The part of your brain that controls your vision resides in the Occipital Lobe and is called the Visual Cortex. What Part of the Brain Is Responsible for Vision As soon as the information passes from the optic nerve to the remainder of the brain, it is sent to the occipital lobe, where vision is processed. Nov 04,  · Occipital lobe- located at the back of the head, this section occupies some 20% of the brain’s overall capacity and is responsible for vision and being able to visualize scenes never actually.

Vision is an intricate function of the brain that extends from the front to the back of the head. To produce vision, the eyes record details and send it through the optic nerve to be processed by the occipital lobe. The brain also integrates other information, such as sensory stimuli, to result in the application of sight, such as picking up an item. Problems with vision, such as vision gaps, can result from damage to specific parts of the brain.

When light reaches the retina in the eye and an image is developed, it moves to the remainder of the brain through the optic nerve. The optic nerve is the second cranial nerve, and is the connection between the brain and eyes. Damage to the optic nerve avoids any info from being sent from the eyes to the remainder of the brain. The Canadian Institutes of Health Research specifies that info from the left eye goes to the right hemisphere and vice versa; this is because the optic nerve crosses at the optic chiasm, causing the optic nerve from each eye to send its details to the opposite side what is meant by evolution the brain.

As soon as the information passes from the optic nerve to the remainder of the brain, it is sent to the occipital lobe, where vision is processed. The occipital lobe is located in the back of the brain, above the cerebellum, and forms the center of the visual perception system, according to the Centre for Neuro Skills.

Each hemisphere has its own occipital lobe; therefore, each occipital lobe processes the information sent to that particular hemisphere. The occipital lobe controls how an individual views sight, so damage to this brain section can result in visual field cuts, and problems identifying color or movement of a things. The last part of the brain associated with vision is the visual cortex, where sensory and motor info is incorporated with vision. The Canadian Institutes of Health Research states that several visual pathways are included.

Optic Nerve

Apr 01,  · The information from the retina — in the form of electrical signals — is sent via the optic nerve to other parts of the brain, which ultimately process the image and allow us to see. Thus, the visual process begins by comparing the amount of light striking any small region of the retina with the amount of surrounding light. To be more specific, two brain regions are in charge of these tasks: one region to analyze the shape of objects and another to analyze their spatial features (i.e. size, location, orientation). Considering the amount of information that needs to be processed to accurately analyze a visual scene, we can say that vision is a very complex. The visual field of each eye has the left and right hemifields. optic chiasm, the visual signals from the left hemifields of both eyes are sent to the right hemisphere of the brain, while the signals from the right hemifields of both eyes are sent to the left hemisphere of the brain. So each.

The human brain is one of the most largest and 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 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.

The cerebrum is the largest part of the human brain. It has a rough surface cerebral cortex with gyri and sulci. It can also be divided into 2 parts: the left hemisphere and the right hemisphere. Although the hemispheres look identical, the left and right hemispheres have very specific functions. While the left hemisphere logical side controls language and speech, the right hemisphere creative side is responsible for translating visual information.

According to the function, the cerebrum is also further divided into 4 different lobes: frontal lobes, parietal lobes, temporal lobes, and occipital lobes.

Each lobe has different functions:. The frontal lobe rests just below the forehead and controls our reasoning, organizing, our ability to speak, solve problems, pay attention, and our emotions. The parietal lobe lies at the upper rear of our brain.

This lobe manages our complex behaviors, including the 5 senses: touch, vision, and spatial awareness. The occipital lobe is located at the rear of our brain. This lobe is responsible for our visual awareness, including visual attention, optical recognition, and spatial awareness.

It also controls our ability to interprets body language like facial expressions, gestures, and body postures. Your temporal lobe sits close to your ears and is associated with interpreting and translating auditory stimuli. For example, your temporal lobe allows you to focus on one voice in a loud party. This lobe also helps you understand oral language, general process knowledge, and stores your verbal and visual memory.

The cerebellum, also known as the little brain, is located in the back of the brain. It sits just below the occipital lobes and on top of the pons. Just like the cerebrum, the cerebellum has two equal hemispheres and a wrinkly surface. Although the cerebellum is small, it contains numerous neurons. It can help coordinate the movement of body muscles, especially the fine movement of hands and feet. The function of the cerebellum also includes maintaining posture, equilibrium, body balance, and even speech.

The brain stem is the posterior part of the brain that connects the brain with the spinal cord. Brain stem works together to regulate essential life functions, including body temperature, breathing, heartbeat, and blood pressure. In addition, the brain stem coordinates the fine movement of the face and limbs. Functions of this area include sneezing, vomiting, swallowing, and movement of the eyes and mouth. The brain stem comprises parts of the midbrain, pons, and medulla, all of which have specific functions.

The midbrain consists of the tegmentum and the tectum, located in the mouth of the brain stem. It plays a key role in controlling voluntary motor function and transferring messages.

In addition, it controls eye movement and processes auditory, visual information, and eye movement. The pons is the largest structure in the brain stem and is found above the medulla and underneath the midbrain, and in front of the cerebellum. It functions as a bridge between several parts of the nervous system, including the cerebrum and cerebellum. The pons also contains many vital nerves such as. The medulla is a cone-shaped structure located in front of the cerebellum.

The prominent role of the medulla oblongata is regulating involuntary autonomic functions, including breathing, digestion, sneezing, swallowing, and heart rate. The limbic system is a complex brain structure that lies deep in the cerebrum. It contains the thalamus, hypothalamus, hippocampus, and amygdala.

The thalamus is a small mass of grey matter that relays sensory information from the spinal cord, brainstem, and other parts of the brain to the cerebral cortex. The thalamus is a relay station for signals received by the human body from the outside to enter the brain.

In addition, it is also related to consciousness, memory, and sleep. The hypothalamus is a part of the brain that sits right below the thalamus. Although the hypothalamus is a tiny part of the brain, it has one of the most crucial and busiest roles. The primary function of the hypothalamus is maintaining homeostasis in the body. The amygdala is a small, almond-shaped structure in the limbic system that processes strong emotions like fear, aggression, and anxiety.

The amygdala is located close to the hippocampus. It contains a large number of receptor sites that can also perceive certain emotions and the storing and retrieving of emotional memories.

The principal role of the hippocampus is forming, organizing, and storing short and long-term memories. The hippocampus also helps form new memories and links emotions, feelings, and sensations such as specific smell and sound to these memories. The skull is a fusion of bones that protects the brain, the brainstem, and outlines the face. The 8 bones that protect your bones from injury include:.

Other conditions that could affect the brain include:. Brain aneurysm: When an artery in the brain swells, it could lead to a brain aneurysm. If the aneurysm ruptures, it could cause a stroke.

Brain tumor: When any tissue in your brain starts growing abnormally, it could be symptoms of benign or malignant cancer. Intracerebral hemorrhage: Bleeding inside the brain can cause difficulty speaking or difficulty walking.

Cerebral edema : Electrolyte imbalance in the brain could lead to swelling of the brain tissue. Glioblastoma: Glioblastoma is a brain tumor that develops very rapidly and creates pressure on the brain.

Pro tip: Glioblastoma is usually aggressive and could be very difficult to cure. Meningitis: When the lining around the brain or spinal cord becomes inflamed from an infection, you may have meningitis.

Other symptoms associated with meningitis include; headache, fever, sleepiness, neck pain, and stiff neck. Encephalitis: Encephalitis usually arises when tissue in the brain becomes inflamed. Traumatic brain injury : A severe head injury could lead to permanent brain damage. Other symptoms include mental impairment and personality, and mood changes.

People with epilepsy may also experience seizures. Dementia: When a nerve cell in the brain starts malfunctioning or degenerating slowly, it could lead to dementia. Strokes and alcohol abuse could also cause brain dementia. Here, the nerves in the brain degenerate, causing progressive dementia. Brain abscesses are usually caused by bacteria and may require either antibiotics or surgical removal.

As we age, certain areas of the brain start to shrink, especially areas that are important to learning and storing memories. The good news is — You can follow some tips to keep your brain in excellent health and slow down mental decline.

Here are some tips you can use to maintain a healthy brain. Doing mental exercises like doing crossword puzzles, reading regularly, or learning a new language helps improve your mental fitness. Doing mental exercises stimulate nerve cells and may even trigger the development of new brain cells. Injuries to the head can cause brain concussions, other severe brain injuries.

Exercising improves blood flow in your body, including your brain. Moderate exercise also lowers blood pressure, reduces mental stress, and could trigger the development of new nerve cells.
