Soto V, Tyson-Carr J, Kokmotou K, Roberts H, Byrne A, Hewitt D, et al.
Front Neurosci . 2024 Dec; 18:1492427. PMID: 39669129
Brain imaging performed in natural settings is known as mobile brain and body imaging (MoBI). One of the features which distinguishes MoBI and laboratory-based experiments is the body posture. Previous...

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...

Mari T, Henderson J, Ali S, Hewitt D, Brown C, Stancak A, et al.
BMC Neurosci . 2023 Sep; 24(1):50. PMID: 37715119
Previous studies have demonstrated the potential of machine learning (ML) in classifying physical pain from non-pain states using electroencephalographic (EEG) data. However, the application of ML to EEG data to...

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...

Mari T, Asgard O, Henderson J, Hewitt D, Brown C, Stancak A, et al.
Sci Rep . 2023 Jan; 13(1):242. PMID: 36604453
Discrimination of pain intensity using machine learning (ML) and electroencephalography (EEG) has significant potential for clinical applications, especially in scenarios where self-report is unsuitable. However, existing research is limited due...

Hewitt D, Byrne A, Henderson J, Wilford K, Chawla R, Sharma M, et al.
Neuromodulation . 2022 Dec; 26(5):975-987. PMID: 36464560
Objectives: Tonic spinal cord stimulation (SCS) is accompanied by paresthesia in affected body regions. Comparatively, the absence of paresthesia with burst SCS suggests different involvement of the dorsal column system...

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...
