Vision involves both cortical and subcortical processes. The initial stages of visual processing occur in subcortical structures such as the thalamus, specifically the lateral geniculate nucleus, before signals are relayed to the primary visual cortex in the occipital lobe. Cortical areas are crucial for higher-level processing, including object recognition and spatial awareness. Thus, vision is a complex interplay of both subcortical and cortical mechanisms.
Sub- refers to below or under, cortical refers to the superficial (top) layer of a tissue/organ/structure; subcortical means the tissue/organ/structure just under the cortical layer. A common use of this term is "subcortical bone", which refers to the bone marrow.
yes epileptic seizures can be found in the sub-cortical of the Brain's of the type of seizures are all over the brain .
Rapid subcortical pathway activity refers to the quick processing of sensory information through subcortical structures in the brain, such as the thalamus and amygdala, before it reaches the cortex. This pathway allows for fast, automatic responses to stimuli, often linked to emotional and survival-related reactions. For example, it enables immediate reactions to threats, bypassing slower cortical processing. This mechanism highlights the brain's ability to prioritize speed in certain contexts, particularly in response to danger.
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.
Subcortical motor centers are located deep within the brain and include structures such as the basal ganglia and cerebellum. They play a crucial role in regulating movement, coordination, and motor learning. These regions interact with the cerebral cortex to control voluntary movements.
Lacunar strokes LACK cortical deficits. Exactly what are cortical symptomes, I do not know. =-(
Lupus can and does affect any system in the body. 40% of lupus patient develop kidney disease. Lupus patients have double the risk of cardiovascular events. Lupus can cause liver failure, cerebritis, seizures, neuropathy, bone marrow and blood issues, inflammation of the heart and lungs, and digestive problems. In lupus, the immune system attacks healthy tissue.
the function of the cortical artery is the kidenys
Cortical is a word referring to the cortex, so the subcortical region of the brain is literally 'anything beneath the cortex'; but, since the brain isn't arranged in flat layers, it may be easier to visualise this analogy: If you picture the brain as being half an orange, the outer skin (the zest) would equate to the grey matter of cerebral cortex, & the inner skin (the pith) to the white matter; everything else (the pulp & the pips of the orange) represents the subcortical structures, which include various ventricles & nuclei, the thalamus, hypothalamus, cerebellum, & the parts that make up the brainstem. Subcortical pathways enable fast, unconscious reactions; so a reflex is a subcortical action.
This is an interesting condition as neither a CAT scan nor a VEP can confirm the condition. Treatment is usually effective for cortical blindness and a series of vision stimulation activities can be performed to increase the field of vision. Children are more likely to recover from the symptoms than adults, some theorize that this is because the fibers of the optic tract may be important for the visual recovery. It has been known for adults to recover too.
In lLayman's terms, a cortical infarct is a type of stroke.
