Research Statement:

I investigated self-sustain oscillation related to the brain memory and procedure of memory based on different mathematical neuronal models and synapse models during my Ph.D time. The results showed that self-sustain patterns which may be correlated with dream were generated by only changing one neural network link or network connection without any external stimulus and procedure of memory from the short-term memory to long-term memory was accomplished based on heterogeneous synapse connection of neural networks. I also studied the synchronization in a two-dimensional Hindmarsh-Rose neuronal network by introducing a global coupling scheme with time delay, where the length of time delay is proportional to the spatial distance between neurons.
Currently, I am studying, in collaboration with Patricio Orio at CINV, the chaos with single neural model and neural networks stuff.
