The effects of cooling on electrical responses of goldfish ( Carassius auratus) central nervous system

1. 1. Various components of the cerebellar field potential response to parallel fibre stimulation from 25°C-acclimated goldfish block at 8–9°C. Synaptic excitation of Purkinje cells is most sensitive. 2. 2. Antidromic Purkinje responses, and responses to mossy fibre and climbing fibre stimulation, w...

Beschreibung
Zusammenfassung:	1. 1. Various components of the cerebellar field potential response to parallel fibre stimulation from 25°C-acclimated goldfish block at 8–9°C. Synaptic excitation of Purkinje cells is most sensitive. 2. 2. Antidromic Purkinje responses, and responses to mossy fibre and climbing fibre stimulation, were more resistant to cooling than were responses to parallel fibre stimulation. 3. 3. The cerebellar field potential resulting from optic nerve stimulation blocked at 8°C. Acclimation to 15 and 5°C increased the cold resistance of this response. 4. 4. Tactile responses of goldfish facial lobe blocked after cooling to 6°C.
