| state-related discharge of neurons in the brainstem of freely moving box turtles, terrapene carolina major. | we have performed the first study of neuronal activity in freely-moving reptiles. 23 brainstem units were recorded from areas throughout the reticular formation, during wakefulness and quiescence in the box turtle. these units responded to various sensory stimuli and increased firing rates in relation to motor activity during wakefulness. all but one unit showed significant decreases in discharge during quiescence. group i cells (32%) fired mostly during active movements and exhibited silent per ... | 2001 | 11256184 |
| evidence for auditory localization ability in the turtle. | evidence is presented that the semiaquatic turtle chrysemys scripta and the terrestrial turtle terrapene carolina major can detect the direction of a tone within their sensitive area of hearing. it is further suggested that not only can these species respond behaviorally to sound without extensive manipulation but can use limited hearing in a problem-solving situation of maze learning. adult emydid turtles (5 c. scripta, 3 t. carolina) learned a y-maze with a 500-c/s signal to an invisible open ... | 1981 | 7186502 |
| use of rocuronium for endotracheal intubation of north american gulf coast box turtles. | to determine whether rocuronium, a reversible neuromuscular blocking agent, would provide safe, short-term immobilization to facilitate endotracheal intubation in turtles. | 2003 | 12710776 |
