Social stress in female mice: effects of differential housing on adrenocortical activity and the oestrous cycle
Thesis
(1980). Social stress in female mice: effects of differential housing on adrenocortical activity and the oestrous cycle

The general aim of this study has been to examine some physiological and behavioural aspects of crowding in mice. The notion of stress has been central to this study. Using Selye's General Adaptation Syndrome hypothesis as a framework, modern ideas o...

Isolation, purification and characterisation of the pentraxins from Limulus polyphemus and Mustelus canis
Thesis
(2008). Isolation, purification and characterisation of the pentraxins from Limulus polyphemus and Mustelus canis

CRP and SAP form part of the innate immune system in humans, and homologues have been found in mammals, amphibians, fish, elasmobranchs, and invertebrates. The aim of this research was to broaden knowledge of CRP and SAP in horseshoe crabs, and to at...

Stress and pituitary-adrenocortical manipulation during late pregnancy: effects upon offspring development in mice
Thesis
(1984). Stress and pituitary-adrenocortical manipulation during late pregnancy: effects upon offspring development in mice

This thesis describes the effects of crowding during the final third of pregnancy upon development of the offspring in mice, and examines the role of the pituitary-adrenocortical axis as the physiological mechanism of mediation.
In an attempt to con... Read More about Stress and pituitary-adrenocortical manipulation during late pregnancy: effects upon offspring development in mice.

Psychophysical evidence concerning the integration of curvature information in short contours
Thesis
(1980). Psychophysical evidence concerning the integration of curvature information in short contours

Performance of curvature discrimination was measured for a wide range of stimulus curvatures and sizes, using an adaptive version of the Method of Constant Stimuli. Performance is expressed both in terms of curvature difference thresholds, and effici...

A psychoacoustical study of the processing and subsequent detection of frequency-modulation
Thesis
(2020). A psychoacoustical study of the processing and subsequent detection of frequency-modulation

Evidence is provided for tuned channels in the human auditory system selectively responsive to frequency-modulation (FM). Thresholds for the detection of small changes in frequency were measured with a 2IFC procedure in two subjects at a number of fr...

Form specific adaptation and pattern recognition: an experimental and theoretical study
Thesis
(1981). Form specific adaptation and pattern recognition: an experimental and theoretical study

Among the theories of visual pattern recognition are structural theories which propose that patterns are encoded in terras of features and their spatial relationships (relations). Structural theories are examined here with both adaptation and pattern... Read More about Form specific adaptation and pattern recognition: an experimental and theoretical study.

The transcellular transport of immunoglobulin G in the rat and rabbit yolk sacs
Thesis
(1981). The transcellular transport of immunoglobulin G in the rat and rabbit yolk sacs

An in vitro method, previously described for incubating rat yolk sacs for short periods, was adapted for the incubation of rabbit yolk sacs. It was shown that the endocytic properties of these two tissues are very similar as judged by their rates of...

An investigation of some factors affecting the variability of the McCollough effect
Thesis
(1982). An investigation of some factors affecting the variability of the McCollough effect

A series of experiments are reported which have attempted to isolate some factors causing inter and intrasubject variability of the McCollough effect.* A number of such factors were found.
1. The initial strength of the OCCA is strongly influenced b... Read More about An investigation of some factors affecting the variability of the McCollough effect.

Spatial, temporal and chromatic properties of human scalp-recorded potentials evoked by patterned visual stimuli
Thesis
(1982). Spatial, temporal and chromatic properties of human scalp-recorded potentials evoked by patterned visual stimuli

A series of experiments are reported in which the spatial, temporal and chromatic properties of the initial components Cl and CII of the transient pattern-onset VEP, of predicted striate and extrastriate origin, are examined. Where relevant the respo... Read More about Spatial, temporal and chromatic properties of human scalp-recorded potentials evoked by patterned visual stimuli.

Echinococcus granulosus: studies on the development of the metacestode tegument.
Thesis
(1987). Echinococcus granulosus: studies on the development of the metacestode tegument

Protoscoleces of the horse strain of Echinococcus granulosus were successfully cultured both in vitro and in BALB/c mice to produce small hydatid cysts. In vitro cysts were formed from vesiculating protoscoleces and also from posterior bladders and p... Read More about Echinococcus granulosus: studies on the development of the metacestode tegument..

The effects of corticosterone on persistence of attention in Mus musculus
Thesis
(1987). The effects of corticosterone on persistence of attention in Mus musculus

It is widely believed that corticosterone plays a role in psychological, and ultimately behavioural adaptation during stress. The aim of this thesis was to examine the nature of the adaptation brought about by corticosterone. The hypothesis under tes...

Aspects of chromatic and temporal processing in normal and impaired human vision
Thesis
(1987). Aspects of chromatic and temporal processing in normal and impaired human vision

A psychophysical study was made of post-receptoral processing In the human visual system. The first series of experiments investigated normal red-green opponent-colour function by Means of a paradigm in which a white auxiliary field was made spatiall...

The effects of alcohols on pinocytosis and proteolysis in the rat yolk sac in vitro
Thesis
(1987). The effects of alcohols on pinocytosis and proteolysis in the rat yolk sac in vitro

This thesis Investigates the effects of two alcohols, ethanol and benzyl alcohol, on the process of endocytosis In the rat visceral yolk sac In vitro. In Chapter 1, the process of endocytosis is introduced and the structure and function of the rat vi...

Some studies of spontaneous and evoked acoustic emissions from the human ear
Thesis
(1987). Some studies of spontaneous and evoked acoustic emissions from the human ear

Several studies of spontaneous and evoked oto-acoustic emissions (SOAEs and EOAEs) and their relationship to norsal and pathological hearing mechanism are described.
1. A computer model was developed to study the theory that the EOAE is produced by... Read More about Some studies of spontaneous and evoked acoustic emissions from the human ear.
