  1. 1. Negative symptoms, repetitive transcranial magnetic stimulation and heart rate variability in schizophrenia and depression

    Författare :Johan Bengtsson; Robert Bodén; Jonas Persson; Erik Olsson; Caroline Wass; Jimmi Nielsen; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; negative symptoms; psychotic disorders; affective disorders; non-invasive brain stimulation; transdiagnostics; psychometrics; autonomic nervous system; Psychiatry; Psykiatri;

    Sammanfattning : Negative symptoms comprise anhedonia, avolition, and blunted affect. Although first described in schizophrenia, these symptoms share phenomenology with the depressive state. Pharmacological treatment has not been successful in reducing negative symptoms. LÄS MER

  2. 2. Brain functional near infrared spectroscopy in human infants : cerebral cortical haemodynamics coupled to neuronal activation in response to sensory stimulation

    Författare :Marco Bartocci; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :Near infrared spectroscopy; newborn; infant; brain; sensory stimulation; cortical activation;

    Sammanfattning : The assessment of cortical activation in the neonatal brain is crucial in the study of brain development, as it provides precious information for how the newborn infant processes external or internal stimuli. Thus far functional studies of neonates aimed to assess cortical responses to certain external stimuli are very few, due to the lack of suitable techniques to monitor brain activity of the newborn.

  3. 3. Cortical plasticity in response to median nerve trauma

    Författare :Lotta Fornander; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Median nerve injuries in adults, repaired with nerve suture, lead to incomplete functional recovery despite improved surgical technique. This results in a reduction in quality of life, poorer working ability and a considerable expense for society. Misrouting of axons at the suture site connects regenerating axons to the wrong distal end organs. LÄS MER

  4. 4. Physiological and pathophysiological cerebrovascular regulation monitored by transcranial doppler

    Författare :Gunnar Hellström; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Transcranial Doppler ultrasonography (TCD) became available in the middle of the 1980s as a new technique for examining cerebral circulation. With this technique it is possible to measure the velocity of blood flow in major cerebral arteries. LÄS MER

  5. 5. Mathematical Modelling of Cerebral Metabolism : From Ion Channels to Metabolic Fluxes

    Författare :Nicolas Sundqvist; Gunnar Cedersund; Maria Engström; Roland Nilsson; Sebastian Sten; João Duarte; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The brain is the most metabolically active organ in the human body and therefore rely on a continuous supply of oxygen and glucose. Neuronal stimulation in specific regions of the leads to the firing of action potentials, a process facilitated by voltage-gated ion channels in the neurons’ cell membranes. LÄS MER
