摘要：
Currently, there is controversy around whether rats can use interaural time differences ( ITDs) to localize sound. Here, naturalistic pulse train stimuli were used to evaluate the rat's sensitivity to onset and ongoing ITDs using a two-alternative forced choice sound lateralization task. Pulse rates between 50Hz and 4.8 kHz with rectangular or Hanning windows were delivered with ITDs between +/-175 mu s over a near-field acoustic setup. Similar to other mammals, rats performed with 75% accuracy at similar to 50 mu s ITD, demonstrating that rats are highly sensitive to envelope ITDs. (C) 2019 Acoustical Society of America
