  1. 1. Amyotrophic lateral sclerosis (ALS) associated with superoxide dismutase 1 (SOD1) mutations in British Columbia, Canada clinical, neurophysiological and neuropathological features

    University dissertation from Umeå : Farmakologi och klinisk neurovetenskap

    Author : Heather G. Stewart; Umeå universitet.; [2005]
    Keywords : ALS; SOD1; complete penetrance; incomplete penetrance; mis-diagnosis; upper motor neuron; clinical neurophysiology; transcranial magnetic stimulation; peristimulus time histogram; corticospinal pathway; cortical inhibition; cortical hyper-excitability;

    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. 2. The role of striatal inhibition in the processing of cortical neuronal avalanches

    University dissertation from Stockholm : Karolinska Institutet, Dept of Neuroscience

    Author : Andreas Klaus; Karolinska Institutet.; Karolinska Institutet.; [2013]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

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

  3. 3. Propofol changes the cytoskeletal function in neurons An experimental study in cortical cultures

    University dissertation from Linköping : Linköping University Electronic Press

    Author : Dean Turina; Linköpings universitet.; Linköpings universitet.; Östergötlands Läns Landsting.; [2012]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Propofol; cytoskeleton;

    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.

  4. 4. Stroke and Functional Recovery - An experimental study on environmental influence and gene expression after cortical infarcts in the rat

    University dissertation from Anette Risedal, Neurologiska kliniken, 221 85, Lunds Universitetssjukhus, Lund, Sverige

    Author : Anette Risedal; Lund University.; Lunds universitet.; [2004]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurology; neuropsychology; cortical infarct; rat; enriched environment; functional recovery; brain-derived neurotrophic factor; inducible transcription factors; neuropsykologi; neurofysiologi; Neurologi; glucocorticoids; neurophysiology;

    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

  5. 5. Hypothalamic and cortical control of jaw reflexes

    University dissertation from Umeå : Umeå universitet

    Author : Kurt Å. Olsson; Umeå universitet.; [1979]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cat; Oral projections; Cerebral cortex; Cytoarchitecture; Hypothalamus; Defence-Attack area; Jaw reflexes; Bruxism; Myofascial pain dysfunction;

    Abstract : The subject of the thesis is a study of the projections from low threshold oral and face afferents to the cerebral cortex and of descending motor control mechanisms originating in the cerebral cortex or the hypothalamus and influencing the jaw reflexes.Cats anaesthetized with chi oral ose were used for the experiments.
