In this paper, brain-machine interface (BMI) was adopted to investigate the motor area in the animal brain. Stainless steel wire electrodes were implanted to search the brain area for rotation, forward movement, and flapping. In continuation of our search for optimized coordinates for stimulation, we designed electrode case for safer transport and for a more accurate fabrication of the electrode array. The cases are customized for each set of coordinates, and quickly built using a 3D printer. The case reduced the surgery time and increased accuracy in electrode placement. Stimulation of various sites in the brain derived the pigeon to move as we have anticipated.
