BMI effect with different ejecting currents on stimulus-size tuning. Although the response to the CRF stimulation markedly increased depending on current intensity, the surround suppression did not significantly decrease. BMI administration with ejecting currents of 5 and 9-12 nA increased the response to the CRF grating up to 260 and 445%. SI values were 0.96 (Control), 0.95 (BMI; 5 nA), and 0.87 (BMI; 9-12 nA), and the reductions in the surround suppression, calculated using (Control SI - BMI SI)/Control SI, were 0.4% (BMI; 5 nA) and 8.8% (BMI; 9-12 nA).
