Document Summary
Each major division of the brain processes one or more types of sensory information: ex: midbrain receives visual information and the medulla oblongata receives input for sound and taste. Information about balance and equilibrium is processed primarily in the cerebellum: these pathways project to the thalamus, which acts as a relay and processing station before passing information on to the cerebrum. Location of the stimulus coded according to which receptive fields are activated sensory regions of the cerebrum are highly organized with respect to incoming signals. But, the 3 secondary neurons do not all respond with the same response. The secondary neuron closest to the stimulus suppresses the response of secondary neurons lateral to it (neurons on either side of it) where the stimulus is already weaker. The simultaneously allows the primary neuron closest to the stimulus" pathway to proceed without interference.
