Each of your spinal tracts carries a specific type of information. For example, your lateral spinothalamic tract carries information related to pain and temperature. If part of your medulla becomes damaged, it can lead to an inability to relay a specific type of message between your body and brain. The types of information carried by these spinal tracts include:.
Your motor neurons cross from the left side of your brain to the right side of your spine in your medulla. If you damage the left side of your medulla, it will lead to loss of motor function to the right side of your body. Similarly, if the right side of the medulla is damaged, it will affect the left side of your body. Damage to your medulla oblongata can lead to:. Various types of problems can develop if your medulla becomes damaged because of a stroke , brain degeneration, or a sudden head injury.
The major symptoms are:. Wallenberg syndrome is also known as lateral medullary syndrome. It frequently results from a stroke near the medulla.
Common symptoms of Wallenberg syndrome include:. Symptoms include:. Bilateral medial medullary syndrome is a rare complication from a stroke. Reinhold syndrome or hemimedullary syndrome is exceedingly rare. There are only about 10 patients in the medical literature that have developed this condition. Your medulla oblongata is located at the base of your brain, where the brain stem connects the brain to your spinal cord.
It plays an essential role in passing messages between your spinal cord and brain. If your medulla oblongata becomes damaged, it can lead to respiratory failure , paralysis , or loss of sensation. Here's what left brain vs. A stroke occurs when blood supply to the brain is interrupted. The way a stroke affects the brain depends on which part of the brain suffers damage….
Your doctor may find a choroid plexus cyst during a routine prenatal ultrasound. These cysts usually resolve on their own and rarely lead to…. Dysmetria is a lack of coordination caused by the cerebellum not functioning properly. Discover its causes and…. In the body there are two deep temporal arteries. These arteries are called the posterior and anterior deep temporal arteries.
Theta brain waves are slower than gamma, beta, and alpha waves, but faster than delta waves. Your brain produces five different types of brain waves that move at a different speeds. Gamma waves are the fastest brain waves. Your brain tends to…. It is estimated that every year almost two million brain stem injuries occur and very few cases recover from the injury.
What happens if the brain stem is severed? The brain-stem can become compressed due to swelling, leading to hemorrhaging and stroke. This may result in speech impairment, breathing difficulties, including sleep apnea and difficulty swallowing. In acute cases, there may be personality changes and memory loss. What behaviors would be affected if the cerebellum was damaged?
Damage to the cerebellum can lead to: 1 loss of coordination of motor movement asynergia , 2 the inability to judge distance and when to stop dysmetria , 3 the inability to perform rapid alternating movements adiadochokinesia , 4 movement tremors intention tremor , 5 staggering, wide based walking ataxic gait.
Does medulla oblongata control anger? This is not entirely true though; the more complex emotion of anger primarily derives from activity in the hypothalamus and amygdala. However, the medulla oblongata controls physiological processes like heart rate and blood pressure, physiological responses that are tightly associated with anger and aggression.
What does the medulla oblongata control? The medulla oblongata, also known as the medulla, directly controls certain ANS responses, such as heart rate, breathing, blood vessel dilation, digestion, sneezing, swallowing and vomiting. It is a portion of the brainstem, located just below the pons and just above the spinal cord.
What happens if the midbrain is damaged? Damage to the midbrain can result in a wide variety of movement disorders, difficulty with vision and hearing, and trouble with memory. Because the midbrain houses the hypothalamus, it also plays a major role in automatic body functions. Does the medulla oblongata control emotions? Medulla Oblongata: Contains centers for the control of vital processes such as heart rate, respiration, blood pressure, and swallowing.
Limbic System: A group of interconnected structures that mediate emotions, learning and memory. Occipital Lobe: Helps process visual information. What affects the medulla? The medulla contains the cardiac, respiratory, vomiting and vasomotor centers and therefore deals with the autonomic functions of breathing, heart rate and blood pressure as well as the sleep wake cycle.
What is Pons responsible for? Besides the medulla oblongata, your brainstem also has a structure called the pons. The pons is a major structure in the upper part of your brainstem. It is involved in the control of breathing, communication between different parts of the brain, and sensations such as hearing, taste, and balance.
What part of the brain controls abstract thinking? The frontal lobe affects human behavior by controlling decision-making, planning and reasoning. According to the press release, the study, published in the March 1 issue of Nature Neuroscience, is among the first to show that different areas of the frontal lobe correspond with varying degrees of abstract thought.
What happens if thalamus is damaged? Damage to a portion of the thalamus is associated with risk of coma. Damage in a portion of the thalamus can lead to sensory changes in a body part. Damage here can also cause movement disorders, lack of movement motor disturbances. Can a person who is brain dead open their eyes?
