1. 1. On the Site of the Lesion in Konzo : Clinical and Neurophysiological Studies on a Non-Progressive Upper Motor Neuron Disorder

   Författare :Desire Tshala-Katumbay; Andrew Eisen; Uppsala universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurosciences; Konzo; upper motor neuron diseases; WHO criteria; electroencephalography; evoked potentials; brain involvement; Neurovetenskap; Neurology; Neurologi; Neurology; neurologi;

   Sammanfattning : Konzo is a permanent spastic para/tetraparesis occurring in undernourished populations in Africa relying on insufficiently processed bitter cassava, which contains cyanogenic compounds, as staple food. Its pathogenetic mechanism is unknown. Our studies aimed at clarifying the lesion in konzo. LÄS MER

3. 2. Electrophysiological correlates of consciousness

   Författare :Rasmus Eklund; Stefan Wiens; Mats Nilsson; Antti Revonsuo; Stockholms universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; neural correlates of consciousness; electroencephalography; event-related potentials; visual awareness negativity; auditory awareness negativity; recurrent processing; phenomenal consciousness; access consciousness; Psychology; psykologi;

   Sammanfattning : How does the brain enable us to experience seeing or hearing a stimulus? If a stimulus is repeatedly presented at the awareness threshold, subjects will report that they are aware of the stimulus on half of the presentations. Electroencephalography (EEG) can be used to non-invasively record neural activity as event-related potentials (ERPs). LÄS MER

4. 3. Sensorimotor function following anterior cruciate ligament injury : movement control, proprioception and neuropsychological perspectives

   Författare :Adam Grinberg; Charlotte Häger; Martin Björklund; Dario G. Liebermann; Clare Ardern; Umeå universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ACL; knee injury; sensorimotor control; proprioception; functional test; fear; anxiety; kinematics; electromyography; EMG; electroencephalography; EEG; brain; neuroplasticity; injury prevention; Sports Medicine; idrottsmedicin;

   Sammanfattning : Background: The high incidence of anterior cruciate ligament (ACL) injuries in sports suggests an involvement of both biomechanical and neurocognitive risk factors. Athletes are constantly exposed to challenging sports scenarios, which are often characterised by high-intensity movements combined with a multi-stimuli environment and continuous psychological pressure.

5. 4. Assessment of neurological prognosis after cardiac arrest – clinical and neurophysiological aspects

   Författare :Linus Lilja; Göteborgs universitet; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; cardiac arrest; neurological prognosis; prognostication; electroencephalography; somatosensory evoked potentials;

   Sammanfattning : Background: Post-resuscitation care after cardiac arrest in adults includes targeted temperature management (TTM) to mitigate secondary brain injury. The recommended target temperature is between 32°C and 36°C after a large, international, randomized trial showed comparable outcomes (33°C vs. 36°C). LÄS MER

7. 5. Age and Constraints on Language Learning : First Language Retention and Second Language Acquisition in International Adoptees

   Författare :Gunnar Norrman; Emanuel Bylund Spångberg; Guillaume Thierry; Janet Werker; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; bilingualism; critical period; electroencephalography; event-related potentials; first language retention; international adoption; phonology; second language acquisition; Bilingualism; tvåspråkighet;

   Sammanfattning : This thesis investigates the influence of age of acquisition on the long-term second language development of international adoptees. Because age of acquisition typically coincides with the onset of bilingualism, the study of maturational age effects in second language acquisition has been empirically and conceptually entangled with changes in language input and use.
