Final answer:

The brain is most active during REM sleep, primarily towards the end of each sleep cycle.


Explanation:

The brain is most active during REM sleep (Rapid Eye Movement), which occurs mostly towards the end of each sleep cycle. During REM sleep, the brainwaves resemble wakeful brain activity, and this stage is where dreaming primarily occurs. As the night progresses, the length of REM sleep increases, leading to more vivid dreams.
