    Abstract : It is known that some psychiatric disorders may deteriorate in relation to the menstrual cycle. However, in some conditions, such as premenstrual dysphoric disorder (PMDD), symptomatology is triggered mainly by the variations in ovarian steroid hormones. READ MORE

  4. 2. Thin-fibre signalling in humans: Cortical processing of sensory afference and autonomic efference

    Author : Karin Rylander; Göteborgs universitet; []
    Keywords : CT afferent; thin fibre; autonomic; insula; fMRI;

    Abstract : Thin nerve fibres innervate the entire human body and mediate sensations such as pain, temperature and visceral sensory input. Moreover, a special class of unmyelinated afferents responsive to light touch has recently been found in humans: C-tactile (CT) fibres. READ MORE

  5. 3. Prior knowledge and present events in the brain

    Author : Katrina Carlsson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Anticipation; prediction; predictability; attention; emotion; pain; tickle; fear; conscious; unconscious; awareness; amygdala; insula; functional magnetic resonance imaging fMRI ; positron emission tomography PET ;

    Abstract : Our experience the world is dependent on both the surroundings and the brain. In other words, perception is a synthesis of incoming signals, internal state, and previous knowledge rather than a mere reflection of the environment. READ MORE

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

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

    Abstract : 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. READ MORE

  7. 5. From social drinking to alcohol addiction : Decision making and its neural substrates along a spectrum from social drinking to alcohol addiction

    Author : Hanna Karlsson; Irene Perini; Markus Heilig; Bo Söderpalm; Linköpings universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; alcohol; heavy drinking; alcohol addiction; decision making; alcohol choice; fMRI; rTMS;

    Abstract : For a minority of alcohol users, the initial sip of alcohol marks the start of a life-threatening process. This thesis studies cognitive mechanisms pertinent to alcohol addiction and its development, using a spectrum of individuals that range from healthy social drinkers, through people with hazardous use, to those suffering from alcohol addiction.
