Abstract:
1. Electrical characteristics of the cell body of an identified motoneurone, the 'fast' coxal depressor motoneurone (Df), from the cockroach (Periplaneta americana) have been studied under current- and voltage-clamp. 2. In response to low magnitude, relatively long duration depolarising current pulses, Df could generate plateau potentials, regenerative events which often far outlived the duration of the applied depolarisation. 3. Plateau potentials constitute an inherent property of the neurone because they could be evoked in somata that had been surgically isolated from other parts of the neu

Abstract:
The correct polarity of a neuron underlies its ability to integrate precise circuitries in the nervous system. The goal of my thesis was to investigate the pathways that establish and maintain neuron polarity/orientation in vivo. To accomplish this, I used bipolar VC4/5 motor neurons, which innervate the C. elegans egg-laying musculature, as a model system. Vulval proximal VC4/5 neurons extend axons in the left-right (LR) orientation, around the vulva; whereas vulval distal VC1-3,6 neurons extend axons along the anterior-posterior (AP) axis.

Abstract:
The overall aim of this thesis was to establish strategies to minimize secondary damage to the injured spinal cord. Secondary damage that follows spinal cord injury (SCI) involves inflammatory and excitotoxic pathways. Regulation of these pathways using immunomodulatory and neuroprotective substances potentially protects the injured spinal cord from further damage. We also developed and studied resorbable biomaterials to be used as carriers for potential neuroprotectants to the injured spinal cord. We used transversal spinal cord slice cultures (SCSCs) derived from postnatal mice as a model. S
