Dysfunction of attention switching networks in amyotrophic lateral sclerosis
2019
Objective To localise and characterise changes in cognitive networks in Amyotrophic Lateral Sclerosis (ALS) using source analysis of mismatch negativity (MMN) waveforms. Rationale The MMN waveform has an increased average delay in ALS. MMN has been attributed to change detection and involuntary attention switching. This therefore indicates pathological impairment of the neural network components which generate these functions. Source localisation can mitigate the poor spatial resolution of sensor-level EEG analysis by associating the sensor-level signals to the contributing brain sources. The functional activity in each generating source can therefore be individually measured and investigat…
P 61. Is high frequency rTMS a new tool in remediating dyslexia?
2013
Introduction Evidence from functional neuroimaging has reported hypoactivation of the left parieto-temporal regions in children and adults with dyslexia when they engage in reading-related tasks (Shaywitz et al., 2002; Richlan et al., 2011). Studies on the remediation of dyslexia have consistently found that remedial treatment improves reading ability and increases activation in critical brain areas (Temple et al., 2003; Hoeft et al., 2011). Objectives We wanted to determine whether high frequency repetitive trancranial magnetic stimulation (hf-rTMS) over areas that are underactive in dyslexics during reading, such as the left superior temporal gyrus (STG) and the left inferior parietal lob…
How to improve reading skills in dyslexics: the effect of high frequency rTMS.
2013
The latest progress in understanding remediation of dyslexia underlines how some changes in brain are a necessary mechanism of improvement. We wanted to determine whether high frequency repetitive transcranial magnetic stimulation (hf-rTMS) over areas that are underactive during reading in dyslexics, would improve reading of dyslexic adults. We applied 5Hz-TMS over both left and right inferior parietal lobule (IPL) and superior temporal gyrus (STG) prior to word, non-word and text reading aloud. Results show that hf-rTMS stimulation over the left IPL improves non-word reading accuracy and hf-rTMS stimulation over the left STG increases word reading speed and text reading accuracy. Moreover …
