Which Part Of The Brain Deals With Emotions
Now, you know what parts of the brain deal with thinking and memory. Lets have a quick look at the part that is responsible for emotions.
All positive and negative emotions, and spontaneous feelings think excitement and sadness, are being processed in the limbic system.
The limbic system control your emotions and interacts with other parts of the brain.
In the same time, another part of the brain called amygdala handles emotional reactions such as love, hate, and sexual desire.
With centuries of research, the human brain remains the biggest mystery in the world. It is the most complex part of the body that controls movement, sight, and thinking.
How Does My Body Keep Its Balance
Your sense of balance relies on a series of signals to your brain from several organs and structures in your body, specifically your eyes, ears, and the muscles and touch sensors in your legs. The part of the ear that assists in balance is known as the vestibular system, or the labyrinth, a maze-like structure in your inner ear made of bone and soft tissue.
Structures of the balance system inside the inner ear
Within the labyrinth are structures known as semicircular canals. The semicircular canals contain three fluid-filled ducts, which form loops arranged roughly at right angles to one another. They tell your brain when your head rotates. Inside each canal is a gelatin-like structure called the cupula , stretched like a thick sail that blocks off one end of each canal. The cupula sits on a cluster of sensory hair cells. Each hair cell has tiny, thin extensions called stereocilia that protrude into the cupula.
When you turn your head, fluid inside the semicircular canals moves, causing the cupulae to flex or billow like sails in the wind, which in turn bends the stereocilia. This bending creates a nerve signal that is sent to your brain to tell it which way your head has turned.
The Basics Of The Vestibular System
Think of the vestibular system as a messenger service. Located in the inner ear, the vestibular system provides your brain with information on things like motion, the position of your head, and sudden movements. This helps you maintain your balance by ensuring that your brain processes your bodys position every time it changes. Overall, the vestibular system helps you maintain a sense of equilibrium, preventing falls and dizziness.

S Of The Brain Alcohol Affects
What is the Frist Brain Function Affected by Alcohol?
The first area compromised is the Cerebral Cortex, which causes confusion and lowers inhibitions. For example, jokes start to seem funnier, and a user may be less afraid to talk to new people or do something else that is out of their comfort zone. Next, it hits the cerebellum, altering movement and balance. This is why people who are intoxicated may be more likely to fall or have slurred speech.
If the user continues to drink, the hypothalamus and amygdala become affected. This may make it harder to control emotions, and some people may even injure themselves and not realize it until the next day. At this point of consumption, the user can be described as someone who is acting on animal instincts, since all parts of the brain that regulate human reasoning have gone offline.
If a user continues to drink at this point, it may affect the brain stem, which induces sleep and can cause irregular breathing and even seizures. This is how even one binge event can lead to an untimely death. Fortunately, most stop drinking or pass out before this level of impairment.
What Is A Balance Disorder
A balance disorder is a condition that makes you feel unsteady or dizzy. If you are standing, sitting, or lying down, you might feel as if you are moving, spinning, or floating. If you are walking, you might suddenly feel as if you are tipping over.
Everyone has a dizzy spell now and then, but the term dizziness can mean different things to different people. For one person, dizziness might mean a fleeting feeling of faintness, while for another it could be an intense sensation of spinning that lasts a long time.
About 15 percent of American adults had a balance or dizziness problem in 2008. Balance disorders can be caused by certain health conditions, medications, or a problem in the inner ear or the brain. A balance disorder can profoundly affect daily activities and cause psychological and emotional hardship.

How Does Alcohol Work In The Brain
When a person ingests alcohol, it quickly enters the bloodstream, through the bloodstream, it enters the brain. In the brain, alcohol affects neurotransmitters, which are chemical messengers that either increase or decrease brain activity through electrical impulses. Alcohol addiction, unlike addictions to many other drugs, affects many different neurotransmitters at the same time, demonstrating why recovery can be so difficult for someone with Alcohol Use Disorder.
With regards to why many people associate alcohol with becoming more social, Gamma-aminobutyric acid is the answer. GABA helps rid the user of inhibitions and slows down the brain. Dopamine, Glutamate, and Serotonin stimulate pleasure and activate the brainâs reward center, giving it the signal that alcohol, like food, is good for your well-being. But serotonin and glutamate levels drop the more you drink, and as you consume more it can leave you feeling depressed.
What Part Of Your Body Controls Balance
The eyes, the joints and muscles and the vestibular organs in the inner ears control a bodys balance by sending nerve signals to the brain. Dysfunction in any one of these systems can result in loss of balance.
Light-sensitive nerve endings, or sensory receptors, in the retina send nerve impulses to the brain. These visual sensory signals are used by the brain to help maintain balance.
Sensory input provided by muscles and joints, the sense of proprioception, is received by the brain. The muscles and joints are surrounded by sensory receptors sensitive to pressure or stretch, and these sensory impulses tell the brain what the body is doing at any instant. The impulses that come from the neck, which indicate the heads direction, and the impulses that come from the ankles, which determine the bodys movement or sway, are the most important.

S Of The Brain: Structures Anatomy And Functions
The human brain is one of the largest and most complex organs in the body. It controls your emotions, thoughts, speech, memory, creativity, breathes, movement, and stores information from the outside world. This article discusses the different parts of the brain and the function of each structure.
The brain is a 3-pound organ that contains more than 100 billion neurons and many specialized areas. There are 3 main parts of the brain include the cerebrum, cerebellum, and brain stem. The Cerebrum can also be divided into 4 lobes: frontal lobes, parietal lobes, temporal lobes, and occipital lobes. The brain stem consists of three major parts: Midbrain, Pons, and Medulla oblongata. Although each structure has a distinct function, they work together to control all functions of the body.
Treatment For Balance Disorders And Dizziness
Sometimes, balance problems require medical management, such as surgery or medication. You may also benefit from balance treatment called vestibular rehabilitation. Audiologists and other rehabilitation professionals can help improve your balance and reduce dizziness and bothersome symptoms. Vestibular rehabilitation may include exercises with specific movements of the head, eyes, and/or body. Certain types of dizziness may be treated with repositioning procedures. Balance treatment may be provided by an audiologist, a physical therapist, an occupational therapist, or another specialist.

What Controls The Bodys Balance
In addition to the cerebellum, two crucial structures in maintaining balance are the inner ear and the vestibular cranial nerves.
Located in the inner ear, the vestibular system provides your brain with the necessary information for motion, head position, and spatial orientation.
It also plays a role in your motor functions that are involved in keeping your balance, stabilizing your head and body during movement, and also helps maintain your posture.
The vestibular system is absolutely essential for your bodys equilibrium, thus making it a vital part aiding you in balance.
Damage to any part of the brain related to balance isnt inherently life-threatening, however, it can result in jerky and uncoordinated movements if the damage is severe.

Good Balance = Better Brain
Do you wobble if you stand on one foot? How about with your eyes closed? If you walk in a straight heel-to-toe line do you stumble? How about with your eyes closed? If you stand with your feet together and close your eyes do you sway to one side? Do you walk with a wide gait, or feel like youre going to fall if you dont hold the handrail going down the stairs? If you answered yes to any of these questions you have balance issues that could be a sign of compromised brain health and increased risk of dementia later in life.
Balance is governed largely by the cerebellum, the area at the base of the brain that also helps with precision, coordination, and timing of motor movements. The cerebellum is one of the most continually active areas of the brain because not only does it keep you from falling over, it also processes information from gravity.
A healthy cerebellum is important because it constantly feeds a steady stream of information to the entire brain, which is necessary for overall good brain health and function.
This is where problems can occur. When cerebellum function begins to break down, causing such symptoms as worsening balance, this impacts the stream of information going to the rest of the brain. For instance, a healthy cerebellum regulates this stream of information so as not to flood the brain. When the cerebellum degenerates, it can overwhelm the brain with excess input.
Main Brain Parts And Their Functions Explained
The human brain is a complex organ that holds the most importance in the entire human body. The objective of this article is to give you an introduction about the brain parts and their functions rather than a detailed review of the research that has been done on the brain. The brain weighs just 3 pounds but is responsible for controlling behavior, interpreting the senses and initiating body movement. It is the source of intelligence in our body and is located in a bony shell that is protected by brain fluid. The brain is the reason for all of the qualities we possess that make us human beings.

What Does The Brain Do
The brain controls what you think and feel, how you learn and remember, and the way you move and talk. But it also controls things you’re less aware of like the beating of your heart and the digestion of your food.
Think of the brain as a central computer that controls all the body’s functions. The rest of the nervous system is like a network that relays messages back and forth from the brain to different parts of the body. It does this via the spinal cord, which runs from the brain down through the back. It contains threadlike nerves that branch out to every organ and body part.
When a message comes into the brain from anywhere in the body, the brain tells the body how to react. For example, if you touch a hot stove, the nerves in your skin shoot a message of pain to your brain. The brain then sends a message back telling the muscles in your hand to pull away. Luckily, this neurological relay race happens in an instant.
Ataxia Caused By Stroke
Stroke is a clot or bleed in any part of the brain. The cerebellum is a less common site for stroke than the cerebrum, but it can still occur there.
A clot or bleed in the cerebellum can cause the following:
Treating the stroke might resolve the ataxia. Occupational and physical therapy can help manage any permanent damage.

History Of The Cerebellum
The distinct appearance of the cerebellum was first described thousands of years ago by philosophers. The Roman physician Galen gave the earliest written surviving descriptions of this part of the brain.
It was not until the early 19th-century, however, that physicians and researchers began to learn more about the functions of this region of the brain. Experimental work that involved ablating portions of the cerebellum in animals revealed that this part of the brain is important in the coordination of movement.
Basal Ganglia & Thalamus
Findings in the subcortical regions were mainly driven by the basal ganglia and thalamus thus highlighting their importance in balance. The basal ganglia are another known hub of motor function and therefore are highly implicated in balance disorders. Although there was no specific trend of changes within the sub-structures of the basal ganglia, gray matter volume reduction in any part of the basal ganglia structure commonly had negative effects on balance, and volume increases were commonly associated with improved balance .
Similar to the basal ganglia, the thalamus is thought to play a key role in balance as well as several other sensory-motor functions. Its role in motor ability has been documented through lesion studies of thalamic nuclei and correspondence with movement deficits . Deficits specific to balance were also associated with atypical thalamic presentation such as white matter hyperintensities , impaired white matter integrity , and reduced gray matter volume . The critical nature of the thalamus in balance is corroborated by the findings that individuals with expert balance had increased thalamic gray matter volume .

Blood Supply To The Brain
Two sets of blood vessels supply blood and oxygen to the brain: the vertebral arteries and the carotid arteries.
The external carotid arteries extend up the sides of your neck, and are where you can feel your pulse when you touch the area with your fingertips. The internal carotid arteries branch into the skull and circulate blood to the front part of the brain.
The vertebral arteries follow the spinal column into the skull, where they join together at the brainstem and form the basilar artery, which supplies blood to the rear portions of the brain.
The circle of Willis, a loop of blood vessels near the bottom of the brain that connects major arteries, circulates blood from the front of the brain to the back and helps the arterial systems communicate with one another.
How Does The Balance System Work
Here, well explore a more detailed explanation of how your brains balance system works.
The Role of the Temporal Lobe
Have you ever flinched upon hearing a loud noise? You have your temporal lobes to thank. The temporal lobes are located in the cerebrum, and they help process audio and visual stimuli. Your temporal lobe has a direct line to the cerebellum by neural pathways, allowing your brain to process stimuli and react quickly by jumping away from a loud sound, for example. This is a major factor in maintaining your overall equilibrium, or sense of balance.
The Role of Semicircular Canals
Try moving your head up and down quickly. Did you recover quickly from the sudden movement? Your semicircular canals, located in your inner ear, helped with that. Your semicircular canals contain a fluid known as endolymph. This fluid moves when you move your head, activating the tiny hairs lining the canal and communicating the direction and speed of movement to your brain.
The Role of the Utricle and Saccule
Understanding which part of the brain controls balance is a key part of treating balance-related issues. The balance system is highly complex fortunately, vestibular experts have a thorough understanding of the system and its unique components.
