Article
Lay abstract: More research has been conducted on how autistic people understand and interpret other people's emotions, than on how autistic people experience their own emotions. The experience of emotion is important however, because it can relate to difficulties like anxiety and depression, which are common in autism. In neurotypical adults and...

Body awareness is constructed by signals originating from within and outside the body. How do these apparently divergent signals converge? We developed a signal detection task to study the neural convergence and divergence of interoceptive and somatosensory signals. Participants focused on either cardiac or tactile events and reported their presenc...
Article
It has been proposed that accurate motor control relies on Bayesian inference that integrates sensory input with prior contextual knowledge (Bays and Wolpert, 2007; Körding and Wolpert, 2004; Wolpert et al., 1995). Recent evidence has suggested that modulations in beta power (∼12-30 Hz) measured over sensorimotor cortices using electroencephalograp...

A number of empirical and theoretical reports link altered interoceptive processing to anxiety. However, the mechanistic understanding of the relationship between the two remains poor. We propose that a heightened sensibility for interoceptive signals, combined with a difficulty in attributing these sensations to emotions, increases an individual’s...
Data
Simplified awareness subscale of the Porges Body Perception Questionnaire. The scale was modified by simplifying the language and removing 6 items, which were deemed collapsible into other items. As an example of language simplification, item 3) ‘An urge to cough to clear my throat’ became ‘A need to cough to clear my throat’. As an example of coll...
Data
Factor analysis of items. Component loadings of items in abbreviated version of Awareness subsection of Porges Body Perception Questionnaire (BPQ [10, 33]), Toronto Alexithymia Scale (TAS-20 [54]) and Trait Form of the State Trait Anxiety Inventory (STAI [53]). The highest factor loading for each item is given below. The rotation converged in 66 it...
Article
A recent theoretical account of motor control proposes that modulation of afferent information plays a role in affecting how readily we can move. Increasing the estimate of uncertainty surrounding the afferent input is a necessary step in being able to move. It has been proposed that an inability to modulate the gain of this sensory information und...

Spatial and temporal expectations act synergistically to facilitate visual perception. In the current study, we sought to investigate the anticipatory oscillatory markers of combined spatial-temporal orienting and to test whether these decline with ageing. We examined anticipatory neural dynamics associated with joint spatial-temporal orienting of...
Article
Interoception describes the processing and awareness of bodily signals arising from visceral organs, essential for the organism's homeostatic needs. Beyond homeostasis, the integration of exteroceptive and interoceptive signals is required for the coherence of bodily self-awareness. Here we suggest that interoception also plays a critical role in s...

Cognitive impairment is common amongst many neurodegenerative movement disorders such as Huntington’s disease (HD) and Parkinson’s disease (PD) across multiple domains. There are many tasks available to assess different aspects of this dysfunction, however, it is imperative that these show high test–retest reliability if they are to be used to trac...
Article

Significance statement: We demonstrate that there are two functionally and mechanistically distinct forms of sensory gating. The literature regarding somatosensory evoked potential (SEP) gating is commonly cited as a potential mechanism underlying perceptual sensory attenuation; however, the formal relationship between physiological and perceptual...

It has been proposed that motor system activity during action observation may be modulated by the kinematics of observed actions. One purpose of this activity during action observation may be to predict the visual consequence of another person's action based on their movement kinematics. Here, we tested the hypothesis that the primary motor cortex...

Oscillatory activity in the beta frequency range from sensorimotor cortices is modulated by movement; however, the functional role of this activity remains unknown. In a recent study, Tan et al. tested a novel hypothesis that beta power reflects estimates of uncertainty in parameters of motor forward models.

Conference Paper
During movement incoming sensory information is filtered via central mechanisms: sensory gating. This gating has been described at two levels. At a neurophysiological level cortical electroencephalogram (EEG) recordings have highlighted a suppression of somatosensory evoked potentials (SEPs), produced in response to electrical stimulation of the me...

Adult rats exposed to methylazoxymethanol acetate (MAM) at embryonic day 17 (E17) display robust pathological alterations in the hippocampus. However, discrepancies exist in the literature regarding the behavioural effects of this pre-natal manipulation. Therefore, a systematic assessment of MAM E17-induced behavioural alterations was conducted usi...
