The answer is the thalamus.
The thalamus acts as a relay station, relaying information between different subcortical areas and the cerebral cortex.
The thalamic receives sensory signals, organizes, and sends them to the right primary cortical area. For example, Jeanne is watching the sunset: The retina sents input to the thalamus, which in turn sends the input to the visual cortex (in the occipital lobe).
