11. Brain functional near infrared spectroscopy in human infants : cerebral cortical haemodynamics coupled to neuronal activation in response to sensory stimulation
Sammanfattning : The assessment of cortical activation in the neonatal brain is crucial in the study of brain development, as it provides precious information for how the newborn infant processes external or internal stimuli. Thus far functional studies of neonates aimed to assess cortical responses to certain external stimuli are very few, due to the lack of suitable techniques to monitor brain activity of the newborn.

12. Prior knowledge and present events in the brain
Sammanfattning : Our experience the world is dependent on both the surroundings and the brain. In other words, perception is a synthesis of incoming signals, internal state, and previous knowledge rather than a mere reflection of the environment. LÄS MER
13. Investigating the multisensory representation of the hand and the space around it using fMRI
Sammanfattning : The human brain incessantly receives a staggering amount of information from all our senses. The dynamic integration of relevant multisensory signals is an evolutionarily optimal strategy to assist adaptive behavior. Arguably, one physical object stands out as the unique recipient of internal and external multisensory signals alike: the body. LÄS MER
14. Cognitive mechanisms in pain processing : assessed with functional imaging methods
Sammanfattning : The intensity and unpleasantness of a painful experience is often described as correlating well with the degree of noxious stimulation. However, the perception of pain is not a linear phenomenon, reflecting the signal from the peripheral neuron. Rather, the noxious input may be modulated at every level of the neural axis. LÄS MER
15. Pain and sensory function in HIV-infection : with and without antiretroviral therapy
Sammanfattning : Pain is a common symptom throughout the course of HIV-1 infection, with a prevalence ranging between 30-80%, varying with study methodology and patient selection. Neurogenic pain may appear as a consequence of distal predominantly sensory neuropathy (DSP), a common HIV-1 related neurological complication of late HIV-1 infection, usually during the AIDS-stage of the disease.
