Pain Observation, Empathy, and the Sensorimotor System: Behavioural and Neurophysiological Explorations
… another in pain activates both affective and sensorimotor cortical activity that is also present during the first-hand experience of pain. Some researchers have taken this “mirroring” response as indicative of empathic processing. However, very little work has explored the downstream …

The Long-Term Teratogenic Effect of Prenatal Alcohol Exposure on the Somatosensory and Motor Cortex of Rats
… craniofacial dysmorphologies and central nervous system disruptions) diagnosed as fetal alcohol syndrome (FAS) in children and adults. Since low to moderate levels of prenatal alcohol exposure are less likely to produce FAS symptoms in children, the term “PAE” in this dissertation typically refers …

MORE THAN FINGER COUNTING: SHARED RESOURCES BETWEEN FINGER TAPPING AND ARITHMETIC
… thinking relates to our body and the sensorimotor system. Abundant behavioral, neuroimaging, and neuropsychological evidence have accumulated over the last two decades showing a relationship between number processing and sensorimotor processes. In addition, considerable evidence has …

Somatosensory Involvement in the Conceptual Representation of Objects
The involvement of the sensorimotor system in visual object processing is at the forefront of cognitive neuroscience research. Since the discovery of the mirror neuron system, a plethora of research has been dedicated to understanding how action influences cognition. Of particular interest to the …

Reward and prediction errors in Bayesian sensorimotor control
… (phasic dopamine). Recent studies on Bayesian sensorimotor control have implicated midbrain dopamine concentration in the integration of prior knowledge and current sensory information. The present behavioral study addressed the contributions of tonic and phasic dopamine in a Bayesian …

Visuomotor Learning and Proprioception Across Development
… visuomotor adaptation paradigms where the motor system is challenged to compensate for changes in vision, such as learning to reach to targets on a screen with a misaligned hand-cursor, which our brains do through trial-and-error. A motor command is sent to the arm and a prediction of the outcome …

Action Intentions and the Puzzle of Non-Willed Behaviour
… states, rather than the current state of the sensorimotor system. Finally, Experiment 7 provided evidence that the tendency to produce action slips is positively associated with individual differences in ideomotor suggestibility. These findings reveal how people are able to interact so …

Experience Dependent Sensorimotor Functioning in Adults with Severe Autism Spectrum Disorder
… research was to provide new insights into sensorimotor development and functioning in autistic adults. First, classification measures (Chapter Two) were used to verify the diagnosis of autism, and automatic imitation (Chapter Three) was used to verify an intact perception-action link. In …

fMRI for mapping the plastic somatotopy of primary somatosensory cortex - Development and clinical applications
… these groups, evidence of plastic changes in the sensorimotor system were found. This suggests that plastic processes could be an underlying mechanism for the symptoms experienced in patients following nerve injury and neuropathy. Finally, alternative methods for mapping functional networks of the …

Sensorimotor learning under switching dynamics
… computational modelling to investigate how the sensorimotor system uses contextual information to create, update and recall motor memories. We first examine the role of muscle co-contraction in the learning of novel movement dynamics. We show that muscle co-contraction, as measured by surface …

Towards Understanding the Effects of Exoskeletons on Sensory Integration and Step Regulation
… a human and all the complexities of their sensorimotor system in the control loop. The general idea behind assistance at the lower limbs involves augmenting the joint forces while not interfering with the user's intent. However, the human body is highly redundant, locomotive tasks can be …

Real-time brain-machine interface architectures : neural decoding from plan to movement
… the past decade. However, performance of these systems needs to be significantly improved before they become clinically viable. Moreover, while developing high-performance BMIs with the goal of matching the original motor function is indeed valuable, a compelling goal is that of designing BMIs …

Neural Mechanisms of Motor Imagery and Training-Induced Plasticity: Hypnotizability Relevance to Microgravity Adaptation
… alteration regarding sensory information, sensorimotor integration, and interoceptive and vestibular feedback disruption. Such alterations impair postural control, spatial orientation, and fine motor skills. Motor imagery (MI), defined as the mental simulation of movement without overt …
