1. To select one hand while using both : neural mechanisms supporting flexible hand dominance in bimanual object manipulation
Sammanfattning : 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. LÄS MER
2. The effect of intermittent theta-burst stimulation over the dorsomedial prefrontal cortext on brain activity in depression
Sammanfattning : Repetitive transcranial magnetic stimulation is an emerging alternative for treatment-resistant depression, with ongoing developments in stimulation protocols and treatment targets. As such, intermittent theta-burst stimulation (iTBS) delivered over the dorsomedial prefrontal cortex (dmPFC) has shown promise, however establishing a need for neuroimaging studies to further understand the treatment mechanisms.

3. Negative symptoms, repetitive transcranial magnetic stimulation and heart rate variability in schizophrenia and depression
Sammanfattning : Negative symptoms comprise anhedonia, avolition, and blunted affect. Although first described in schizophrenia, these symptoms share phenomenology with the depressive state. Pharmacological treatment has not been successful in reducing negative symptoms. LÄS MER
4. Brain Plasticity and Upper Limb Function After Stroke: Some Implications for Rehabilitation
Sammanfattning : 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. LÄS MER
5. Amyotrophic lateral sclerosis (ALS) associated with superoxide dismutase 1 (SOD1) mutations in British Columbia, Canada : clinical, neurophysiological and neuropathological features
Sammanfattning : 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. LÄS MER
