  2. 16. Measuring the tactile sense: Cortical mechanisms and clinical applications of tactile direction discrimination

    Author : Linda Lundblad; Göteborgs universitet; []
    Keywords : AIC; diabetic neuropathy; DLPFC; fMRI; hairy skin; psychophysics; QST testing; somatosensory cortex; tactile direction discrimination;

    Abstract : Most of the studies aiming to investigate the human tactile sense are done on the glabrous skin. Still, there is a need for a quantitative method for evaluating nervous function of the hairy skin. READ MORE

  4. 17. Structural and functional changes in the brain after surgically repaired median nerve injury

    Author : Per F. Nordmark; Roland S. Johansson; Henrik Ehrsson; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Humans; Hand; Touch; Peripheral nerve injury; Magnetic resonance imaging; Somatosensory Cortex; Cortical plasticity; fysiologi; Physiology; handkirurgi; hand surgery;

    Abstract : Despite the best available surgical repair, traumatic median nerve injury within the forearm typically causes lifelong impairment in hand function. This stems from an inadequate reinnervation of the nerves supporting sensory functions of the thumb, index and long finger, and of nerves supplying intrinsic hand muscles. READ MORE

  5. 18. Beyond AMPA and NMDA: Slow synaptic mGlu/TRPC currents : Implications for dendritic integration

    Author : Marcus Petersson; Erik Fransén; Abdel El Manira; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; transient receptor potential; TRP; metabotropic glutamate receptor; mGlu1 5; dendritic integration; synaptic activation; temporal summation; low-frequency; entorhinal cortex; mathematical model; computational neuroscience; Computer science; Datavetenskap;

    Abstract : In order to understand how the brain functions, under normal as well as pathological conditions, it is important to study the mechanisms underlying information integration. Depending on the nature of an input arriving at a synapse, different strategies may be used by the neuron to integrate and respond to the input. READ MORE

  6. 19. To select one hand while using both : neural mechanisms supporting flexible hand dominance in bimanual object manipulation

    Author : Anna Theorin; Roland Johansson; Fredrik Ullén; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; object manipulation; bimanual coordination; action selection; cerebral cortex; functional laterality; humans; hand; magnetic resonance imaging; transcranial magnetic stimulation; electromyography; Physiology; Fysiologi; fysiologi; Physiology;

    Abstract : In daily activities, the brain regularly assigns different roles to the hands dependingon task and context. Yet, little is known about the underlying neural processes. Thiscertainly applies to how the brain, where each hemisphere primarily controls onehand, manages the between-hand coordination required in bimanual objectmanipulation. READ MORE

  7. 20. 5-HT receptor-mediated modulation of glutamate transmission in the hippocampus and prefrontal cortex and its relation to cognition and depression

    Author : Tiberiu Loredan Stan; Karolinska Institutet; Karolinska Institutet; []
    Keywords : ;

    Abstract : Depression is a multifaceted disease which is marked by cognitive and emotional memory impairments. It is characterised by an imbalacement of serotonergic and glutamatergic system in brain areas such as hippocampus and prefontal cortex. READ MORE
