Introduction
My current research focuses on the understanding of cognitive control benefits in meditation and its effects on neurophysiological parameters during motor sequence acquisition. Specifically, I further the understanding of EEG changes that occur during and from meditation, and the ERPs elicited for motor patterning and sequence efficiency. My research interest is interdisciplinary and bridge areas such as motor control, cognitive neuroscience and the psychology of consciousness. My long-term vision is to understand how to tap into the near limitless cognitive potential of the mind, and in turn, use this knowledge to enhance life through the movement capacity of humanity.

Mood disorders are prevalent in people after stroke, and a disorder's onset can exacerbate stroke-related disabilities. While evidence supports the mental-health benefits of participation in exercise and yoga, it is unknown whether such benefits extend to a population with poststroke hemiparesis. The study investigated whether supplementing exercis...

Cognitive control processes influence how motor sequence information is utilised and represented. Since cognitive control processes are shared amongst goal-oriented tasks, motor sequence learning and performance might be influenced by preceding cognitive tasks such as focused-attention meditation (FAM). Prior to a serial reaction time task (SRTT),...
Article
Motor sequence learning is considered the result of the outflow of information following cognitive control processes that are shared by other goal-directed behaviours. Emerging evidence suggests that focused-attention meditation (FAM) establishes states of enhanced cognitive control, that then exert top-down control biases in subsequent unrelated t...
Preprint
Recent theoretical models outline that motor sequence learning involves cognitive control processes that affects stimulus- or plan-based control, although clear contributions from the have not been delineated. Previously, we found that single-session focused attention meditation (FAM) enhanced stimulus-based control through increased top-down activ...

Single-session meditation augmentation of sport-specific skill performance was tested with elite junior tennis athletes. Athletes completed one of two styles of mindfulness meditation (focused-attention or open-monitoring) or a control listening condition prior to performing an implicitly sequenced tennis serve return task involving the goal of hit...

Arthrogryposis multiplex congenita (AMC) has recently drawn substantial attention from researchers and clinicians. New effective surgical and physiotherapeutic methods have been developed to improve the quality of life of patients with AMC. While it is clear that all these interventions should strongly rely on the plastic reorganization of the cent...

There is increased interest in electrophysiological markers of motor sequence learning so as to develop individualized programs. Specifically, β band (15-30Hz) event-related synchronization (ERS) is an important time-frequency predictor for movement-related performances. ERS activation levels likely reflect changes in coherent activity over M1, lin...
Article
Previous work found that single-session focused attention meditation (FAM) enhanced motor sequence learning through increased cognitive control as a mechanistic action, although electrophysiological correlates of sequence learning performance following FAM were not investigated. We measured the persistent frontal N2 event-related potential (ERP) th...

Background Patients with amyoplasia have severe congenital joints contractures with muscle hypoplasia or aplasia. When upper limb muscles like the biceps brachii are absent, soft tissue transplantation from different donor sites help to restore active elbow flexion and improve self-service. The current clinical study focuses on a case where success...

Introduction: At birth, patients with arthrogryposis are characterised by severe muscular weakness, hypotonia, and congenital malformation of the musculoskeletal system which affects their long-term quality of life. When proximal upper limb muscles such as the biceps brachii are absent and implicated, soft tissue surgery is usually performed to tra...

Статья посвящена сравнительному анализу полноты понимания юмора здоровыми людьми (N = 39) и пациентами, страдающими психическими заболеваниями (N = 31): шизофренией и шизотипическими расстройствами (N = 19) и аффективными расстройствами (N = 12). Испытуемым предъявлялся набор из семи вербальных шуток, по которым индивидуально проводилось глубинное...

Chan et al. (2017) demonstrated that top-down control states established in FAM persist to influence subsequent sequence learning through increased stimulus-based planning. To test if top-down control influences on attention allocation and contribute to sequence learning effects of FAM, we compared against a computerised attention task (CAT). We in...

Aims: Understanding the conditions which can optimise motor sequence learning is an important challenge in our field. Recent theoretical models outline that motor learning can be influenced by cognitive control to derive different learning strategies. Growing evidence suggests that mental tasks such as focused attention meditation (FAM) can influen...

Fixation, the difficulty in adapting cognitive processes to meet task changes, has received little attention in sequence learning literature. This is surprising given the degree to which humans must continuously adapt to changing sequential structures. In this experiment, we investigated whether learning a sequence was impeded by preceding practice...

Through their influences on cognitive control processes, hedonic states are able to modulate motor sequence learning and representation. For example, positive hedonic states are thought to promote flexible attention control policies that benefit sequence learning. As meditation induces positive hedonic states, the present experiment tested if medit...

Cognitive control processes that regulate attention, perception and memory systems influence whether motor sequence learning and representation is primarily stimulus or response oriented. Since cognitive control processes are shared amongst goal-directed tasks, adoption of stimulus or response based sequence learning might be influenced by precedin...

Cardiovascular responses (CV) such as heart rate (HR) and blood pressure (BP) are accepted as indicators of physiological demand and psychological stress. However, less is known about how HR and BP respond to cognitive demands independently from the influences of physiological demand and psychological stress. To this end, the present systematic rev...

Due to large variances in response to traditional rehabilitation for mental and physical health symptoms of motor impaired neurological patients, other approaches using complementary and alternative medicine are being explored. Yoga has been increasingly popular for use in the clinical setting for this population. This review illustrates the benefi...

Project
Individualised Cognitive and Motor learning for the Elderly (ICOME) project's innovation is to provide a management solution to the ageing demographics across Europe and the world by creating an evidence-based approach with high efficacy. This is realised with a three-stage approach to investigate and provide a viable solution. In the first stage, historical and current theoretical issues with the quantification of motor learning development in elder adults In the second stage, an integrated neurocognitive model of motor learning representation for the elderly, using supervised machine learning with electroencephalography (EEG) and behavioural data will be created to predict cognitive and motor states. Lastly, individualised intervention with two different forms of meditation is piloted to obtain greater learning outcomes in a shorter timeframe for the elderly. It is expected that elder adults with individualised training will gain benefits such as improved balance control for falls prevention.
Project
Our goal is to disentangle the differences in cortical representations of different movements in children with arthrogryposis using MEG and EEG. We will utilize several neurobiologically relevant markers of motor control and tracking changes overtime. A key objective is to provide additional clinically relevant information to surgeons to enhance their surgical decisions on transplantation. A secondary objective is to also understand why transplantation does not work in some cases and improve functional outcomes.
