1.5

Minimum number of milliseconds it takes for the human body to register a taste. According to Dr. Hildegarde Heymann, at the University of California at Davis, taste perception is swift because the tongue and mouth (assisted by the nose) are the body’s primary defenses against poison. For our four main senses: taste takes: 1.5 to 4.0 milliseconds, touch: 2.4 to 8.9 milliseconds, hearing: 13 to 22 milliseconds, and vision: 13 to 45 milliseconds.
