我们已经确定了13对神经元的海洋裸鳃海蛞蝓Tritonia diomedea的足神经节的张力和/或相位响应水流直接在鞘和口面纱提示。大多数神经元对来自身体两侧的输入的反应相同，但6对对同侧水流刺激的反应强度更大。当在半完整的整个动物制备物中进行细胞内刺激时，这6对神经元中的4对引起同侧运动，可能使动物转向该侧。这些观察结果表明，这些电流敏感神经元在先前描述的方向，水流inTritonia diomedea的作用。
We have identified 13 pairs of neurons in the pedal ganglia of the marine nudibranch slugTritonia diomedeathat responded tonically and/or phasically to water-flow directed at the rhinophore sheaths and oral veil tips. Most of the neurons responded equally to inputs from either side of the body, but 6 pairs responded with greater intensity to ipsilateral water-flow stimuli. When stimulated intracellularly in a semi-intact, whole-animal preparation, 4 of these 6 pairs of neurons caused ipsilateral movements that may turn the animal towards that side. These observations suggest a role for these current-sensitive neurons in the previously described orientation to water-currents inTritonia diomedea.
