Outline of Final Research Achievements

The present research 1) revealed that the taste stimuli of sour and bitter solutions in high concentrations increased the number of eye blinks, and shortened the latency and prolonged the duration of the first eye blink, but 2) did not find significant differences in the three eye-blink responses between seven test foods used (i.e., commercial confectioneries), and 3) developed a stimulation-recording system for the gusto-eye blink responses that does not require clamping of the head and tongue using a tasimetric sensor.
