A cross cultural study of motor development in the Western Cape
Despite conflicting evidence regarding advanced motor behaviour in black African infants, very few comparative studies have been published. Reliable developmental norms for local populations are essential for the early identification of developmental disabilities. In this study the sample consisted …

Sex and LRRK2 Genotype Differences in Inflammation and Dopaminergic Neurodegeneration in a Multi-Hit Model of Parkinson's Disease
… environmental risk factors as they pertain to motor behaviour, nigrostriatal dopaminergic degeneration, and neuroinflammation. Moreover, since the male sex represents a significant risk factor in PD, sexual dimorphisms were addressed. To achieve this, male and female mice bearing the …

Sensibilizzazione alla caffeina e sensibilizzazione all'amfetamina: influenza della suscettibilità individuale agli effetti della caffeina
… of caffeine to induce a sensitized motor response and correlated the individual susceptibility of rats to acute caffeine to the development of sensitization. Moreover, individual susceptibility to caffeine and development of motor behaviour sensitization were correlated to the …

Sensory and Cognitive Influences on Oculomotor and Whole-body Coordination during Standing Turns
… movements during turns. We found that eye and motor behaviour during vision removal was similar to behaviour during full vision, however suppressing eye movements delayed gait initiation and decreased stepping frequency throughout the turn. Next we examined the influence of neck muscle …

Investigating the Sophistication of Long-Latency Stretch Responses During Postural Control of the Upper Limb
A recent theory of motor control, based on optimal feedback control, posits that voluntary motor behaviour involves the sophisticated manipulation of sensory feedback. Although this theory can explain how people move in the world, it does not specifically describe how this control process is …

Physical Literacy and South East Wales Primary School Children: The Role of Fundamental Movement Skills
… specific focus on the relationships between FMS motor behaviour competency and other aspects of physical literacy. The aims of this thesis were to: (a) examine the factor structure of the Children and Youth Physical Self-Perception Profile (CY-PSPP), based on the validation work of Welk and …

A qualitative and quantitative study of the nature of developmental coordination disorder
… subtypes and/or additional factors would have on motor development. BACKGROUND Developmental Coordination Disorder (DCD) is a chronic, often permanent condition evident from early childhood, characterised by difficulties performing a range of movement tasks that are not explainable by neurological …

Therapeutic potential of targeting group III metabotropic glutamate receptors as a disease modifying strategy in the treatment of Parkinson’s disease
… unilateral 6-OHDA lesion of the SN, confirmed by behavioural assessment and post-mortem analyses.<br/><br/>Secondly, the pharmacological identity of the group III mGlu receptor mediating this protective effect was examined. To investigate mGlu4 receptors, the novel mGlu4 selective PAM VU0155041, …

Effect of Cannabinoids and Stress on Motor Maps and Behaviour
Motor maps exhibit experience dependent changes and are therefore sensitive to the type and amount of neurotransmitters present in the motor cortex and changes in motor map expression often results in impairments of skilled behaviour. Endocannabinoids have been shown to affect spinal locomotion and …

Robotic Assessment to Detect Neurological Impairments Associated with Transient Ischemic Attack
… disease, and stroke. Their ability to measure motor behaviour precisely and reliably makes them ideal candidates to understand how TIA affects behaviour, and differs from other clinical conditions. In this thesis, the Kinarm robotic assessment system is used to characterize neurological …

Chemomechanical coupling and motor cycles of the molecular motor myosin V
… structure relies to a large extent on molecular motors. Molecular motors are proteins that are able to convert chemical energy from the hydrolysis of adenosine triphosphate (ATP) into mechanical work. Being about 10 to 100 nanometers in size, the molecules act on a length scale, for which thermal …

Directed transport without net bias in physics and biology

Ontogenetic and comparative aspects of cerebellar and motor development
During the course of development the motor repertoire of animals and humans alike go through dramatic changes. New motor patterns arise; movements become coordinated, improve in precision and are at the same time continuously calibrated to the changing body dimensions. The cerebellum is critical …

The microbiome-gut-brain axis in preclinical alpha-synuclein models of Parkinson's disease
… nervous systems and is characterised by motor and non-motor symptoms. The primary pathological features of PD are the degeneration of the nigrostriatal pathway in the brain, causing motor dysfunction, and the build-up of α-synuclein protein fibrils throughout several brain regions. Many …

Factors that influence motor performance: Colour, inhibition and conscious processing
… psychological mechanisms that influence motor performance in sport, including colour, inhibition function, and propensity for conscious control of movement. A question was raised about whether individuals with poor inhibition function would be more likely to have a high propensity for …
