Cortical stimulation mapping led to the development of a homunculus for the motor and sensory cortices, which is a diagram showing the brain's connections to different areas of the body. An example is the cortical homunculus of the primary motor cortex and the somatosensory cortex, which are separated by the central sulcus.
[14] [15] About two months later, scientists reported that they created the first complete neuron-level-resolution 3D map of a monkey brain which they scanned via a new method within 100 hours. They made only a fraction of the 3D map publicly available as the entire map takes more than 1 petabyte of storage space even when compressed.
Structural magnetic resonance imaging (structural MRI) of a head, from top to base of the skull. The first chapter of the history of neuroimaging traces back to the Italian neuroscientist Angelo Mosso who invented the 'human circulation balance', which could non-invasively measure the redistribution of blood during emotional and intellectual activity.
Imaging is an important method for diagnosing CNS tumors and determining their location. The location is informative both for identifying the type of tumor and for determining how to treat it. Magnetic resonance imaging (MRI) and computed tomography (CT) scans are the most commonly used imaging technologies for diagnosis of CNS tumors. MRI ...
Neuro-oncology is the study of brain and spinal cord neoplasms, many of which are (at least eventually) very dangerous and life-threatening (astrocytoma, glioma, glioblastoma multiforme, ependymoma, pontine glioma, and brain stem tumors are among the many examples of these).
Tumor markers alone can't be used for diagnostic purposes, due to lack of sensitivity and specificity. [5] The only approved diagnostic method for cancer is with a biopsy. Detects reoccurring cancers; Tumor markers can detect reoccurring cancers in patients post-treatment. [4]
Molecular pathology is commonly used in diagnosis of cancer and infectious diseases. Molecular Pathology is primarily used to detect cancers such as melanoma, brainstem glioma, brain tumors as well as many other types of cancer and infectious diseases. [23]
