What is the function of the uncinate fasciculus?
The uncinate fasciculus connects the orbitofrontal cortex, involved in face encoding and in processing famous names, to the temporal pole, which is crucial in naming people.
Where does the uncinate fasciculus terminate?
At this point, the uncinate fasciculus is inferior to the inferior frontal occipital fasciculus. From there, it passes into the orbital regions of the frontal lobe (BA 11 and 47), where it has a horizontally-oriented fan shape.
Where is the uncinate fasciculus?
The uncinate fasciculus is a white matter association tract in the human brain that connects parts of the limbic system such as the temporal pole, anterior parahippocampus, and amygdala in the temporal lobe with inferior portions of the frontal lobe such as the orbitofrontal cortex.
What is DTI imaging used for?
Diffusion tensor imaging tractography, or DTI tractography, is an MRI (magnetic resonance imaging) technique that measures the rate of water diffusion between cells to understand and create a map of the body’s internal structures; it is most commonly used to provide imaging of the brain.
What is Uncinate seizure?
Uncinate epilepsy is a form of psychomotor epilepsy that is initiated by a dreamy state and by hallucinations of smell and taste. Uncinate epilepsy is usually caused by a medial temporal lesion. About 50 million people have epilepsy, with 80% of that population located in developing countries.
What is the uncinate process of the pancreas?
Uncinate process – The area of the pancreas that bends backwards and beneath the body of the pancreas. The uncinate process is where 2 crucial blood vessels (the superior mesenteric artery and the superior mesenteric vein) intersect. Head – The head is the widest portion of the pancreas.
What is the position of the uncinate process?
The uncinate processes refer to a hook-shaped process, or bony protuberance, located on the lateral or posterolateral margins of the superior endplates of the cervical vertebral bodies, most commonly found at the levels of C3-C7.
What diseases can DTI detect?
CLINICAL APPLICATIONS OF DTI
- Amyotrophic lateral sclerosis.
- Multiple sclerosis.
- Neurodegenerative disorders: Parkinson’s disease and Alzheimer’s dementia.
- Epilepsy.
- Stroke.
- Traumatic brain injury.
- Spinal cord injury.
- Major depressive disorder.
How is tractography done?
In neuroscience, tractography is a 3D modeling technique used to visually represent nerve tracts using data collected by diffusion MRI. It uses special techniques of magnetic resonance imaging (MRI) and computer-based diffusion MRI. The results are presented in two- and three-dimensional images called tractograms.
What is the position of the Uncinate process?
What causes temporal lobe epilepsy?
Often, the cause of temporal lobe seizures remains unknown. However, they can be a result of a number of factors, including: Traumatic brain injury. Infections, such as encephalitis or meningitis, or a history of such infections.
Is the uncinate process pancreas part of the head?
The uncinate process is an extension of the inferior part of the head of the pancreas that projects medially and wraps around the superior mesenteric vessels.
