Retina

The light-sensitive layer at the back of the eye that converts light into neural signals, which are then transmitted to the brain for visual perception.

Key Functions:

• Contains photoreceptor cells (rods and cones) that detect light.
• Converts light into electrical signals.
• Initial processing of visual information.
• Transmits signals to the lateral geniculate nucleus via the optic nerve.

Interacting Systems & Components:

• Eye (located in)
• Photoreceptors (rods, cones)
• Optic Nerve (transmits signals to brain)
• Lateral Geniculate Nucleus (LGN) (projects to)
• Retinohypothalamic Tract (direct projection to SCN)
• Vision (essential for)
