For more than a century now, it has been known that patterns of electrical activity between neurons account for the marvelous repertoire of animal behaviors that we see in nature. Neuroethology tries to understand how the nervous system is responsible for animal behavior. The marine nudibranch Tritonia diomedea possesses a rather simple nervous system with maybe ten thousand brain cells (compared to the one hundred billion estimated for Homo sapiens). This book focuses on the very important role of a single pair of neurons in the motor behavior of this sea slug. The techniques used allowed for the recording and the stimulation of individual cells during navigation in the freely moving animal. The analysis revealed a sufficient role for a pair of neurons in turning while crawling suggesting that Tritonia’s nervous system integrates sensory information into a single cell capable of directing the motor output during crawling. This work reveals the capabilities of a single cell in behavor...
