It is called tumefactive as the lesions are "tumor-like" and they mimic tumors clinically, radiologically and sometimes pathologically. [1] These atypical lesion characteristics include a large intracranial lesion of size greater than 2.0 cm with a mass effect, edema and an open ring enhancement. A mass effect is the effect of a mass on its ...
A neural pathway connects one part of the nervous system to another using bundles of axons called tracts. The optic tract that extends from the optic nerve is an example of a neural pathway because it connects the eye to the brain; additional pathways within the brain connect to the visual cortex.
Much work is being done in nerve regeneration for the most severely damaged neural pathways. Neurocognitive techniques, such as cognitive rehabilitation therapy , provide assessment and treatment of cognitive impairments from a variety of brain diseases and insults that cause persistent disability for many individuals.
A central nervous system tumor (CNS tumor) is an abnormal growth of cells from the tissues of the brain or spinal cord. [1] CNS tumor is a generic term encompassing over 120 distinct tumor types. [ 2 ]
A number of online neuroscience databases are available which provide information regarding gene expression, neurons, macroscopic brain structure, and neurological or psychiatric disorders. Some databases contain descriptive and numerical data, some to brain function, others offer access to 'raw' imaging data, such as postmortem brain sections ...
The tuberoinfundibular pathway not only regulates hormonal balance but also influences locomotor networks in the brainstem and spinal cord. Modulating motor control and coordination, showcasing the interconnected nature of neural circuits in the brain. motor function. restless legs syndrome; Incertohypothalamic pathway

Conventional CT and MRI should be performed with cuts of 10 mm or less in slice thickness contiguously. Spiral CT should be performed using a 5 mm contiguous reconstruction algorithm. This applies to tumors of the chest, abdomen and pelvis. Head and neck tumors and those of extremities usually require specific protocols.
