Nonlinear Asymmetric Blood Oxygenation Level Dependent Responses in Somatosensory Cortex [PDF]
Hum Brain MappBOLD responses to increments and decrements in intensity of vibrotactile stimulation were asymmetric. Negative BOLD effects (decrements in signal) were smaller in amplitude and slower to peak compared with positive BOLD responses to increases of intensity. BOLD responses were nonlinear for changes in stimulus duration and intensity.

Repeated training with augmentative vibrotactile feedback increases object manipulation performance. [PDF]
PLoS ONE, 2012 Most users of prosthetic hands must rely on visual feedback alone, which requires visual attention and cognitive resources. Providing haptic feedback of variables relevant to manipulation, such as contact force, may thus improve the usability of ...

Speech-derived haptic stimulation enhances speech recognition in a multi-talker background
Scientific Reports, 2023 Speech understanding, while effortless in quiet conditions, is challenging in noisy environments. Previous studies have revealed that a feasible approach to supplement speech-in-noise (SiN) perception consists in presenting speech-derived signals as ...
