The term “ganglion cell” usually refers to retinal ganglion cells. Retinal ganglion cells receive visual information from photoreceptors in the retina and transmit nerve impulses to the visual cortex of the brain via the optic nerve.
What are ganglion cells?
Ganglion cells are cells of the Ganglion, this is a collection of nerve cells in the peripheral nervous system. However, the term “ganglion cell” is usually used to refer to retinal ganglion cells (RGCs), which are located in the retina of the eye.
Location of the ganglion cells
The term “ganglion cell” can be used to refer to any type of cell that is present in the Ganglion. The ganglion is any group of neurons in the peripheral nervous system (PNS). A group of neurons in the central nervous system (CNS) is called a. designated Core.
When people say “ganglion cell” they are usually referring to cells in the ganglion layer in the retina of the eye. These are also known as Ganglion cells of the retina (RGCs) and their key function is to convey visual information to the brain’s visual cortex.
Structure of the retina
The human retina contains over a million RGCs that are located near the inner surface (or ganglion cell layer) of the retina. They help to form synapses bipolar and amacrine cells by doing inner plexiform layer (IPL) the retina. Bipolar cells are Interneurons, and also from synapses with Photoreceptor cells called Rods and Cone.
Photoreceptors are specialized neurons that convert light signals into nerve impulses. Rods are the photoreceptors that allow us to see in the dark. They contain a light-sensitive pigment and can detect shapes and movements in very low light. However, they are not color sensitive, which makes it difficult to see colors in a dark environment.
Cones are not as sensitive to light, but they can see colors better than chopsticks. Cones work best in bright conditions and are activated by either red, blue, or green light. When light hits a cone, it sends a signal through the bipolar cells, to the RGCs, and into the brain, where it is processed and interpreted as color.
Function of the retinal ganglion cells
The function of the RGCs is to transmit visual information collected by photoreceptors in the retina to the brain. When photoreceptors in the eye are stimulated by light, they send a signal to the bipolar cells, which in turn relay it to the ganglion cells of the retina. The axons of the erythrocytes form the optic nerve that connects the retina with the visual cortex of the brain.
The optic nerve leaves the fundus through an opening called Optical medium, and forwards nerve impulses to the brain, where they are processed and interpreted as images.
