21. Computational Approaches to the Degeneration of Brain Networks and Other Complex Networks
Sammanfattning : Networks are ubiquitous with several levels of complexity, configuration, hierarchy and function. Many micro- and macro-scale biological or non-biological interactions define complex systems. LÄS MER
22. Physiology and Pharmacology of GABAA receptors: The Brakes in the Brain
Sammanfattning : Inhibitory neurotransmission in the brain is mostly mediated by gamma-aminobutyric acid type A (GABAA) receptors. These receptors are involved in both phasic inhibition (point-to-point inhibition, synaptic transmission) and tonic inhibition (diffuse form of inhibition, brain homeostasis). LÄS MER
23. Random geometric graphs and their applications in neuronal modelling
Sammanfattning : Random graph theory is an important tool to study different problems arising from real world.In this thesis we study how to model connections between neurons (nodes) and synaptic connections (edges) in the brain using inhomogeneous random distance graph models. LÄS MER
24. Developmental plasticity of the glutamate synapse: Roles of low frequency stimulation, hebbian induction and the NMDA receptor
Sammanfattning : The glutamate synapse is by far the most common synapse in the brain and acts via postsynaptic AMPA, NMDA and mGlu receptors. During brain development there is a continuous production of these synapses where those partaking in activity resulting in neuronal activity are subsequently selected to establish an appropriate functional pattern of synaptic connectivity while those that do not are elimimated.

25. Plasticity of the developing glutamate synapse in the hippocampus
Sammanfattning : Synapses are highly plastic, i.e. they have the ability to change their signaling strength both in the short- and long-term (e.g. LÄS MER
