In cats, the technique of localization parameter of dichotic sounds showed the binaural stimulation to be more effective than the monaural one. The interaural difference in intensity and time modified characteristics of neuronal responses in the sensorymotor cortex (SMC), the responses being most obvious in 67--88% of cases at the minor, approximating zero, temporal and amplitude interaural shifts. The SMC neurons altered their spontaneous activity in response to signals simulating movement of the sound source in horizontal plane. 74% of these neurons seemed to prefer the velocity up to 48 degrees/sec. These features of the SMC neuronal responses can be of major importance for formation and regulation of the cortical programs for willed motor acts of the animals in the course of acoustic orientation.
在猫身上，双耳分听声音定位参数技术表明，双耳刺激比单耳刺激更有效。强度和时间上的双耳差异改变了感觉运动皮层（SMC）中神经元反应的特征，在67%-88%的情况下，当较小的、接近零的时间和幅度双耳偏移时，反应最为明显。SMC神经元会因模拟声源在水平面上移动的信号而改变其自发活动。这些神经元中有74%似乎更喜欢高达48度/秒的速度。在听觉定向过程中这些SMC神经元反应的特征对于动物随意运动行为的皮层程序的形成和调节可能具有重要意义。
