水下振动源同时提供声学和水动力扰动。由于振动偶极子源是较差的声波投射源，大多数研究人员认为这类源与侧线系统(LL)最相关。水声原理和实验研究都表明，振动偶极子源对鱼类的内耳也是一种强有力的刺激。采用非条件定向、差分条件反射和非差分经典条件反射三种方法，研究了斑点叉尾(Cottus Bairdi)对振动源的反应。定向反应由LL输入主导，并被LL药物失活消除。简单的条件反射依赖于其他系统的输入，不受LL失活的影响。差异条件反射改变了行为控制，而斯卡平可以被调节为忽略底物产生的振动，只对耳朵的水声刺激做出反应。斑驳的斯卡宾的侧线和内耳不一定表现出范围分割，因为这两个系统都在与动物相似的距离上运行(在1.5个身体长度内)，并对许多相同的来源做出反应。振动偶极子源产生复合刺激，同时激活多个八伏神经系统，动物在不同的行为任务下以不同的方式利用这些通道。
An underwater vibratory source simultaneously presents acoustic and hydrodynamic disturbances. Because vibratory dipole sources are poor sonic projectors, most researchers have assumed that such sources are of greatest relevance to the lateral line system (LL). Both hydroacoustic principles and empirical studies have shown that vibratory dipole sources are also a potent stimulus to the inner ear of fishes. Responses to vibratory sources in mottled sculpin (Cottus bairdi) were assessed using unconditioned orienting, differential and non-differential-classical conditioning. Orienting responses are dominated by LL inputs and eliminated by LL pharmacological inactivation. Simple conditioning depends on inputs from other systems and was not affected by LL inactivation. Differential conditioning alters behavioral control, and sculpin could be conditioned to ignore substrate borne vibrations and respond only to hydroacoustic stimulation of the ear. The lateral line and inner ear of mottled sculpin do not necessarily exhibit range fractionation, as both systems operate over a similar distance from the animal (within 1.5 body lengths) and respond to many of the same sources. Vibratory dipole sources generate compound stimuli that simultaneously activate multiple octavolateralis systems, and animals make use of the channels differentially under different behavioral tasks.
