Motor control in brain and spinal cord
We are interested in understanding how the electrical activity among populations of neurons self-organizes to produce behaviors. Our model system is motor pattern generation in the spinal cord of limbed terrestrial vertebrates.
During motor behaviors there is an intense communication between neurons responsible for the generation. This is for instance manifested in the fluctuations in membrane potential of neurons during network activity. In the spectrogram figure is shown a sample trace of the spectral content of a motoneuron during a motor task, illustrating the intense synaptic bombardment following onset. We are particularly interested in how the slow motor rhythms emerge out of such fast and stochastic activity.
