Abstract:

The formation of patterns of functionally appropriate chemical synapses is one of the key aspects of nervous system development. I have investigated the cellular interactions that culminate in the formation of an inhibitory synapse between the R and P neurons of the leech. These neurons may be isolated and maintained in culture, where they reform synaptic connections under easily manipulable conditions. An early event in the formation of this synapse is the loss from sites of contact in the postsynaptic P cell of an excitatory response to the transmitter serotonin. The loss of this response wa

The objective of this research was to investigate the use of leeches as in situ monitors of the biological availability of chlorophenols and degree of contamination in the North Arm of the Fraser River Estuary, British Columbia, where chlorophenols are used as wood preservatives by several forest industry operations. The objective was accomplished by : 1) an integrated series of grab and continous samples to determine the spatial and temporal variability in chlorophenol contamination, 2) in situ and laboratory experiments to compare leech bioconcentration to water levels of pollutants and to d

Haematophagous, metazoan ectoparasites and protozoan blood parasites of intertidal fishes from Wales and South Africa formed the main focus of this study.

These taxonomically distinct ectoparasites were suspected vectors of the blood protozoans, and the latter were mostly apicomple{(ans of the genus Haemogregarina and euglenozoans ofthe genus Trypanosoma.

The majority of such records were for fish from lakes and rivers, but a few records from waterfowl were also reported. Simple laboratory experiments demonstrated that a wide range of invertebrate and vertebrate predators may feed on both adult and young leeches. F

Abstract:

There are forty registered organophosphates in the United States and they range from pesticides and insecticides to nerve agents or neurotoxins such as sarin. Organophosphates (OP’s) have been used in chemical warfare for years and tend to lead to death due to an attack on the nervous system. Chemical assays and mass microscopy have been used to assess the concentration of OP’s in the environment, but both methods require the body to metabolize the OP first, which can be detrimental to the victim. It is crucial to come up with a method to investigate and detect these neurotoxins without cau

The control of the number of segments is a problem posed in all segmented phyla: how can there be generation of a constant number of body parts? Here I have studied the leech embryo as an example of an animal where the number of segments is regulated. The leech develops in a stereotypical manner and gives rise, during the cleavage stage, to 5 pairs of teloblasts. These cells divide in a stem-cell manner, producing blast cells, the founders of the segmental body plan. The blast cells are produced one after the other, and stay ordered in such a way that the most anterior blast cells are the olde

Each motor neuron receives a specific pattern of inhibitory input from rhythmic premotor heart interneurons and translates this spatiotemporal pattern into the fictive heartbeat motor pattern.

Abstract:

In both vertebrates and invertebrates, including leeches, microglia are rapidly activated by central nervous system (CNS) damage and migrate to the lesions. Adenosine triphosphate (ATP), nitric oxide (NO) and endocannabinoids have been implicated in controlling activation and migration, but details of the mechanisms are uncertain. This dissertation tests the hypothesis that endocannabinoids coordinate and influence the microglial response to nerve cord crushing. Chapter 1 reports that application of endocannabinoids to nerve cords at concentrations as low as 100 nM for arachidonylethanolamide

Abstract:

A well documented laboratory setup, leech preparation process, and bio-potential data recording process are needed. Repeatability and quality data recordings are essential and thus dictate the requirements of the laboratory setup and processes listed above. Advances in technology have both helped and hindered this development. While very precise equipment is required to record the low voltage bio-potentials, noisy electronic equipment and wires surrounding the work area provide high levels of interference. Proper laboratory setup and data recording processes, however, limit the unwanted in
