Henderson J, Mari T, Hewitt D, Newton-Fenner A, Giesbrecht T, Marshall A, et al.
Brain Behav . 2023 Sep; 13(11):e3264. PMID: 37749852
Introduction: Humans use discriminative touch to perceive texture through dynamic interactions with surfaces, activating low-threshold mechanoreceptors in the skin. It was largely assumed that texture was processed in primary somatosensory...

Henderson J, Mari T, Hewitt D, Newton-Fenner A, Hopkinson A, Giesbrecht T, et al.
Eur J Neurosci . 2023 Jul; 58(6):3412-3431. PMID: 37518981
Perceptual judgements about our physical environment are informed by somatosensory information. In real-world exploration, this often involves dynamic hand movements to contact surfaces, termed active touch. The current study investigated...

Newton-Fenner A, Hewitt D, Henderson J, Roberts H, Mari T, Gu Y, et al.
PLoS One . 2023 Jul; 18(7):e0286969. PMID: 37428744
Forming and comparing subjective values (SVs) of choice options is a critical stage of decision-making. Previous studies have highlighted a complex network of brain regions involved in this process by...

Henderson J, Mari T, Hopkinson A, Hewitt D, Newton-Fenner A, Giesbrecht T, et al.
Front Neurosci . 2023 Jun; 17:1197113. PMID: 37332863
Introduction: Texture changes occur frequently during real-world haptic explorations, but the neural processes that encode perceptual texture change remain relatively unknown. The present study examines cortical oscillatory changes during transitions...

Newton-Fenner A, Tyson-Carr J, Roberts H, Henderson J, Hewitt D, Byrne A, et al.
Psychophysiology . 2022 Jun; 59(12):e14125. PMID: 35711134
Online retailers often sell products using a socially competitive second-price sealed-bid auction known as a Vickrey auction (VA), an incentivized demand-revealing mechanism used to elicit players' subjective values. The VA...

Hewitt D, Newton-Fenner A, Henderson J, Fallon N, Brown C, Stancak A
J Neurophysiol . 2022 May; 127(6):1629-1641. PMID: 35611988
External low-frequency peripheral nerve stimulation (LFS) has been proposed as a novel method for neuropathic pain relief. Previous studies have reported that LFS elicits long-term depression-like effects on human pain...

Henderson J, Mari T, Hopkinson A, Byrne A, Hewitt D, Newton-Fenner A, et al.
Behav Brain Res . 2022 May; 429:113908. PMID: 35500720
Previous studies have shown attenuation of cortical oscillations over bilateral sensorimotor cortex areas during passive perception of smooth textures applied to the skin. However, humans typically explore surfaces using dynamic...

Byrne A, Hewitt D, Henderson J, Newton-Fenner A, Roberts H, Tyson-Carr J, et al.
Psychophysiology . 2021 Jul; 59(5):e13897. PMID: 34251684
Losses usually have greater subjective value (SV) than gains of equal nominal value but often cause a relative deterioration in effortful performance. Since losses and gains induce differing approach/avoidance behavioral...

Hewitt D, Byrne A, Henderson J, Newton-Fenner A, Tyson-Carr J, Fallon N, et al.
Clin Neurophysiol . 2021 May; 132(7):1481-1495. PMID: 34023628
Objective: Transcutaneous low-frequency stimulation (LFS) elicits long-term depression-like effects on human pain perception. However, the neural mechanisms underlying LFS are poorly understood. We investigated cortical activation changes occurring during LFS...

Front Psychol . 2021 Apr; 12:643542. PMID: 33815229
Screen-based and mobile technology has grown at an unprecedented rate. However, little is understood about whether increased screen-use affects executive functioning (EF), the range of mental processes that aid goal...
