仓鸮的后外侧腹侧核是强度加工通路中的第一个双耳站。对侧刺激使VLVp细胞兴奋,同侧刺激抑制VLVp细胞。抑制强度在核内从背侧到腹侧有系统地下降。细胞选择不同的强度差异发生在一个有序的顺序,从背到腹在每个同频层。细胞核中中等深度的细胞对独立于绝对声压级的特定窄范围的耳间强度差异具有选择性。一个简单的抑制和兴奋相互作用的模型可以解释VLVp神经元的大部分反应特性。强度差异的选择性图主要基于抑制梯度。
The nucleus ventralis lemnisci lateralis pars posterior (VLVp) is the first binaural station in the intensity-processing pathway of the barn owl. Contralateral stimulation excites and ipsilateral stimulation inhibits VLVp cells. The strength of the inhibition declines systematically from dorsal to ventral within the nucleus. Cells selective for different intensity disparities occur in an orderly sequence from dorsal to ventral within each isofrequency lamina. Cells at intermediate depths in the nucleus are selective for a particular narrow range of interaural intensity differences independently of the absolute sound-pressure level. A simple model of the interaction between inhibition and excitation can explain most of the response properties of VLVp neurons. The map of selectivity for intensity disparity is mainly based on the gradient of inhibition.
