Abstract
Optical methods for monitoring changes in membrane potential have been used to measure action potential activity in the buccal ganglion of an opisthobranch mollusc, Navanax inermis, while the animal was feeding. During feeding activity was detected in 10-15% of the approximately 200 neurons present in the ganglion. Control experiments carried out to determine the completeness of the optical recording showed that activity in at least 70% of the neurons could be detected. Thus, in certain invertebrate ganglia, it is possible to make a reasonably complete recording of the neuron activity responsible for generating relatively complex behaviors.
摘要
光学方法用于监测膜电位变化，已被用于测量裸鳃亚目软体动物无沟海牛在进食时口腔神经节中的动作电位活动。在进食过程中，在神经节中大约200个神经元中的10%-15%检测到了活动。为确定光学记录的完整性而进行的对照实验表明，至少70%的神经元活动可以被检测到。因此，在某些无脊椎动物神经节中，有可能对负责产生相对复杂行为的神经元活动进行合理完整的记录。
