Abstract
The plasticity of the nervous system during the processing of sensory information is of major interest to interdisciplinary neurobiology research. Here, we used an insect model system with stereotyped behavioral patterns for the investigation of how the nervous system can switch between two different motor outputs, walking and standing, despite having the same sensory input, in a computer simulation based on the known network structure. The strengths of 16 specific information pathways which integrate sensory information were permutated and the resulting database of more than 43 million network outputs was analyzed. Two independent analysis show that the same neural network can produce two different behaviors by specifically altering the weighting of several information pathways. We obtained specific combinations of pathway transmission levels that produced these behaviors. This means, that solely changing the strength with which a pathway transmits sensory information is sufficient to switch between .different behaviors, like from standing to walking. The predictions that derive from our results can now be used in physiological experiments.
