  2. 1. Chloride Homeostasis in Central Neurons

    Author : Tushar Yelhekar; Staffan Johansson; Michael Druzin; Merab Kokaia; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; chloride concentration; current-voltage relation; interpolation; voltage ramp; reversal potential; [Cl–]i recovery; KCC2; extracellular matrix; GABAA receptor; chloride leak conductance; neurosteroid; fysiologi; Physiology;

    Abstract : The overall aim of the present thesis is to clarify the control of intracellular chloride homeostasis in central neurons, because of the critical role of chloride ions (Cl–) for neuronal function. Normal function of the central nervous system (CNS) depends on a delicate balance between neuronal excitation and inhibition. READ MORE

  4. 2. Generation of Dopaminergic Neurons from Human Embryonic Stem Cells

    Author : Tandis Vazin; Joakim Lundeberg; Ernest Arenas; KTH; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Human; dopaminergic; embryonic stem cells; differentiation; stromal cells; PA6 cells; dopamine; neurons; Neuroscience; Neurovetenskap; Neurobiology; Neurobiologi; Molecular neurobiology; Molekylär neurobiologi;

    Abstract : 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. READ MORE

  5. 3. GABA-, glycine- and glutamate-induced currents in rat medial preoptic neurons : functional interactions and modulation by capsaicin

    Author : Urban Karlsson; Staffan Johansson; Johannes Krupp; Bryndis Birnir; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; medial preoptic nucleus; synaptic transmission; glutamate; GABA; glycine; TRPV1; Physiology; Fysiologi;

    Abstract : The medial preoptic nucleus (MPN) of the hypothalamus plays a major role in many functions involved in maintaining bodily homeostasis, such as thermoregulation and osmoregulation, as well as in the control of complex behaviours, e.g. sexual behaviour. READ MORE

  6. 4. Studies of Spinal Motor Control Networks in Genetically Modified Mouse Models

    Author : Henrik Gezelius; Klas Kullander; Ted Ebendal; Martyn Goulding; Uppsala universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; acetyl choline; central nervous system; central pattern generator; Cre recombinase; development; genetic screen; glutamate; interneuron; motor neuron; mouse; mouse genetics; movement; network; neuronal network; nicotinic receptors; physiology; Renshaw cell; rhythm; spinal cord; transmitter; Neuroscience; Neurovetenskap; Neurobiology; Neurobiologi; Molecular neurobiology; Molekylär neurobiologi; Neurophysiology; Neurofysiologi; Neurobiology; Neurobiologi; medicinsk utvecklings- och neurobiologi; Developmental Neurosciences;

    Abstract : 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. READ MORE

  7. 5. Neural circuits engaged in mastication and orofacial nociception

    Author : Tuija Athanassiadis; K-G Westberg; Sten Grillner; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; rhythmical jaw movements; central pattern generator; trigeminal system; rabbit; Rat; c-Fos; nociceptors; muscle pain; muscle spindle afferents; glutamate; Neurophysiology; Neurofysiologi; fysiologi; Physiology;

    Abstract : A deeper understanding of both movement control and the effects of nociceptor inputs on our motor systems is critical for proper clinical diagnosis of musculo-skeletal dysfunctions and for development of novel rehabilitation schemes. In the jaw system, masticatory movements are produced by a central pattern generator (CPG) located in the brainstem. READ MORE
