  1. 1. Dynamics of descending inhibition and neuroendocrine analgesia with special reference to the trigeminal region

    Author : Anna Feldreich; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : In patients with pain, it is of relevance to use clinical assessments that evaluate the pain modulation. In this thesis, the dynamics of descending inhibition or central sensitization and neuroendocrine analgesia were investigated: in healthy volunteers; in patients with chronic closed lock of the temporomandibular joint (TMJ), before and after discectomy; and finally in patients with possible neuropathic pain, (atypical odontalgia).

  2. 2. Neural mechanisms for the control of posture, locomotion and steering : a behavioral, electrophysiological and modeling study in lamprey

    Author : Patriq Fagerstedt; Karolinska Institutet; Karolinska Institutet; []
    Keywords : reticulospinal; vestibular system; spinal cord; central pattern generator; reciprocal inhibition; fictive locomotion; fictive turning; electron microscopy; computer simulation; lamprey; dorsal fin;

    Abstract : When animals move around interacting with the environment, the nervous system has to solve several tasks simultaneously in order to produce and control the movements - notably propulsion, posture, balance, and associated movements. Basic motor tasks are controlled by neuronal networks organized into central pattern generators (CPGs) and reflexes, located in the spinal cord and brainstem. READ MORE

  3. 3. Brain mechanisms in pain regulation

    Author : Karin B Jensen; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The subjective sensitivity to pain differs greatly between individuals and neuroimaging has contributed to the understanding of the cerebral mechanisms involved in pain regulation. The descending pain inhibitory circuitry is a well defined cerebral network that enables regulation of afferent nociceptive information. READ MORE

  4. 4. Hypothalamic and cortical control of jaw reflexes

    Author : Kurt Å. Olsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cat; Oral projections; Cerebral cortex; Cytoarchitecture; Hypothalamus; Defence-Attack area; Jaw reflexes; Bruxism; Myofascial pain dysfunction;

    Abstract : The subject of the thesis is a study of the projections from low threshold oral and face afferents to the cerebral cortex and of descending motor control mechanisms originating in the cerebral cortex or the hypothalamus and influencing the jaw reflexes.Cats anaesthetized with chi oral ose were used for the experiments.

  5. 5. Locomotor pattern generation in the spinal cord : studies in adult lamprey and zebrafish

    Author : Riyadh Mahmood; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : The overall objective of this thesis is to characterize the mechanisms involved in the generation of locomotor activity in the spinal cord. To this end, we initially used the lamprey spinal cord to determine the transmitter phenotype of commissural interneurons (CINs). READ MORE
