1. Itch and Pain Inhibitory Mechanisms in Humans - evidence for a differential control of nociceptive senses
Abstract : It is known that stimulation of thin nerve afferents can inhibit itch and pain and that the nociceptive systems have a detailed topographical organisation, with subsystems exhibiting specific excitatory and inhibitory receptive fields. On this basis, a new technique was developed, termed Cutaneous Field Stimulation (CFS), that electrically stimulates thin nerve fibers innervating specific skin fields. READ MORE

2. The functional organisation of basal ganglia inputs
Abstract : The basal ganglia allow organisms to adjust their behaviour according to changes in their internal state or their environment. One essential prerequisite for the selection and execution of appropriate movements is the convergence of inputs from various sources, conveying sensory information, motor commands, reward value, and more.

3. On mapping the human somatosensory cortex : fMRI and PET imaging
Abstract : This work is based on experiments and simulations for the purpose of mapping the human somatosensory cortex. By using a combination of structural mapping (cytoarchitecture), connectivity mapping, functional mapping, and somatotopical mapping an overview of the organisation of the human somatosensory cortex at different levels is possible.

4. New functional and anatomical aspects of the organisation of human peripheral nerve
Abstract : The functional topography of peripheral nerves has been studied by various indirect electrophysiological and histological methods. Even though some studies have suggested the presence of a somatotopical arrangement of nerve fibres, the prevailing view is that a random distribution of nerve fibres develops in the nerve due to the repeated rearrangement of nerve fascicles along their centripetal course.

5. Functional mapping of somatosensory cortices in the human brain
Abstract : Tactile perception is a remarkable ability that enables us to recognise objects and handle tools. Cortical processing during tactile and shape perception in humans is not fully understood. READ MORE
