  1. 1. Nervous mechanisms of postural control

    Author : Anastasia Karayannidou; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Postural control; equilibrium; body confguration; motor cortex; reticulospinal system; standing; locomotion; spinal cord injury; cat; rabbit; lamprey;

    Abstract : Maintenance of body confguration and orientation in space (postural control) is a vital motor function. A general goal of the present study was to analyze nervous feedback mechanisms for the maintenance of posture during different motor behaviors and with different postural perturbations. READ MORE

  2. 2. Computer Simulation of the Neural Control of Locomotion in the Cat

    Author : Nalin Harischandra; Örjan Ekeberg; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Locomotion; Computer simulation; Central pattern generator; Muscle activation; Linear transfer functions; Sensory feedback; Neural control; Computer science; Datavetenskap;

    Abstract : Locomotion is one of the most important behaviours and requires interaction between sensors at various levels of the nervous system and the limb muscles of an animal. The basic neural rhythm for locomotion in mammals has been shown to arise from local neural networks residing in the spinal cord and these networks are known as central pattern generators (CPGs).

  3. 3. Vestibular control of body orientation in lamprey

    Author : Elena Pavlova; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Postural control; orientation; vision; vestibular system; visuo-vestibular interaction; vestibular compensation; locomotion; supraspinal control; lamprey;

    Abstract : Maintenance of body orientation (postural control) is a vital motor function of the brain. The general goal of this project was to understand the organization and operation of neuronal networks responsible for postural control. The lamprey (a lower vertebrate) was used as a model animal.

  4. 4. Neuronal mechanisms of feedback postural control

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

    Abstract : 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. READ MORE

  5. 5. Central nervous system targets for micturition control

    Author : Rikard Pehrson; Avdelningen för klinisk kemi och farmakologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; central nervous system; Micturition; 5-HT; GABA; tramadol; NAD-299; CGP62349; apomorphine; cerebral infarction; toxikologi; farmaci; farmakognosi; Farmakologi; toxicology; pharmacy; pharmacognosy; Pharmacological sciences;

    Abstract : Normal urine storage and bladder emptying are controlled by the central (CNS) as well as the peripheral nervous system. Dysfunction of these mechanisms can lead to urinary incontinence. Urinary tract dysfunctions have symptomatically been treated mainly with drugs acting peripherally. READ MORE
