The periventricular white matter is located around the ventricles of the brain, primarily surrounding the lateral ventricles, while the subcortical white matter is found beneath the cerebral cortex of both cerebral hemispheres. These regions are crucial for communication between different brain areas, facilitating the transmission of signals. The periventricular white matter contains important pathways involved in various functions, whereas the subcortical white matter connects cortical areas with deeper structures and plays a role in motor control and cognitive processing.
A nonspecific focus of increased T2 and FLAIR signal in the right periventricular white matter typically indicates areas of potential pathology, such as demyelination, edema, or small vessel ischemia. These findings can be associated with various conditions, including multiple sclerosis, small vessel disease from chronic hypertension, or migraines. While the signal changes are nonspecific, they warrant further evaluation in the context of clinical symptoms and patient history to determine the underlying cause. It's important to consult a healthcare professional for a comprehensive assessment and appropriate imaging interpretation.
Thinking happens in various areas of the brain, primarily in the prefrontal cortex. This region is responsible for executive functions such as planning, decision-making, and problem-solving. Additionally, areas like the hippocampus are involved in memory and the cerebral cortex plays a role in processing sensory information.
The thalamus is responsible for relaying sensory information, including alert messages, to the cerebral cortex. It acts as a gateway, directing signals from various sensory systems to different areas of the brain for processing and interpretation.
The thalamus is the complex of tiny islands of gray matter within the brain that acts as a filter for incoming sensory impulses. It functions as a relay station for sensory information to the cerebral cortex and plays a key role in processing and directing sensory signals to the appropriate areas of the brain.
The corpus callosum is responsible for communication between cerebral areas, facilitating information exchange between the left and right hemispheres of the brain. Meanwhile, the thalamus serves as a relay station for transmitting information between the cerebral cortex and lower CNS centers, helping to integrate sensory and motor signals.

The white matter beneath the cerebral cortex is made up of myelinated nerve fibers that connect different regions of the brain. These fibers facilitate communication between different areas of the brain by transmitting electrical signals.
The internal capsule and the cerebral peduncles are white matter tracts that connect the cerebrum to lower brain areas such as the brainstem. These pathways are important for transmitting signals between different regions of the brain.
The association areas of the cerebral cortex enable us to interact effectively and support abstract thinking and language.
The few islands of gray matter within the interior of the cerebrum are made up of neuron cell bodies and unmyelinated axons. These areas of gray matter act as the central processing unit of the brain. Many things can affect this gray matter, such as, smoking, child abuse, alcoholism, and drugs.
The three function types within the cerebral cortex are sensory processing (receiving and interpreting sensory information), motor function (controlling voluntary movements), and higher cognitive functions (such as thinking, memory, and decision-making).
Hyperintensities refer to areas of high intensity on particular types of magnetic resonance imaging scans of the hum an brain. These small regions of high intensity are observed on T2 weighted MRI images within cerebral white matter or subcortical gray matter.
The term cerebral edema is used to describe excess fluid in certain areas of the brain. The intracellular and extracellular areas are the spaces effected.
damaging or killing neurons and neuroglia in the affected areas
Cerebral palsy occurs when certain areas of the developing brain are damaged. This can happen during pregnancy and during the birthing process. It can also happen due to lack of oxygen during birth.
