Summary Introduction

Introduction: The human body’s sensory structures gather information and pass it on to the central nervous system (CNS). The sensory organs are in pairs such as two eyes and two ears. Action potentials from sensory receptors travel along the neurons. These neurons form synapses in the brain or spinal cord. As a result, the brain recognise stimuli, such as sight and sound along with the action potentials have arrived.

Proposed hypothesis: The eye change to aid our vision in different situation with left eye open, right eye open, and both eyes open.
