It was said in the video that when a person is drunk, the alcohol affects only the cerebellum and hence he cannot stand or move properly. But is a drunk state the paerson doesnot even talk properly or talk sense then how can alcohol affect only the  cerebellum that only controlls our movements?? Please answer this question as soon as possible  

Alcohol affects different regions of the brain in different ways:

Cerebral cortex: Alcohol slows down the processing of information from eyes, ears, mouth and other senses. It does not allow a person to think clearly.

Cerebellum: Alcohol affects this centre of movement and balance, resulting in staggering and loss in body balance.

Hypothalamus and pituitary: The hypothalamus and pituitary coordinate automatic brain functions and hormone release. Alcohol depresses nerve centres in the hypothalamus and cause imbalance in hormonal secretion.

Medulla: Medulla controls functions such as breathing, consciousness and body temperature. Alcohol induces sleepiness and can also slow down breathing and lower body temperature, which can be life-threatening.
