Acknowledgements I have been fortunate enough to enjoy myself both at work and play whilst in Oxford. This is in no small part thanks to the great bunch of friends and colleagues who have helped gainfully occupy my time over the last three and more years. I am of course primarily grateful to SERC for my grant, my parents for their nancial help and not least to my supervisor, Edmund Rolls, who a...

Hemangiosarcomas are rare malignancies derived from blood vessel endothelium. In most cases, the origin of the tumor is difficult to be accurately determined due to poor cell differentiation. As far as skin is concerned, there are three clinical forms of the neoplasm: 1. Idiopathic hemangiosarcoma – most commonly located on the facial skin or scalp. 2. Hemangiosarcoma presented with limb edema ...

For 1 < p < oo we show that LP functions defined on a C°° totally real submanifold of C" can be locally decomposed into the sum of boundary values of holomorphic functions in wedges such that the boundary values are in LP . The general case of a C°° totally real submanifold is reduced to the flat case of R" in C" by an almost analytic change of variables. LP results in the flat case are then ob...

The representation of objects and faces by neurons in the temporal lobe visual cortical areas of primates has the property that the neurons encode relatively independent information in their firing rates. This means that the number of stimuli that can be encoded increases exponentially with the number of neurons in an ensemble. Moreover, the information can be read by receiving neurons that per...

The responses of single neurons provide evidence that is essential to understanding what information is encoded in a brain area, and how it is encoded, for the information conveyed by a single neuron is almost independent of that conveyed by others in the same population. The differences in the firing rate response profiles of single neurons to a set of stimuli or events encode most of the info...

OVERVIEW OF ADULT HIPPOCAMPAL NEUROGENESIS The dentate gyrus represents a unique system for the study of interactions between neuronal development and experience. While this hippocampal subfield has been extensively investigated in relationship to the ongoing process of adult neurogenesis, the mnemonic contributions of mature granule neurons have remained enigmatic. Much of the rationale for fo...

Blended learning, the combination of traditional face-to-face teaching methods with authentic on-line learning activities, has the potential to transform student learning experiences and outcomes. In spite of this advantage, university teachers often find it difficult to adopt new online techniques, in part because institutional practices are still geared to support more traditional approaches....

Joyce K., aged 6, is the tenth of 12 children. The remainder of the family are healthy and there is no family history of any condition suggesting neurofibromatosis. Birth was normal and infancy uneventful, but the mother noticed a large and slightly protruding tongue when she first saw the child a few hours after birth. She had gastro-enteritis at 6 months, but apart from this had no serious il...
