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,...

The goal of this thesis is to investigate the biophysical basis underlying the nonlinear relationship between firing response and current stimulation in single motor neurons. After reviewing the relevant motoneuron physiology and theories that describe complex dendritic signaling properties, I...

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...

The roles of Pbx and Meis TALE-class homeodomain transcription factors in vertebrate neural patterning
DownloadFall 2010
One of the major goals of developmental biology is to understand how specialized groups of cells arise from an initially unspecified cell population. The vertebrate hindbrain is transiently segmented along its anterior-posterior axis into lineage-restricted compartments called rhombomeres, making...
