To begin, let's restate the question and the available choices to set the context.
Question: In this stage of sleep, we are no longer responsive to the outside world and our sensory experiences drop.
Answer options: 3, 4, 1, 2

Option 3: This would refer to Stage 3 sleep in some schemes (or Stage 3 of deep non-REM sleep before Stage 4 was distinguished). However, in classic staging a deeper cutoff exists between Stage 3 and Stage 4, with Stage 3 not always characterized by the complete unresponsiveness and maximal sensory reduction described. Therefore this option does not accurately capture the statement that we are no longer responsive to the outside world and have a drop in sensory experiences to the greatest extent.

Option 4: This is the intended correct option. Stage 4 sleep (sometimes labeled N4 or NREM 4) represents the deepest non-REM sleep in many classifications, during which arousal thresholds are highest and responsiveness to external stimuli is markedly reduced; sensory input is largely disengaged, and sleep is profoundly restorative. The description aligns with the classic characterization of deepest sleep when the outside world has minimal influence.

Option 1: Stage 1 sleep is the lightest sleep, occurring as you drift from wakefulness to sleep. During this stage, responsiveness to stimuli is still present, and sleep is easily interrupted. The statement about no longer being responsive and a big drop in sensory experiences does not fit Stage 1, so this option is incorrect.

Option 2: Stage 2 sleep is a light to moderate non-REM stage featuring features like sleep spindles and K-complexes. While responsiveness to the environment decreases compared to wakefulness, it is not the stage typically described as where we are no longer responsive and where sensory input is dramatically reduced to the greatest extent. This makes option 2 also incorrect.

In summary, option 4 is the best match for the description of being unresponsive to the outside world with a pronounced drop in sensory experiences, while options 3, 1, and 2 correspond to lighter or intermediate stages where some responsiveness and sensory processing can still occur.

In this stage of sleep, we are no longer responsive to the outside world and our sensory experiences drop.

When our brain waves are in the waves activity, one would be in stage one of sleep.

When we enter this stage of sleep, our brain waves change to theta waves.

Each stage of sleep is characterized by different types of brain wave patterns.
