POSTHERPETIC NEURALGIA PATIENTS SHOW ABNORMAL LOCAL BRAIN ACTIVITY BEYOND PAIN MATRIX: A RESTING-STATE FUNCTIONAL MRI STUDY PurposeTo explore the brain microstructural and functional changes in patients with postherpetic neuralgia (PHN).Materials and methods12 PHN patients and 1...

Intensity-based features are useful in differentiating between normal and abnormal tissue regions due to their distinct intensity profiles. Texture-based features describe the spatial arrangement of intensities and reflect the local patterns in the image. Common texture-based features include the gray-...
In addition, they classified these features with the proposed weighted Gaussian Naïve Bayes as normal and abnormal (stroke) classes. As a result, they obtained a 99.32% accuracy, 96.87% sensitivity, and 98.82% F1 measure using the proposed method. Subuddhi et al. [9] used an MRI, which...
When the DNA is damaged in this way, the abnormal cells multiply and grow faster than your normal cells, which forms the tumor. Usually, environmental exposure adds to the DNA damage. Sometimes, people are born with DNA damage and they get tumors at a very young age. Brain Tumor Risk ...
For example, the tumor may abut or wrap around critical normal tissues. Damage to these tissues during surgery could cause the patient significant disability.Stereotactic surgery, which uses computers and imaging devices to create three-dimensional pictures of the brain, can be used to remove tumors...
the problems can lead to long-term hormone insufficiency and loss of vision. Malignant tumor cells are abnormal cells that increase uncontrolled and irregularly. Normal tissues can be compressed, infiltrated, or destroyed by these tumors. The most common variety of malignant brain tumors is noted to...
structural and functional MRI studies combined with behavioral data16,25,28led us to recently propose a hypothesis that GD is characterized by a functional disconnection between systems in the brain that process the perception of self (“self-referential”), and those that mediate own-body ...
Abnormal salience processing has been suggested to contribute to the formation of positive psychotic symptoms in schizophrenia and related conditions. Previous research utilising reward learning or anticipation paradigms has demonstrated cortical and subcortical abnormalities in people with psychosis, specifically...
are many kinds of brain tumour, some are benign or non-cancerous , in other words, is the overgrown cells that produce mass, but cell themself is normal.Some are malignant or cancerous, this means the masses can posed by abnormal cells that will continue to spread and invade other tissue...
