Insights
A new electroencephalography (EEG)-based brain mapping system effectively creates topographical maps comparable to functional magnetic resonance imaging (fMRI) in children. This novel system accurately visualizes brain activity in both typically developing children and those with cerebral palsy (CP) during motor tasks.
Area of Science:
- Neuroscience
- Biomedical Engineering
- Pediatric Neurology
Background:
- Functional magnetic resonance imaging (fMRI) is a common tool for mapping brain activity.
- Cerebral palsy (CP) affects motor function and brain development in children.
- Developing accessible and effective neuroimaging techniques for pediatric populations is crucial.
Purpose of the Study:
- To compare brain topographical maps generated by a novel electroencephalography (EEG)-based system with those from fMRI.
- To evaluate the efficacy of the EEG system in normal children and children with CP during a grasping motor task.
Main Methods:
- A novel EEG-based brain mapping system with 30 scalp sites was utilized.
- fMRI was employed using a 3T MR scanner for comparative analysis.
- Cortical activation patterns were observed in one normal child and four children with CP during a grasping motor task.
Main Results:
- EEG and fMRI data showed sensorimotor cortex (SMC) activation in all participants.
- Children with CP exhibited additional activation in the premotor cortex (PMC) and primary somatosensory cortex (PSC) on fMRI.
- EEG data revealed additional activation in the premotor cortex (PMC), superior parietal cortex (SPC), and prefrontal cortex (PFC) in children with CP.
Conclusions:
- The EEG-based topographical maps demonstrated equivalence to fMRI maps during the grasping task.
- The novel EEG brain mapping system is a valuable tool for assessing cortical activation in children, including those with CP.
Purpose:
The purpose of this study was to compare topographical maps using a novel EEG-based brain mapping system with fMRI in normal and children with cerebral palsy (CP) during a grasping motor task.
Method:
A normal child (mean ± SD = 13 ± 0 yrs) and four children with CP (mean ± SD = 10.25 ± 2.86 yrs) were recruited from a local community school and medical center. A novel EEG-based brain mapping system with 30 scalp sites (an extension of the 10-20 system) and a 3T MR scanner were used to observe cortical activation patterns during a grasping motor task.
Design:
Descriptive analysis.
Results:
In the EEG brain mapping data, the sensorimotor cortex (SMC) and inferior parietal cortex (IPC) were activated in all of the children. The children with CP showed additional activation areas in the premotor cortex (PMC), superior parietal cortex (SPC), and prefrontal cortex (PFC). In the fMRI brain mapping data, SMC activation was observed in all of the children, and the children with CP showed additional activation areas in the PMC and primary somatosensory cortex (PSC).
Discussion:
The EEG-based topographical maps were equivalent to the maps obtained from fMRI during the grasping motor task. The results indicate that our novel EEG-based brain mapping system is useful for probing cortical activation patterns in normal children and children with CP.
