Document Summary
In this example, the neuron of this owl first the best at the red dot (center, right-ish) Neurons are sensitive to both itd and iids these signals reach the inferior collicus through two pathways. Converges at inferior collicus, where it forms complex maps to integrate both signals: jeffress model (cont. ) Interaural time differences involves binaural cues integration of information coming from both ears. Model postulates that there are coincidence detectors arranged in the brain, and they fire maximally when signals meet. There are two signals coming from opposing directions. Information from the left ear will hit the left coincidence detectors first and flow down to the right, and vice-versa. The coincidence detector will fire when both signals converge at the same detector. Axons lengths act as delay lines: the longer the axon, the longer it takes for information to propagate. E. g. if sound is coming from directly in front of the individual.
