An electrophysiological study of the photo-excitative neurones of Onchidium verruculatum in situ.
The giant neurones and relatively long nerves or connectives of the mollusca have been used extensively in electrophysiological studies, but little work has been done on the physiological behaviour of neurones in situ. Hughes & Tauc (1962) have reported investigation on giant cells of Aplysia in the whole animal as well as in isolated ganglion preparations. Recently, the gill-withdrawal reflex ...
متن کاملPhotosensitive neurones in the marine pulmonate mollusc Onchidium verruculatum.
It has been amply demonstrated that the nerve cells of some animals respond to light, and that excitatory and inhibitory cells are involved in this response (Arvanitaki & Chalazonitis, 1949a, b, 1958; Kennedy, 1961, 1963; Yoshida & Millott, 1959). In the photo-excitative cell, depolarization of the membrane, appearance of spikes or increase of their frequency have been seen in response to light...
متن کاملA Neural Mechanism for Processing Colour Information in Molluscan Extra-ocular Photoreceptors
This study was conducted to clarify the electrical and spectral properties of the combined photoresponses of two extra-ocular photoreceptor neurones, A-P-l and Es-1, in the abdominal ganglion of the marine mollusc Onchidium verruculatum. The depolarizing receptor potential or inward receptor current of Es-1 appeared to result from a decrease in K conductance, in the same way as in A-P-l. The di...
متن کاملIdentification of neuronal connections in the central nervous system of Onchidium verruculatum.
It is important for the study of information processing in the nervous system to know neuronal connections as well as characteristics of neural signals conveyed by its elements. Neuronal connections in the abdominal ganglion of Aplysia have been studied by many authors1-8). Some of them1,4-8) recorded simultaneously spontaneous activity of two or more neurons with intracellular electrodes and i...
متن کاملIntegrative taxonomy of the genus Onchidium Buchannan, 1800 (Mollusca, Gastropoda, Pulmonata, Onchidiidae)
In an effort to clarify the species diversity of onchidiid slugs, the taxonomy of the genus Onchidium Buchannan, 1800 is revised using an integrative approach. New, fresh specimens were collected in a large number of places, including type localities. The genus Onchidium is redefined here as a clade including only three species which are strongly supported by both morphological and molecular da...
