1. Programming and updaing of reaching movements
Sammanfattning : Neuronal activity in the motor cortex (area 4) was recorded during reaching movements in cats, trained to perform target-reaching in response to a tone burst. Out of 350 task related neurones 12% generated short latency (20?110 ms) sensory responses to the cue triggering the reaching movement. LÄS MER
2. Correlations of Higher Order in Networks of Spiking Neurons
Sammanfattning : The topic of this dissertation is the study of the emergence of higher-order correlations in recurrentlyconnected populations of brain cells.Neurons have been experimentally shown to form vast networks in the brain. LÄS MER
3. Short- and long-term neuronal plasticity in hippocampal CA1 region of rat
Sammanfattning : The brain is highly plastic, displaying both short- and long-term changes, resulting from developmental processes as well as learning and memory. Moreover, short-term plasticity such as paired pulse facilitation and depression (PPF, PPD) have long been used to monitor the presynaptic versus postsynaptic changes occurring during more lasting processes such as long-term potentiation and depression (LTP, LTD).

4. Dissecting the intrastriatal neuronal circuitry that regulates direct and indirect striatal projections
Sammanfattning : The basal ganglia (BG) are a group of subcortical nuclei that are interconnected in multiple parallel cortico-BG-thalamocortical loops. They have been implicated in many functions, among them action control and motor learning. The striatum forms the main input nucleus of the BG. LÄS MER
5. Towards a Translational Pain Model - Techniques and developments
Sammanfattning : Pain is a major health issue for each affected individual and has a large impact on health costs. Most of our knowledge about this defensive system rely on data from different animal experiments. There is an obvious need for a translational pain model allowing comparisons between experimental animals and humans. LÄS MER
