  1. 1. To select one hand while using both neural mechanisms supporting flexible hand dominance in bimanual object manipulation

    University dissertation from Umeå : Umeå university

    Author : Anna Theorin; Roland Johansson; Fredrik Ullén; [2009]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; object manipulation; bimanual coordination; action selection; cerebral cortex; functional laterality; humans; hand; magnetic resonance imaging; transcranial magnetic stimulation; electromyography; MEDICINE Physiology and pharmacology Physiology; MEDICIN Fysiologi och farmakologi Fysiologi; fysiologi; Physiology;

    Abstract : In daily activities, the brain regularly assigns different roles to the hands dependingon task and context. Yet, little is known about the underlying neural processes. Thiscertainly applies to how the brain, where each hemisphere primarily controls onehand, manages the between-hand coordination required in bimanual objectmanipulation. READ MORE

  2. 2. Brain Plasticity and Upper Limb Function After Stroke: Some Implications for Rehabilitation

    University dissertation from Uppsala : Rehabiliteringsmedicin

    Author : Påvel Lindberg; Uppsala universitet.; [2007]
    Keywords : Neurosciences; Stroke; Upper Limb; Brain Plasticity; Functional MRI; Diffusion Tensor Imaging; Transcranial Magnetic Stimulation; Neurovetenskap;

    Abstract : Neuroimaging and neurophysiology techniques were used to study some aspects of cortical sensory and motor system reorganisation in patients in the chronic phase after stroke. Using Diffusion Tensor Imaging, we found that the degree of white matter integrity of the corticofugal tracts (CFT) was positively related to grip strength. READ MORE

  3. 3. 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; Hiroshi Mitsumoto; [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

  4. 4. Neural control of standing posture

    University dissertation from Stockholm : Karolinska Institutet, Department of Neuroscience

    Author : Craig Tokuno; Karolinska Institutet.; Karolinska Institutet.; [2007]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Posture; motor cortex; electromyography; kinematics; H-reflex; pre-synaptic inhibition; transcranial magnetic stimulation;

    Abstract : When humans are asked to stand normally, they are not completely motionless. Rather, small amounts of body movement, termed postural sway, can be observed. Although the postural sway of standing has been well described, the manner in which this sway is neurally controlled and its influence in tasks involving postural re-stabilization are not known.

  5. 5. Language as structured sequences: a causal role of Broca's region in sequence processing

    University dissertation from Stockholm : Karolinska Institutet, Dept of Clinical Neuroscience

    Author : Julia Uddén; Karolinska Institutet.; Karolinska Institutet.; [2012]

    Abstract : In this thesis I approach language as a neurobiological system. I defend a sequence processing perspective on language and on the function of Broca's region in the left inferior frontal gyrus (LIFG). This perspective provides a way to express common structural aspects of language, music and action, which all engage the LIFG. READ MORE
