Case 1 was the fastest with a 0.43 average. Itโs the fastest reaction because it only goes from your sensory neurons in your eyes to your inter neurons to your motor neurons.
The slowest reaction time was Case 4. This is because the signal/inpulse has to travel from the sensory neurons in your orbital region to your frontal cortex where you read it and then negate it and finally to your motor neurons where they tell your muscles to contract or not.
