Basic Research
What medication can make you use your brain 100 percent?
You already use 100% of your brain. It is a myth that we don't. See related question, "Why can't people use 100% of their brains ?" Also related link.

The above answer refers to convulsions, not convolutions! Brain convolutions are the wrinkles on its surface.
What does the medulla controls?
The Medulla controls the body functions such as breathing, digestion, blood flow and body temperature.
If you didn't have a brain, you really couldn't do anything pretty much. Example: You wouldn't be able to walk, because you would forget how to walk. Why we have a brain? We have a brain so we can think, ( or walk. :-} ) If you didn't have a brain you wouldn't be able to ask this question.
Actually walking is controlled almost entirely by nerve paths in the spine, the brain is not involved except to select where we are walking to (part of thinking).
What is the function of the limbic system?
The limbic system controls the sense of smell (olfaction), emotion, behavior, and long-term memory.
How do you take out brain warp batteries?
The toy has six knobs, the batteries are stored under the yellow know (No.6)
If you look closely, you will see a phillips screw n the center, just remove it and the lid will pop off, exposing the batteries so you can install new ones.
Which carnial nerves are purely sensory?
Actually, there are three cranial nerves that are completely sensory: Olfactory nerve, Optic nerve and the Vestibulocohlear nerve. The Optic nerve is responsible for sensory information for vision, the Olfactory nerve is responsible for sensory information coming from the nose and the Vestibulocohlear (the craziest word to spell) involves sensory information for hearing (get it?- cohlear, ear) and equilibrium.
How do inhibitors affect the brain?
If you're talking about SSRI's, they are "selective serotonin reuptake inhibitors". In the case of depression, your body absorbs the serotonin that you make to scavenge the molecules to make... serotonin. SSRI's stop your body from scavenging the serotonin to get the molecules. SSRI's inhibit the body from "reuptaking" the serotonin. SSRI's are the most natural treatment of depression, since they do not attempt to create an alternative to serotonin, there are minimum side effects. But there are occasionally some side effects, depending on the SSRI that is used.
What causes diminished hearing and a throbbing sound in only my left ear which sometimes stops?
This is referred to as pulsatile tinnitus.
I want to give you an overview of the different kinds of problems that can cause pulsatile tinnitus (tinnitus which throbs at the same rate as your heart beat. I assume you have already determined whether this is, in fact, the case, by feeling your pulse and listening to the tinnitus at the same time).
Here's a partial list, hitting the high points:
Vascular disorders (high blood pressure; abnormal placement of vessels within the middle ear; blood vessels which are abnormally narrow; aneurysms; arteriovenous malformations).
Tumors in or near the ear that are highly vascular.
Middle ear inflammation due to acute or chronic infection, or Eustachian tube dysfunction.
The noise will be repetitive but will NOT coincide with your heartbeat, if your problem is myoclonus.
The big worry, obviously, is that the pulsatile tinnitus is related to a vascular disorder or highly vascular tumor. If you see an ENT, he/she will know how to examine you with this in mind and will know the appropriate tests that need to be done to figure this out.
THE NERVOUS SYSTEM
The Central Nervous System-the brain and spinal cord
1. Cerebrum-memory, thinking, learning, controls movement, senses report info here.
2. Cerebellum- 2nd largest, controls balance and coordination
3. Brain stem- controls breathing, digestion, heart rate, and blood pressure/connects brain to spinal cord
The spinal cord connects various organs of human body to the brain
Sensory neurons take signals from senses and brings messages to the Central Nervous System
Motor neurons carries out brains instructions (pull away from pain)
Interneurons takes info from sensory neuron (pain) sends it to brain
The Eye
The lens bends and focuses light rays
The retina is the screen of the eye, light is changed to electricity
The iris controls amount of light entering the eye
The optic nerve carries electrical impulses to the brain
The pupil light enters the eye through this hole
The cornea thin, transparent protective membrane
The choroid contains blood vessels that nourish the eye
The aqueous humor watery fluid in front of the eye
The vitreous humor jelly like fluid, keeps shape of back of eye
The sclera opaque, tough protective membrane
The Human Ear Table
Hammer amplifies sound first
Anvil amplifies sound second
Semi-circular canals controls sense of balance
Auditory nerve carries electrical impulses to the brain
Cochlea changes sound waves into electricity
Stirrup amplifies sound third and last
Ear drum vibrates with incoming sound waves
Eustachian Tube equalizes air pressure
Auditory canal passageways for vibrations
Pinna catches and funnels vibrations
I hope this helped. Each section has something to do with the brain so take some time to read it all. :)
Edit: AMAZING answer - nicely COPIED & PASTED from a web-site !
