1. Amyotrophic lateral sclerosis (ALS) associated with superoxide dismutase 1 (SOD1) mutations in British Columbia, Canada : clinical, neurophysiological and neuropathological features
Abstract : Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disorder characterized by loss of motor neurons and their supporting cells in the brain, brainstem and spinal cord, resulting in muscle paresis and paralysis including the bulbar (speech, chewing, swallowing) and respiratory muscles. The average age at onset is 55 years, and death due to respiratory failure occurs 2-5 years after symptom onset in ~ 85% of cases. READ MORE

2. The role of striatal inhibition in the processing of cortical neuronal avalanches
Abstract : The brain is spontaneously active even in the absence of any obvious motor actions or sensory perceptions. This so-called resting activity or ongoing activity reflects the myriads of neuronal interactions necessary for the brain to process past actions, allow for current inputs, and prepare for future decisions and responses.

3. Defense-related inhibition of sympathetic nerve activity: Insights from neuroimaging and monozygotic twins on related cortical processes and clinical potential
Abstract : This thesis investigates a physiological phenomenon observed in the peripheral sympathetic nervous system in response to various stressors and tries to bring it closer to clinical research. Sudden surprising stimulation can evoke a transient inhibition of sympathetic nerve activity to blood vessels in the human body which is also predictive of the blood pressure response. READ MORE

4. Propofol changes the cytoskeletal function in neurons : An experimental study in cortical cultures
Abstract : Every day, general anaesthetics are given to a large number of patients around the world but the cellular mechanisms of how anaesthetics act are still not clear. General anaesthetics cause the intended unconsciousness, amnesia and immobility in patients, but also side effects such as a decrease in mean arterial pressure and arrhythmia, both of which contribute to complications such as heart damage and stroke.

5. Stroke and Functional Recovery - An experimental study on environmental influence and gene expression after cortical infarcts in the rat
Abstract : Abstract Stroke is the third leading cause of death in the western world, and the number one cause of disability. 85% of all strokes are ischemic. Most stroke survivors will experience recovery of function. The mechanisms behind this improvement are partly unknown, but may involve elements of both compensation and restoration. READ MORE
