The effects of alcohol hit your brain like a tidal wave. You can
go from jovial, to falling-down drunk, to dead and it doesn't
take very long to get there. Watch this video to witness the
effects of severe intoxication: Firstly it suppresses the
frontal lobes, then it goes to the back of your brain, and then
to the parts deep in the centre. Dr Izak Loftus, forensic and
anatomical pathologist explains: Alcohol is a suppressant as it
suppresses the normal functions of your brain. This suppressing
effect on the brain is almost like a wave crashing over your
head. First it suppresses the frontal lobes, then it washes
further backwards over the parietal lobes, then to the parietal
lobes, the occipital lobes right at the back, then deeper into
the brain to the cerebellum and lastly to the diencephalon and
the mesencephalon (midbrain), and then down to the brainstem and
the medulla oblongata. This process is continuous, but certain
functions, for example peripheral vision, may already be
affected at an earlier stage
