Number of neurons related to eye movements in the scanning eye movement task.

EM-related neurons – the number of eye movement-related neurons associated with at least one kinematic parameter (†Bonferroni-corrected number of neurons for three kinematic parameters). Neurons functionally associated with one or more kinematic parameters (POS – eye position; VELOC – eye velocity; ACCEL – eye acceleration) are reported for each nucleus separately (STN – subthalamic nucleus; GP – globus pallidus; SNr – substantia nigra pars reticulata). Number of neurons significantly greater than expected 5% false positivity rate is denoted: *(p<0.05), **(p<0.01) ***(p<0.001).
