  2. 21. Conformational Changes during Potassium-Channel Gating

    Author : Jakob Renhorn; Fredrik Elinder; David Engblom; Stephan Pless; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; ion-channel; electrophysiology; neuron; Jonkanal; neurologi; elektrofysiologi; neuron; aktionspotential;

    Abstract : Voltage-gated ion channels have a paramount importance in many physiological processes such as cell-to-cell communication, action potential-propagation, and cell motility. Voltage-gated ion channels are characterized by their ability to sense membrane voltage and to greatly change channel activity in response to small changes in the voltage. READ MORE

  4. 22. Cooling and dopamine

    Author : Roger Roscher; Anestesiologi och intensivvård; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Anaesthesiology; electrophysiology; cooling; Hypothermia; swine; lung transplantation; organ preservation; dopamine; circulation; contractility; oxygenation; intensive care; Anestesiologi; intensivvård;

    Abstract : There is little knowledge about the circulatory effects of dopamine in hypothermia. Induced hypothermia has been shown to improve outcome in various settings. Hypothermia is also used for preservation of organs that are harvested for transplantation. READ MORE

  5. 23. The role of cortico-basal ganglia systems in the construction of movement: Action selection and sequencing

    Author : Joel Sjöbom; Integrativ neurofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Electrophysiology; Voluntary movements; In-vivo; Motor Cortex; Corticostriatal; Basal Ganglia;

    Abstract : The cortico-basal ganglia system is instrumental in the construction of movement, through its involvement in aspects such as action selection, initiation/termination and sequencing, though the precise role of the different structures and how they collaborate on a network level to allow us to fluidly change from one behavior to another has long proven to be elusive.We have here recorded neuronal activity throughout the cortico-basal ganglia circuit in rats, in a series of projects in order to understand more about how some of these functions are controlled.

  6. 24. Neocortical interpretation of haptic and visual events across brain states: Electrophysiological investigations in sensory information processing

    Author : Sofie Skårup Kristensen; Hjärnans sensorimotoriska funktioner; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Haptics; Visual; Multisensory; Cortical; Rodent; Neurophysiology; Tactile; Electrophysiology;

    Abstract : This thesis delves into the complex architecture of dynamic sensory information processing in the neocortex. Specifically, it asks how primary sensory cortical regions are influenced by local and widespread cortical state changes. READ MORE

  7. 25. The Role of the Cortico-Basal Ganglia-System in Voluntary Movements

    Author : Martin Tamté; Integrativ neurofysiologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Neurophysiology; Electrophysiology; Pharmacology; Motor Systems; Voluntary movements; Philosophy; In vivo; Corticostriatal; Parkinson s disease; Dyskinesia; Levodopa; Multiple Electrode Arrays;

    Abstract : Bodies with multiple limbs and joints have endless possibilities to move around in their surrounding space. How the nervous system controls this amount of degrees of freedom in motor execution is a question under vigorous debate. READ MORE
