Morphological and Functional Study of the Ultrasonic Effects on the Goldfish Mauthner Cell
The action of ultrasound on morphological and functional states of identified central neurons — Mauthner cells (M-cells) — was investigated. M-cells are the pair of giant neurons in the fish medulla oblongata. They receive the numerous synaptic endings from vestibular apparatus, through acoustic nerve branches(1). M-cells innervate contralateral spinal motoneurones, which in turn govern the tail and body muscles. M-cells play a definite role in the modulation of fishes’ swimming activity, being intercalating neurons in the otolyths-musculature pathway. The latter point of view has been confirmed by numerous experimental data (2,3).
