  2. 1. Dealing with Digits : Arithmetic, Memory and Phonology in Deaf Signers

    Author : Josefine Andin; Mary Rudner; Jerker Rönnberg; Örjan Dahlström; Lars Nyberg; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Adult deaf signers; phonology; arithmetic; short-term memory; working memory; neuro imaging; Vuxna teckenspråkiga döva; fonologi; aritmetik; korttidsminne; arbetsminne; hjärnavbildning;

    Abstract : Deafness has been associated with poor abilities to deal with digits in the context of arithmetic and memory, and language modality-specific differences in the phonological similarity of digits have been shown to influence short-term memory (STM). Therefore, the overall aim of the present thesis was to find out whether language modality-specific differences in phonological processing between sign and speech can explain why deaf signers perform at lower levels than hearing peers when dealing with digits.

  4. 2. ­­­Visual assessment of perfusion and metabolism in neurodegenerative dementia

    Author : David Fällmar; Elna-Marie Larsson; Lena Kilander; Mark Lubberink; Ian Law; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Dementia; Neurodegenerative; Brain imaging; Diagnostics; Neuroradiology; Neuroimaging; Demens; Neurodegenerativ; Hjärnavbildning; diagnostik; Neuroradiologi; Neuroimaging; Radiology; Radiologi;

    Abstract : A worldwide demographic shift is currently occurring, with rapidly increasing numbers of elderly individuals. Since the incidence of neurodegenerative disease generally increases with age, this entails an increase in dementia prevalence. READ MORE

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

    Author : Amar Awad; Johan Eriksson; Patric Blomstedt; Richard Levi; Lars Nyberg; Rick Helmich; Umeå universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  6. 4. Restructuring the socially anxious brain : Using magnetic resonance imaging to advance our understanding of effective cognitive behaviour therapy for social anxiety disorder

    Author : Kristoffer N. T. Månsson; Gerhard Andersson; Tomas Furmark; Per Carlbring; C-J Boraxbekk; Philippe Goldin; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Social anxiety disorder SAD ; Cognitive behaviour therapy CBT ; Amygdala; Multimodal neuroimaging; Support vector machine learning SVM ; Social ångest; Kognitiv beteendeterapi; Hjärnavbildning; Amygdala; Magnetresonanstomografi;

    Abstract : Social anxiety disorder (SAD) is a common psychiatric disorder associated with considerable suffering. Cognitive behaviour therapy (CBT) has been shown to be effective but a significant proportion does not respond or relapses, stressing the need of augmenting treatment. READ MORE

  7. 5. Human brains and virtual realities : Computer-generated presence in theory and practice

    Author : Daniel Sjölie; Lars-Erik Janlert; Johan Eriksson; Giuseppe Riva; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Human brain function; virtual reality; presence; cognitive neuroscience; human-computer interaction; brain imaging; fMRI; BCI; neural correlates; HCI theory; reality-based interaction.;

    Abstract : A combined view of the human brain and computer-generated virtual realities is motivated by recent developments in cognitive neuroscience and human-computer interaction (HCI). The emergence of new theories of human brain function, together with an increasing use of realistic human-computer interaction, give reason to believe that a better understanding of the relationship between human brains and virtual realities is both possible and valuable.
