In the early 2000s, the field of neuroimaging reached the stage where limited practical applications of functional brain imaging have become feasible. The main application area is crude forms of brain–computer interface. The world record for the spatial resolution of a whole-brain MRI image was a 100-micrometer volume (image) achieved in 2019.
Video of relevant anatomy Coronal slices of human brain showing the basal ganglia. White matter is shown in dark gray, gray matter is shown in light gray. Anterior: striatum, globus pallidus (GPe and GPi) Posterior: subthalamic nucleus (STN), substantia nigra (SN) The basal ganglia form a fundamental component of the cerebrum.
The dense MCA sign is a dense artery sign observed on non-contrast computed tomography (CT) of the brain and is an important early marker of acute ischemic stroke involving the middle cerebral artery territory. [1] It refers to an abnormally increased attenuation (hyperdensity) of the MCA, reflecting an intraluminal thrombus or embolus.
The putamen is the outermost portion of the basal ganglia. These are a group of nuclei in the brain that are interconnected with the cerebral cortex, thalamus, and brainstem. The basal ganglia include the striatum, substantia nigra, nucleus accumbens, and the subthalamic nucleus.
Computed tomography of the head uses a series of X-rays in a CT scan of the head taken from many different directions; the resulting data is transformed into a series of cross sections of the brain using a computer program. [1] CT images of the head are used to investigate and diagnose brain injuries and other neurological conditions, as well ...
As in images gathered through MRI, SPECT images indicated asymmetry in the presentation of abnormalities throughout the brain. [4] Additional studies have revealed the presence of perfusion anomalies in the thalamus, temporal cortex, basal ganglia, and pontocerebellar (from the pons to the cerebellum) locations within subjects' brains.

The substantia innominata, also innominate substance or substantia innominata of Meynert (Latin for unnamed substance), is a series of layers in the human brain consisting partly of gray and partly of white matter, which lies below the anterior part of the thalamus and lentiform nucleus.
Neuroferritinopathy is a genetic neurodegenerative disorder characterized by the accumulation of iron in the basal ganglia, cerebellum, and motor cortex of the human brain. Symptoms, which are extrapyramidal in nature, progress slowly and generally do not become apparent until adulthood. [ 1 ]
