Striate cortex

Striate Cortex

The Striate Cortex, also known as the primary visual cortex, is a part of the human brain responsible for processing visual information. It is located in the occipital lobe, the rearmost lobe of the cerebrum. The Striate Cortex is the simplest, earliest cortical visual area. It is highly specialized for processing information about static and moving objects and is excellent in pattern recognition.

Anatomy

The Striate Cortex is located in and around the calcarine fissure, in the interior portion of the occipital lobe. Most of it lies within the depths of the calcarine sulcus. The size of the Striate Cortex is subject to individual variability.

Function

The Striate Cortex is the first stage of cortical processing for vision. It receives a major sensory input from the lateral geniculate nucleus (LGN) in the thalamus. The LGN receives directly from the retina of the eye. The complete representation of the visual field is found in the Striate Cortex.

Clinical Significance

Damage to the Striate Cortex can cause blindness, due to the cortex's role in processing visual information. This condition is known as cortical blindness. Patients with damage to this area may experience a loss of vision in specific areas of their visual field or have a decreased ability to see colors.
