Final answer:
The question involves the medical assessment of consciousness where a patient's response to commands (opening/closing eyes but not gripping/releasing hand) indicates brain function. An associated example involves focusing on a finger and noting the shift in position when alternating closed eyes, demonstrating the parallax effect.
Step-by-step explanation:
When the question references '1c LOC commands' it is likely addressing the Level of Consciousness (LOC) in a medical context, particularly as part of a neurological assessment. The LOC scale is used to determine a patient's state of awareness and responsiveness to stimuli. When an individual follows a command to open and close eyes but does not grip or release a hand upon request, the healthcare provider can draw conclusions about brain function and potential impairment. For a simple at-home demonstration of the response of the senses, one can perform the following exercise:
Hold out a single finger in front of you and maintain your focus on that finger. Now, close your left eye without moving your head, then open your left eye and close your right eye without moving your head. You will notice that your finger seems to shift when you switch visual dominance from one eye to the other. This occurs due to the different perspectives each eye has, creating a phenomenon known as 'parallax'.
