  1. 1. Neuroimaging Consciousness: What happens in the brain when we become aware of what we percieve?

    Författare :Johan Eriksson; Lars Nyberg; Martin Ingvar; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; psykologi;

    Sammanfattning : Although consciousness has been studied since the beginning of the history of psychology, how the brain implements consciousness is seen as one of the last great mysteries. This thesis investigates neural correlates of consciousness by measuring brain activity while specific contents of consciousness are defined and maintained. LÄS MER

  3. 2. The conscious brain : Empirical investigations of the neural correlates of perceptual awareness

    Författare :Johan Eriksson; Lars Nyberg; Geraint Rees; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; consciousness; visual perception; object identification; functional neuroimaging; top-down processing; prefrontal cortex; auditory perception; Neuroscience; Neurovetenskap;

    Sammanfattning : Although consciousness has been studied since ancient time, how the brain implements consciousness is still considered a great mystery by most. This thesis investigates the neural correlates of consciousness by measuring brain activity with functional magnetic resonance imaging (fMRI) while specific contents of consciousness are defined and maintained in various experimental settings.

  4. 3. Partition and redemption : a Machiavellian analysis of Sami and Basque patriotism

    Författare :Johan Eriksson; Janerik Gidlund; Umeå universitet; []

    Sammanfattning : Since the end of the Second World War, the location of most interstate borders has been fixed.This suggests that the common phenomenon of ethnic groups partitioned by internationallyrecognized state borders is permanent. Nevertheless, a recurrent dream of 'redemption' (i.e. LÄS MER

  5. 4. Functional brain imaging of cognitive status in Parkinson's disease

    Författare :Urban Ekman; Johan Eriksson; Lars Nyberg; Lars Forsgren; Oury Monchi; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Parkinson’s disease; functional MRI; Mild cognitive impairment; Working memory; Parkinson’s disease dementia; BOLD;

    Sammanfattning : Parkinson’s disease (PD) is next to Alzheimer’s disease (AD) the second most common neurodegenerative disease. PD has traditionally been characterised as a motor disorder, but more recent research has revealed that cognitive impairments are frequent. LÄS MER

  7. 5. Functional brain imaging of sensorimotor dysfunction and restoration : investigations of discomplete spinal cord injury and deep brain stimulation for essential tremor

    Författare :Amar Awad; Johan Eriksson; Patric Blomstedt; Richard Levi; Lars Nyberg; Rick Helmich; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Sensorimotor control; fMRI; discomplete spinal cord injury; essential tremor; deep brain stimulation; cerebello-thalamo-cerebral circuit; Physiology; fysiologi; neurokirurgi; Neurosurgery; Neurology; neurologi; rehabiliteringsmedicin; Rehabilitation Medicine;

    Sammanfattning : The nervous system exists to generate adaptive behaviour by processing sensory input from the body and the environment in order to produce appropriate motor output, and vice versa. Consequently, sensorimotor dysfunction is the basis of disability in most neurological pathologies. LÄS MER
