Siavash joined the lab as a MS BME student in 2004.  He worked on saccadic remapping of reach target.  He made an important observation: the brain combines predicted sensory consequences of motor commands with actual sensory feedback to produce an estimate that is better than either source of information.  That is, as the brain predicts consequences of movements, it acquires the ability to sense the world better than is possible from the sensors alone.  He demonstrated that we see the world better than what our eyes tell us because we can predict what we should see.  After completing his MS, he joined the PhD program in BME at Johns Hopkins, working in the area of cortical neurophysiology.  Following completion of PhD, Siavash accepted a position as Scientific Research Analyst at NIH.

 

His results were published in the following works:
