two lovley cells types in your retina, receive the light focused through the lense in your eye, and convert the light into two signals. Color, and shape, or something like that. they then traver down the optical nerve to opposite sides of your vision center. as in, the left eye's nerve goes the the right side of the vision center in your brain. you brain then unscrambles the signal into better-than- HD images for your veiwing pleasure. Exuse my strange explanation.
Light is not transmitted into the brain. Light enters the eyes, and the eyes transmit a message by way of the optic nerve into the brain, which tells the brain what the eyes see.
Light is not transmitted to the brain. Electrical impulses caused by light hitting photo receptors in the retina are transmitted to the brain by the optic nerve.
Nothing "transmits light into the brain". The brain itself has no structures capable of perceiving light, so there would be no point.

how can we say light does not need light to travel
Light Rays travel in straight paths as transverse waves. It needs no medium to travel along.
no if an object is OPAQUE then light can't travel through it (unless it has a hole in it)
Light will not travel through an opaque sponge.
Light rays travel in straight paths as transverse waves. It needs no medium to travel along.
Are you doing your homework?
More slowly. Brain waves are electrical impulses in the brain, and are VERY slow compared to electromagnetic energy in free space.
Sensory pathways tavel to the brain.

Your Brain
Optics is the study of how light (moreso Electromagnetic Radiation) travel and interact with objects (solid state physics, electrodynamics etc.). Optical illusions deal with how light is interpreted by the human brain. So optics studies how light gets to the eye, optical illusion is about how the brain perceives that light.
Light will not travel into silver.
Light can travel in a vacuum or in any transparent material
There is no way to travel at the speed of light.
As far as light can travel
Copper is opaque to light - light can not travel though it.
Light Rays travel in straight paths as transverse waves. It needs no medium to travel along.
