Sammanfattning : We perceive the environment via sensor arrays and interact with it through motor outputs. The work of this thesis concerns how the brain selects actions given the information about the perceived state of the world and how it learns and adapts these selections to changes in this environment.

Sammanfattning : Huntington’s disease (HD) is a fatal, hereditary disorder caused by a mutation in the gene encoding the protein huntingtin. Although mutant huntingtin is ubiquitously expressed throughout the body, HD research has mainly focused on the role of the basal ganglia. LÄS MER
Sammanfattning : The motor nervous system is one of the main systems of the body and is our principle means ofbehavior. Some of the most debilitating and wide spread disorders are motor systempathologies. In particular the basal ganglia are complex networks of the brain that control someaspects of movement in all vertebrates. LÄS MER
Sammanfattning : A major challenge in the field of neuroscience is to link behavior with specific neuronal circuitries and cellular events. One way of facing this challenge is to identify unique cellular markers and thus have the ability to, through various mouse genetics tools, mimic, manipulate and control various aspects of neuronal activity to decipher their correlation to behavior.

Sammanfattning : Anatomical regions and how we define boundaries between and within structures in the brain put a constraint on our understanding of the brain. More than a century of research on the brain has revealed its fundamental organization to be based on single nerve cells communicating through electrical signals over chemical synapses. LÄS MER
