Fall 2013
Glomus cells of the carotid body are peripheral chemoreceptors that detect changes in arterial oxygen levels. Hypoxia suppresses oxygen-sensitive K+ channels in glomus cells, resulting in cytosolic Ca2+ ([Ca2+]i) elevation in glomus cells via the activation of voltage-gated Ca2+ channels. The...

Influence of lipids (arachidonic acid and cholesterol) on calcium signalling in rodent pancreatic beta cells
DownloadFall 2010
Ca2+ is an important mediator of stimulus-secretion coupling in beta cells of the pancreatic islets, which secrete insulin in response to elevation in plasma glucose concentration. I studied the actions of two lipids, arachidonic acid (AA) and cholesterol, on enzymatically-dissociated single...

The reason and functional relevance of why we sleep continues to perplex researchers. One fundamental reason behind why sleep remains a mystery is because it is challenging to study given how easily it is disrupted. Anesthesia has been suggested to be a model for studying sleep given the...

The effect of long-term interleukin-1 beta exposure on sensory neuron electrical membrane properties: implications for neuropathic pain
DownloadSpring 2011
The effect of interleukin-1 beta (IL-1β) on the electrical properties of sensory neurons was assessed at comparable levels and exposure times to those found in animal models of neuropathic pain. Experiments involved whole cell current- or voltage-clamp recordings from rat dorsal root ganglion...

An individual’s body weight is tightly regulated by balancing food intake with energy expenditure. This is accomplished in part by secretion of the hormone leptin by adipocytes, an excess of which signals to reduce appetite and increase activity through action in the hypothalamic region of the...

Calcium Imaging and Field Potential Analysis of Autocrine Neuromodulation in the Locus Coeruleus of Newborn Rat Brain Slices
DownloadFall 2022
The locus coeruleus (LC) is a small brainstem nucleus that controls diverse behaviours and brain functions via release of noradrenaline (NA) in the neonatal time period. There is increasing evidence of complexity in this neuron-astrocyte ‘neural’ network that remains mostly unexplored in...

Antagonistic modulation of spontaneous neural network activities in isolated newborn rat brainstem preparations by opioids and methylxanthines
DownloadFall 2012
Apnea of prematurity is a common problem among the infants born before term pregnancy. Administration of respiratory stimulating drugs methylxanthines is the most frequent therapy, often in combination with the use of intubation. Opioids are used to reduce the pain associated with intubation,...

Fall 2023
Sleep is a vital neurobiological process, yet despite its fundamental significance, delineating the endogenous neural pathways involved has been slow to progress due to a lack of diverse sleep models. Anesthesia, which has direct behavioural parallels to natural sleep, and which is often linked...

Modulation of Spontaneous Neural Network Bursting in Newborn Rat Brain Slices by Extracellular Calcium, Methylxanthines, and Opioids
DownloadFall 2012
Spontaneous neuronal bursting appears to be pivotal for brain maturation. This thesis studied such synchronized neural network oscillations in immature newborn rat hippocampus, cortex, and locus coeruleus. For this, horizontal brain slices were generated for (simultaneous) suction electrode...
