1. Imaging the molecular pathways of neurodegeneration : New pathologies of SCA7
Sammanfattning : Spinocerebellar Ataxia type 7 (SCA7) is a genetic neurodegenerative disease with lethal outcome that affects the cerebellum and retina of patients. This thesis focuses on characterising molecular pathological pathways that cause toxicity and cell death in SCA7. LÄS MER
2. Studies of Spinal Motor Control Networks in Genetically Modified Mouse Models
Sammanfattning : Spinal neurons are important in several aspects motor control. For example, the neurons essential for locomotor movements reside in the ventral spinal cord. In this thesis, different motor control functions are being related to neuronal populations defined by their common expression of a gene. LÄS MER
3. 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
4. Generation of Dopaminergic Neurons from Human Embryonic Stem Cells
Sammanfattning : Since the first successful derivation of human embryonic stem cells (hESC), rapid progress has been attained in the development of strategies in differentiation of these cells into various neural lineages, with the fundamental objective of using these cells for replacement and repair of damaged neuronal circuits in the central nervous system (CNS). Of particular interest are midbrain dopaminergic (mDA) neurons, which play a central role in regulation of voluntary movement. LÄS MER
5. Neural Control of Movement : Motor Neuron Subtypes, Proprioception and Recurrent Inhibition
Sammanfattning : Movement is central for life, and all animals depend on accurate regulation of movement for purposeful behavior. There is great diversity of movements, ranging between simple and vital breathing movements to minute and subtle movements of the face used to communicate emotions. LÄS MER
