[Sense organs: selective projections and control of behaviors].
Some aspects of comparative sensory physiology are reviewed in the context of the historical development. Emphasis is placed on the concepts how spatial and temporal stimulus patterns are processed into nervous excitation patterns and projected in the brain: Both receptor organs and neuron networks may act as selective filters for certain features of the stimulus situation. Neural projections represent not only the spatial distribution of the stimulus pattern but also other parameters. Excitation patterns resulting from the stimulus situation are compared in the neuronal networks with patterns inherited, learned, or inherited and modified by learning. The result of this comparison may then trigger the behavior necessary under the conditions present.
