The long-term goal of Dr. Kojima's lab is to understand neural mechanisms of eye movement learning and treat abnormal eye movements. In particular, her lab focuses on saccade, a fast eye movement to direct line of sight to an object of interest. The lab uses behavioral tests, neurophysiological recording, micro electrical stimulation, pharmacological manipulation, and optogenetics to investigate how the brain creates and adjusts the saccade signal with integrating sensory inputs, such as, vision, memory, and rotation of the head.
