Question

What are the four neurons which conduct visual impulses to the visual cortex?

Answer 1

Visual cortex:

1. The principal area of the brain responsible for receiving, integrating, and processing visual information received from the retinas is known as the visual cortex.
2. It is located in the most backward part of the brain, in the primary cerebral cortex's occipital lobe.

The four neurons conducting visual impulses to the visual cortex are –

Bipolar neurons:

1. It connects the cones and rods to the ganglion cells.
2. A type of neuron with two extensions is known as a bipolar neuron or bipolar cell (one axon and one dendrite).
3. For the transmission of senses, many bipolar cells are specialized sensory neurons.

Cones and rods:

1. They are unique receptor neurons found in the retina.
2. Rods and cones are the two different categories of photoreceptors found in the human retina.
3. Cones are in charge of vision in brighter environments, whereas rods are in charge of vision in low light.

Ganglion cells:

1. Axons pass the signals to the lateral geniculate body.
2. The projection neurons of the vertebrate retina, or ganglion cells, are responsible for transmitting information from other retinal neurons to the rest of the brain.

Neurons of the lateral geniculate body:

1. Axons pass the signals to the cerebral cortex.
2. Lateral geniculate body neurons, whose axons extend to the cerebral cortex.
