Aniseikonia: A Potential Barrier To Neural Plasticity
… represents a potential barrier to neuroplasticity, which may limit visual outcomes in children with anisometropic amblyopia. Full refractive correction is the initial treatment for amblyopia, which corrects image focus, but image size differences are often neglected. We aimed to identify …

Neural Sympathy: Towards Interfaces Compatible with Neural Plasticity
… interfaces (BMIs) enable a direct mapping from neural activity to interactions with the world. They have clinically validated applications for patients with severe loss of motor function, but also offer valuable scientific tools for probing the neural mechanisms of how actions are learned, …

An Examination Of The Persistence Of Kindling, A Model For Neural Plasticity
The primary purpose of the experiments discussed here was to discover whether kindling is a permanent and stable state or a slowly eroding persistent state. In addition, questions concerning the relationship between retention and seizure generalization, site of stimulation, and stimulus …

Repeated amphetamine exposure and the enduring consequences on behavioral and neural plasticity
Amphetamines (AMPH) are relatively unique amongst the category of psychoactive drugs, as they are both prescribed for therapeutic purposes at an alarmingly increasing rate and abused illicitly on account of their potential pleasurable effects (World Drug Report, 2012). In adult subjects, chronic …

Examining Hippocampal Reelin Expression and Neural Plasticity in an Animal Model of Depression
… for regulating neuronal maturation and synaptic plasticity in the adult brain. Interestingly, recent post- mortem analyses indicate that reelin expression is decreased in depressed patients. Similarly, preclinical research has shown that repeated glucocorticoid administration significantly …

Neural Plasticity and the Development of Intersensory Functioning in Bobwhite Quail (Colinus virginianus)
… a link between early experience and neuronal plasticity, it has been established that unusual visual experience can produce measurable changes in post-synaptic structures, particularly dendritic morphology, in brain areas responsible for vision. In avian species, the brain area responsible for …

Neural Plasticity in the Amygdala Across the Development of an Incentive Cocaine Seeking Habit
… and seeking, I aimed to elucidate the cellular plasticity mechanisms in the amygdala that underlie this functional shift. The General Introduction in Chapter 1 gives an overview of the literature informing the approach I took, the methodology of which is presented in Chapter 2, The General …

Characterisation of new regulators and neural plasticity of the O2-sensing circuit in Caenorhabditis elegans
… of how sensory deprivation induces homeostatic plasticity, we propose that, in sensory defective mutants, similar mechanisms might sensitise ADL to incoming activity from the O2-circuit and promote O2-escape behaviour. Moreover, we also investigate the extent to which prolonged oxygen exposure …

ECoG correlates of visuomotor transformation, neural plasticity, and application to a force-based brain computer interface
… those demonstrated using velocity control, and neural control signal profiles revealed the monkeys actively accelerated and decelerated the cursor within a limited time window: 1-1.5 seconds). The fixed BCI decoding model was recast once again to control the force on a virtual cursor in a novel …

Androgen Regulation of Gene Expression Associated with Cell Growth and Neural Plasticity: Studies in Songbird Brain and the S115 Cell Line
… changes in genes likely be involved in neuronal plasticity. I cloned the canary homolog of the c-jun proto-oncogene, and confirmed its identity based on complete conservation of the important functional domains. I prepared RNA from steroid responsive parts of the brain from ovariectomized …

Neural systems supporting enhanced peripheral visual attention in deaf adults
Neural plasticity, the ability of neural tissue to adapt to a number of environments, is considered a defining characteristic of the brain. However, plasticity is poorly understood at the systems level. The exact limits of neural plasticity, which areas can adapt and what functions they can …

Mechanisms of sound localization in mammals: ageing, dynamics and adaption
… brain is also subject to developmental changes, neural plasticity constitutes a crucial factor enabling adaptation to a modified acoustic environment. My thesis comprises three studies, employing different techniques in three mammalian species, in which I provide evidence that adaptation …

Assessing neurophysiological and behavioural outcomes of the proximal upper limb muscles in response to novel motor skill acquisition
… and movements, and provide a way to assess the neural consequences of ergonomic modifications on neural plasticity. This thesis found significant changes in neural activity, measured using somatosensory evoked potentials (SEPs) following a single session of motor training session with the …

Robotic technology to aid and assess recovery and learning in stroke patients
… similar because both exhibit activity- dependent neural plasticity. However, the impact of other factors unique to recovery such as re-acquisition of muscle strength and resolution of abnormal muscle tone confounds the validity of this assumption. By implementing an adaptive impedance controller …
