What does the posterior complex of the thalamus do?
The posterior region includes the large pulvinar nucleus, which makes up approximately 30 percent of the thalamic volume in humans. Its primary functions relate to multisensory integration and behavioral orientation. As such, it has strong connections with the parietal association cortex.
What is the main function of the thalamus?
Your thalamus is your body’s information relay station. All information from your body’s senses (except smell) must be processed through your thalamus before being sent to your brain’s cerebral cortex for interpretation. Your thalamus also plays a role in sleep, wakefulness, consciousness, learning and memory.
What is the role of the dorsal thalamus?
The dorsal thalamus, usually simply referred to as the thalamus is a subdivision of a brain area called the diencephalon, which also includes the eptithalamus, the ventral thalamus and the subthalamic thalamus. The thalamus relays sensory impulses from receptors in various parts of the body to the cerebral cortex.
Is the thalamus anterior or posterior?
The thalamus is the largest structure deriving from the embryonic diencephalon, the posterior part of the forebrain situated between the midbrain and the cerebrum.
What happens when thalamus is damaged?
While thalamus damage primarily causes sensory problems, it can also lead to behavioral and cognitive changes. For example, many patients with a thalamus injury have incorrect speech patterns and can struggle to find the right words. Others display apathy and memory problems.
What disorders are associated with the thalamus?
Disorders of the centrally located thalamus, which integrates a wide range of cortical and subcortical information. Manifestations include sensory loss, MOVEMENT DISORDERS; ATAXIA, pain syndromes, visual disorders, a variety of neuropsychological conditions, and COMA.
What happens when your thalamus is damaged?
What are the symptoms of thalamic syndrome?
Thalamic pain syndrome or central post-stroke pain can occur when there are disruptions of one of the pathways of the brain that affects the sensation of temperature. There can be burning or tingling pain. Also, significant discomfort with temperature changes is a concern for thalamic pain syndrome following a stroke.
What happens if you have damage to the thalamus?
What happens if there is damage to the thalamus?
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).
Is a thalamic infarction a stroke?
A thalamic stroke is a type of lacunar stroke, which refers to a stroke in a deep part of your brain. Thalamic strokes occur in your thalamus, a small but important part of your brain.
What does a thalamic stroke cause?
A thalamic stroke may result in memory loss (vascular thalamic amnesia) that can affect long- or short-term memory. It can also be accompanied by a shift in personality. Changes in attention. Attention, along with memory, is a high-level cognitive skill that the thalamus plays a role in.
What are the symptoms of a stroke in the thalamus?
Symptoms of Thalamic Strokes
- Weakness on one side of the body.
- Issues with vision.
- Difficulty swallowing.
- Loss of memory.
- Burning.
- Confusion.
- Problems thinking or with judgment.
- Feelings of agitation.
