  1. 1. Information Processing in the Nervous System. On a Holistic Functional Organization Principle

    Författare :Jonas Enander; Hjärnans sensorimotoriska funktioner; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Somatosensory; Tactile; Neuron; Neocortex; Brain organization; Cortical functional localization;

    Sammanfattning : This thesis is concerned with the nature of information processing in the nervous system. This issue has been investigated with animal experiments, using male Sprague–Dawley rats, and simulated touch generated by an artificial fingertip with neuromorphic tactile sensors. LÄS MER

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

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

    Sammanfattning : 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. LÄS MER

  4. 3. Somatostatin neurotransmission : studies on experimentally induced cognitive changes and Alzheimer’s disease

    Författare :Lars Nilsson; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Alzheimer s disease Adenylyl cyclase Autoradiography Behavior Cerebral cortex DemenbaEnvironment Ibotenic acid lesion In-situ hybridization Learning Neuropeptides Northern blot Nucleus basalismagnocellularis Posttranslational processing Rat Recepto;

    Sammanfattning : Several neuropeptides are widely distributed in regions of the central nervous system (CNS) which are associated with cognitive functions. Multiple studies on postmortem Alzheimer's disease (AD) brains have shown depleted neuropeptide content and morphological abnormalities of somatostatin (SS)-containing interneurons in the hippocampus and the cerebral cortex.

  5. 4. Brain processing of experimental muscle pain and its interrelation with proprioception and muscle fatigue : positron emission tomography study

    Författare :Alexander Korotkov; Docent Tomas Graven-Nielsen; Umeå universitet; []
    Nyckelord :Experimental muscle pain; Hypertonic saline; Kinesthesia; Proprioception; Movement; Vibration; Muscle fatigue; Brain; Imaging; Positron emission tomography; Regional cerebral blood flow;

    Sammanfattning : Chronic muscle pain is a significant medical and social problem and better understanding of the pathophysiological mechanisms involved is an important requirement for further development of diagnostics, treatment and rehabilitation methods. Experimental imaging studies have investigated functional neuroanatomy of different pain components. LÄS MER

  7. 5. Visual evoked potentials in the horse

    Författare :Lena Ström; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES;

    Sammanfattning : Vision is an important sense for horses, both for survival in the wild and when horses are used for work, sport or recreation. However, it is often difficult to diagnose visual impairment in this species. LÄS MER
