotropic Conductivity on EEG Source Reconstruction: Investigations in a Rabbit Model D. Guellmar, J. Haueisen, M. Eiselt, F. Giessler, L. Flemming, A. Anwander, T.R. Knoesche, C.H. Wolters, M. Duempelmann, D.S. Tuch, J.R. ReichenbachIEEE Trans. Biomed. Eng., Vol. 53, No. 9, 1841-1850, 2006. Abstract: The aim of our work was to quantify the influence of white matter anisotropic conductivity information on electroencephalography (EEG) source reconstruction. We performed this quantification in a rabbit head using both simulations and source localization based on invasive measurements. In vivo anisotropic (tensorial) conductivity information was obtained from magnetic resonance diffusion tensor imaging and included into a high-resolution finite-element model. When neglecting anisotropy in the simulations, we found a shift in source location of up to 1.3 mm with a mean value of 0.3 mm. The averaged orientational deviation was 10 degree and the mean magnitude error of the dipole was 29%. Source localization of the first cortical components after median and tibial nerve stimulation resulted in anatomically verified dipole positions with no significant anisotropy effect. Our results indicate that the expected average source localization error due to anisotropic white matter conductivity is within the principal accuracy limits of current inverse procedures. However, larger localization errors might occur in certain cases. In contrast, dipole orientation and dipole strength are influenced significantly by the anisotropy. We conclude that the inclusion of tissue anisotropy information improves source estimation procedures. Publication by ANT staff |

Time-varying differences in evoked potentials elicited by high versus low spatial frequencies: a topographical and source analysis M.A. Boeschoten, C. Kemner, J.L. Kenemans, H. van EngelandClinical Neurophysiology, Vol 116(8):1956-1966, 2005. Abstract: OBJECTIVE: To investigate time-varying differences in visual-evoked potentials (VEPs) and dipoles elicited by high versus low spatial frequencies. The main question was whether different spatial frequencies are processed in distinct cortical areas, especially after 100 ms. An additional question was whether and how a hemispheric balance in spatial frequency processing develops over time. METHODS: Stimuli were square-wave gratings, with spatial frequencies of 0.75, 1.5, and 6 c/d. VEPs and dipole models were analyzed at various latencies. RESULTS: For the time-window of 80-100 ms, spatial frequency-related differences in VEPs and dipoles in posterior regions as reported previously were replicated: lower spatial frequencies were associated with more positivity in the VEP and with more anterior and radial sources than high frequencies. However, after 100 ms differences in amplitude, but not in topography and dipoles, were found between the different spatial frequencies. Between 180-200 ms a right hemisphere dominance was found for all frequencies. CONCLUSIONS: After 100 ms, VEPs in response to different spatial frequencies seem to be generated in the same cortical areas. Also, no evidence for frequency-related hemispheric lateralization was found. SIGNIFICANCE: Insight is provided into the functional-anatomical basis of longer-latency frequency-related differences in processing. Publication by ANT staff |
The relationship between local and global processing and the processing of high and low spatial frequencies studied by event-related potentials and source modeling M.A. Boeschoten, C. Kemner, J.L. Kenemans, H. van EngelandCognitive Brain Research, Vol. 24(2): 228-236, 2005. Abstract: The processing of global and local elements and of low- and high-spatial frequencies are thought to be interrelated. Evidence for this stems from findings showing that brain localizations for global/local elements and for low/high spatial frequencies seem to overlap. The present study aimed to provide direct evidence that topographical differences between the processing of global and local visual elements can directly be explained by their spatial frequency content, and to study at which point in time this relation is present. This was done by studying the event-related potentials (ERPs) and source models elicited by unfiltered, low- or high-pass filtered hierarchical stimuli. Results showed that performance for global and local targets was affected by removing low and high spatial frequencies, respectively. ERP data indicated that at 250 ms, there was an interaction between the processing of global/local targets and of spatial frequencies because at this time-point removal of low spatial frequencies decreased activity associated with the processing of global targets. When localizing this effect, we found evidence implying that spatial frequency content indeed affected the brain region in which local/global targets were processed. Results implicated that the processing of global information depended on its low spatial frequency content, which was processed more laterally. Instead, processing of local information seemed to depend on its high spatial frequency content, which was processed more medially. Thereby, present results extend former results showing that global and local processing is dependent on spatial frequency and mapped retinotopically in the visual cortex. Publication by ANT staff |
