  1. 1. Transducer properties of a mechanoreceptor : an electrophysiological and pharmacological study of the crayfish stretch receptor

    Författare :Jiahui Lin; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :stretch receptor; Na channels; K channels; local anesthetics; calmodulin antagonist; patch clamp; voltage clamp;

    Sammanfattning : The abdominal stretch receptor organ of the crayfish, an analog to the human muscle spindle, contains one slowly adapting (SA) and one rapidly adapting (RA) receptor neuron. The general aims of this project were to elucidate, in the SA and RA neurons, the participation of voltagegated Na+ and K+ channels in overall transducer process and adaptation, and to study possible blocking agents specific to mechanosensitive (MS) channels.

  2. 2. Expression and function of TRP channels in peripheral sensory neurons

    Författare :Susanne Staaf; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Transient receptor potential (TRP) channels comprise a family of multifunctional proteins which has since its discovery been of particular interest in sensory biology even though they are also frequently expressed in non-neuronal cell types. It is evident that TRP channels play an important role in the function of sensory neurons, not at least by being sensors of external stimuli. LÄS MER

  3. 3. Mechanisms of adaptation in a mechanoreceptor : a study of mechanical and ionic factors in the crayfish stretch receptors

    Författare :Nuhan Purali; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Crayfish; stretch receptor; adaptation; visco-elastic properties; mechanosensitive channels; potassium channels; sodium channels; gadolinium; tetraethylammonium chloride; 4-amino pyridine; scorpion venom Leiurus quinquestrialus;

    Sammanfattning : The stretch receptor organ of the crayfish, an analog to the human muscle spindle, is a unique preparation for the study of mechanotransduction. The organ consists of a rapidly and a slowly adapting receptor each composed of a receptor muscle fibre into which inserts the dendrites of a multipolar sensory neuron. LÄS MER

  4. 4. Neuronal mechanisms of feedback postural control

    Författare :Li-Ju Hsu; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :postural control; equilibrium; body configuration; reticulospinal neurons; stretch receptor neurons; galvanic vestibular stimulation; artificial feedback; locomotion; spinalization; rabbit; lamprey;

    Sammanfattning : Different species maintain a basic body posture due to the activity of the postural control system. An efficient control of the body orientation, as well as the body configuration, is important for standing and during locomotion. LÄS MER
