1.The Jeffress Model
The Jeffress model is a neurocomputational model that explains how auditory systems can register and analyze small differences in the arrival time of sounds at the two ears in order to estimate the direction of sound sources in the azimuthal plane.
The Jeffress Model has long been a popular model for trying to exlpain how the mammalian MSO or the bird nucleus laminaris may extract interaural time differences for sound localization. The Jeffress model posits a “delay line and coincidence detector” arrangement which is illustrated in the animation shown here. The animation nicely conveys the appeal of the Jeffress model. Due to a systematic delay line arrangement and a requirement for precise synchrony in the activation of MSO neurons, different parts of the MSO become sensitive to sounds from particular directions. But note that the cartoon shown here is in many ways “biologically naive”, oversimplifying the anatomy and physiology. Whether the Jeffress model, such as it is shown here, is really a good description of the operation of the mammalian MSO is becoming increasingly controversial.
