Visual information in the form of electrical signals travels along the optic nerve from the eye to the brain. These signals are generated by the photoreceptor cells in the retina and are then transmitted through the optic nerve to be processed in the visual cortex of the brain, allowing us to perceive and interpret what we see.
Each light-sensitive receptor cell generates a signal in its attached optic nerve fibre, for transmission to the brain where the combined signals are processed to build up the image itself in our minds.
In most cases signals are sent to the brain through the nervous system. Individual signals are transfer from neuron to neuron in the form of chemical and electrical energy that eventually reach the brain.
stimuli are converted into electronic signals. Such electronic signals travel by a huge network of nerves throughout the body. These signals converge to the brain, where sensory neurons interpret them and send back an "order" through the Central Nervous System, to the correspondent point of the body where the stimulus has happened. Such "order" may refer to the release of defence cells, or simply tell your arm to touch the point of the stimulus,in order to calm you down, as a simple example. The signal that flows through the nerve, uses a mineral, magnesium, as a basis to conduct the electronic signal. Sodium is another mineral that participates of the process. Such travel may take only miliseconds to reach the brain and to come back.
auditory nerve
optic nerve
Vision takes place in the eye's retina, where light is converted into electrical signals. These signals are then transmitted to the brain via the optic nerve, where they are processed and interpreted to form visual perceptions.
The optic nerve carries signals from the eyes to the brain.

The optic nerve carries signals (images) from the retina to the brain.

definitely the brain. The olfactory nerve transmits the signals straight to brain.
The nerve that carries the signals to the brain is the ossicles
