1. Endoplasmic reticulum function in dendrites and dendritic spines of hippocampal neurons
Abstract : In the hippocampus, dendritic spines are compartmentalized postsynaptic micro-domains in the excitatory synapse. Subsets of bigger and mushroom-shaped hippocampal dendritic spines contain tubules and cisterns of endoplasmic reticulum (ER) that are connected to the soma and dendrites of the neuron. READ MORE

2. Death, survival, and morphological development of hippocampal granule cells born in an inflammatory environment
Abstract : The brain continues to form new neurons throughout life. This process of adult neurogenesis has been thoroughly documented in several species including birds, rodents and humans. READ MORE

3. The paralemmin protein family : Phosphoproteins involved in filopodia and dendritic spine formation
Abstract : Dendritic spines, which connect neurons with each other, constitute most of the excitatory synapses and undergo experience-dependent neuronal plasticity. The function of dendritic spines and their synaptic strength are highly correlated with morphological changes. READ MORE

4. Plasticity in the dopamine 1 receptor system : behavior and cell biological studies
Abstract : Dopamine is a key neurotransmitter in the brain, and has an important modulatory role in the control of motor activity and cognitive processes. Dysfunctions of the dopamine system have been implicated in several neuropsychiatric disorders such as schizophrenia and attention-deficit/hyperactivity disorder. READ MORE

5. Mathematical Models in Cellular Biophysics
Abstract : Cellular biophysics deals with, among other things, transport processes within cells. This thesis presents two studies where mathematical models have been used to explain how two of these processes occur. Cellular membranes separate cells from their exterior environment and also divide a cell into several subcellular regions. READ MORE
