(anatomy) the outer layer of the anterior part of the brain, called cerebrum, containing gray matter
The cortex, also known as the neocortex, is a highly complex and layered structure that forms the outer surface of the brain. It is composed of billions of neurons and is responsible for many essential functions such as conscious awareness, perception, voluntary movement, and higher-level cognitive processes. The cortex is divided into different regions, each with specialized functions, such as the frontal lobe involved in executive functions and decision-making, the parietal lobe involved in sensory processing, the temporal lobe involved in memory and auditory processing, and the occipital lobe involved in visual processing. The intricate organization of the cortex allows for intricate connections and information processing, making it a critical component of the central nervous system.
- The cerebral cortex is the outer layer of the brain responsible for higher cognitive functions such as thinking, memory, and perception.
- The prefrontal cortex, located in the frontal lobe, plays a key role in decision-making, impulse control, and social behavior.
- Damage to the motor cortex can result in paralysis or weakness on the opposite side of the body.
- The visual cortex, located in the occipital lobe, processes visual information received from the eyes.
- The somatosensory cortex, located in the parietal lobe, receives and processes sensory information from the skin, muscles, and joints.

the tissue forming the outer layer of an organ or structure in plants and animals, such as the renal cortex of a kidney or the cortical cells beneath a stem's epidermis
- During the microscopy session, the students identified the vascular bundles and surrounding cortex in the root cross-section.
- A biopsy of the adrenal cortex revealed abnormal hormone–producing cells.
- In woody plants, the cortex lies between the phloem and the periderm, contributing to bark thickness.
- The renal cortex contains glomeruli that filter blood before it passes into the kidney's medulla.
- Fungal pathogens often invade the plant cortex first, disrupting water and nutrient transport.

the layer of lens fibers surrounding the central nucleus of the eye's crystalline lens, crucial for flexibility and light refraction
- Slit-lamp examination revealed early opacities in the lens cortex, indicating the onset of a cortical cataract.
- During cataract surgery, the surgeon carefully removed the hardened lens cortex before inserting the intraocular lens.
- Age-related changes in the lens cortex can reduce accommodation, leading to presbyopia.
