1. Machine learning for identification of brain activity patterns with applications in gentle touch processing
Sammanfattning : Since the first mention of artificial intelligence in the 1950s, the field of machine learning has provided increasingly appealing tools for recognition of otherwise unintelligible pattern representations in complex data structures. Human brain activity, acquired using functional magnetic resonance imaging (fMRI), is a prime example of such complex data where the utility of pattern recognition has been demonstrated in a wide range of studies recently (Haynes et al.

2. The subthalamic nucleus in motor and affective functions : An optogenetic in vivo-investigation
Sammanfattning : The basal ganglia form a group of subcortical interconnected nuclei involved in motor, limbic and cognitive functions. According to the classical model of the basal ganglia, two main pathways exert opposing control over movement, one facilitating movement and the other suppressing movement. LÄS MER
3. Functional Analysis of the Vesicular Glutamate Transporter 2 in Specific Neuronal Circuits of the Brain
Sammanfattning : A key issue in neuroscience is to determine the connection between neuronal circuits and behaviour. In the adult brain, all neuronal circuits include a glutamatergic component. LÄS MER
4. Positron Emission Tomography (PET) Studies in Anxiety Disorders
Sammanfattning : Anxiety disorders are very common and the primary feature is abnormal or inappropriate anxiety. Fear and anxiety is often mediated by the amygdala, a brain structure rich in substance P (SP) and neurokinin 1 (NK1) receptors. LÄS MER
5. Molecular Adaptations in the Endogenous Opioid System in Human and Rodent Brain
Sammanfattning : The aims of the thesis were to examine i) whether the endogenous opioid system (EOS) is lateralized in human brain areas involved in processing of emotions and pain; ii) whether EOS responses to unilateral brain injury depend on side of lesion, and iii) whether in human alcoholics, this system is involved in molecular adaptations in brain areas relevant for cognitive control of addictive behavior and habit formation.The main findings were that (1) opioid peptides but not opioid receptors and classic neurotransmitters are markedly lateralized in the anterior cingulate cortex involved in processing of positive and negative emotions and affective component of pain.
