Development of a Piezoelectric Actuated Tactile Stimulation Device for Population Receptive Field Mapping in Human Somatosensory Cortex With fMRI

Abstract: Background Multichannel tactile stimulation devices is need to investigate human finger population receptive field (pRF) characteristics in the primary somatosensory cortex during functional magnetic resonance imaging (fMRI). Purpose To accurately characterize right‐hand somatosensory representation based on the Bayesian pRF model. Study Type Prospective. Population A water phantom and six healthy participants (four males, mean 23.8 years old). Field Strength/Sequence T1‐weighted magnetization‐prepared rapid g… Show more

“…We reasoned that highly trained and experienced participants with a large number of trials would provide us with more reliable within-participant estimates of true effect sizes. Similar small-N approaches have been used earlier in fMRI (O'Connor et al, 2002;Wunderlich et al, 2005;Konen and Kastner, 2008;Meier et al, 2008;Konen et al, 2013;Spitschan et al, 2017;Wu et al, 2022;Fracasso et al 2022). Please see Smith and Little (2018), Baker et al, (2021), andInce et al, (2022) for recent discussions of and perspectives on small-N approaches.…”

“…Vibrotactile stimulation stands out as another widely used method to explore tactile deficits in fMRI studies. There are many pneumatic [10][11][12][13] and piezoelectric [14][15][16][17] tactile stimulation devices that can apply vibrotactile stimuli. There are three concerns in using vibrotactile as a stimulation method.…”

“…Their results also suggested larger pRFs in BA1 and BA2 compared to BA3a and BA3b. Another recent fMRI study (Wu et al 2022 ) developed a piezoelectric actuated tactile stimulation device for pRF mapping at 3T to stimulate a 5 × 2 grid on the digits (D1–D2–D3–D4–D5) at two within-digit locations (distal phalanx, proximal phalanx). An associated editorial of this work (Gilbert 2022 ) highlighted the need for more sophisticated stimulation devices for pRF mapping.…”
