Resumo(s)
The development of devices capable of delivering tactile and thermal feedback have the potential to improve brain-machine interfaces for neurorehabilitation protocols. Monetary rewards are known to improve some types of passive tactile processing. The aim of this study was to describe the performance and neural activity of subjects receiving tactile stimuli through a tactile stimulation sleeve in the presence or absence of monetary rewards. Healthy subjects were required to discriminate between different tactile stimulation patterns delivered through a stimulation sleeve while their neural activity was recorded with Electroencephalography (EEG). Behaviorally, no significant differences were observed in the performances of subjects wearing the sleeve. Meanwhile, analysis of neural activity revealed that the introduction of monetary rewards consistently generated significant differences in theta frequency band for occipital electrodes. These results support the notion that monetary rewards can significantly influence tactile information processing.
