Cerebellum. The cerebellum is located at the back of the brain beneath the occipital lobes. It is separated from the cerebrum by the tentorium (fold of dura). The cerebellum fine tunes motor activity or movement, e.g. the fine movements of fingers as they perform surgery or paint a picture.

brain stem

The area of the brain with the greatest amount of recent evolutionary change is called the neocortex.

occipital lobe

Each half receive sensory information though, curiously, from the opposite side of the body. Thus the right eye goes to the left brain and vice versa. The exception is the nose: the right nostril goes to the right brain. When we talk about the ‘left brain’, we usually actually mean the dominant hemisphere.

Yes, they can. Although eye problems typically stem from conditions unrelated to brain tumors—such as astigmatism, cataracts, detached retina and age-related degeneration—they can sometimes be caused by tumors within the brain. Brain tumors can lead to vision problems such as: Blurred vision.

A neurological exam tests the twelve cranial nerves by subtly dissociating their functions. Shining a small flashlight into one eye, for example, can distinguish between damage to CN II (the optic nerve) and damage to CN III (the oculomotor nerve).

The leading causes of blindness and low vision in the United States are primarily age-related eye diseases such as age-related macular degeneration, cataract, diabetic retinopathy, and glaucoma. Other common eye disorders include amblyopia and strabismus.

What are the main causes of blindness?

• Uncorrected refractive errors. Uncorrected refractive errors, such as myopia, hyperopia or astigmatism, can all cause severe visual impairment.
• Cataracts.
• Age-related macular degeneration.
• Glaucoma.
• Diabetic retinopathy.

1. Glaucoma: Abrupt and severe pain in your eyes and seeing halos can be signs of glaucoma. Glaucoma is an eye condition caused by elevated levels of fluid pressure in the eyes, which can potentially damage the fragile fibers of the optic nerve. This damage is irreversible and can even lead to blindness.

If your number is between -0.25 and -2.00, you have mild nearsightedness. If your number is between -2.25 and -5.00, you have moderate nearsightedness. If your number is lower than -5.00, you have high nearsightedness.

Many eye diseases are not curable at this time, but treatment can improve quality of life for patients and slow progression of the damage. Here are three examples of eye diseases that are not curable but nevertheless treatable. Patients with these conditions can live full and independent lives.

According to their findings, the stress hormone cortisol can actually damage the eye and brain and disrupt blood flow in these parts of the body. They believe that stress may be one of the major causes of eye diseases, like glaucoma, a group of diseases that damages the optic nerve and can lead to blindness.

Eye problems, known as thyroid eye disease or Graves’ ophthalmopathy, affect around 1 in 3 people with an overactive thyroid caused by Graves’ disease. Problems can include: eyes feeling dry and gritty. sensitivity to light.

Which nutrients are harmful?

• soy foods: tofu, tempeh, edamame, etc.
• certain vegetables: cabbage, broccoli, kale, cauliflower, spinach, etc.
• fruits and starchy plants: sweet potatoes, cassava, peaches, strawberries, etc.
• nuts and seeds: millet, pine nuts, peanuts, etc.

Thyroid gland

1. Fatigue.
2. Increased sensitivity to cold.
3. Constipation.
4. Dry skin.
5. Weight gain.
6. Puffy face.
7. Hoarseness.
8. Muscle weakness.

Thyroid Superfoods

1. Roasted seaweed. Seaweed, such as kelp, nori, and wakame, are naturally rich in iodine–a trace element needed for normal thyroid function.
2. Salted nuts. Brazil nuts, macadamia nuts, and hazelnuts are excellent sources of selenium, which helps support healthy thyroid function.
3. Baked fish.
4. Dairy.
5. Fresh eggs.

What common symptoms can happen with thyroid disease?

• Experiencing anxiety, irritability and nervousness.
• Having trouble sleeping.
• Losing weight.
• Having an enlarged thyroid gland or a goiter.
• Having muscle weakness and tremors.
• Experiencing irregular menstrual periods or having your menstrual cycle stop.

Problems with the thyroid can be caused by: iodine deficiency. autoimmune diseases, in which the immune system attacks the thyroid, leading either to hyperthyroidism (caused by Graves’ disease) or hypothyroidism (caused by Hashimoto’s disease) inflammation (which may or may not cause pain), caused by a virus or …

You may feel fatigue, gain weight, be perpetually cold, experience constipation, have fertility issues, brain fog, or have aching joints and muscles, all of which are symptoms of Hashimoto’s. (Thyroid hormone levels can also be too high, a condition called hyperthyroidism, which may be caused by Grave’s disease.)
