Dearworth Jr J, Granda A
J Vis . 2003 Apr; 2(3):204-17. PMID: 12678583
Retinal ganglion cells in the turtle were extracellularly recorded to define the shapes of their receptive fields by small moving light spots. To better define the geometries, spectral-light adaptations and...

Granda A, Dearworth Jr J, Subramaniam B
Vis Neurosci . 1999 Jun; 16(2):319-32. PMID: 10367966
Receptive fields of retinal ganglion cells in turtle have excitatory and inhibitory components that are balanced along the dimensions of wavelength, functional ON and OFF responses, and spatial assignments of...

Granda A, Dearworth Jr J, Kittila C, Boyd W
Vis Neurosci . 1995 Nov; 12(6):1127-33. PMID: 8962831
When intense adapting lights are turned off, the pupil of the turtle, Pseudemys scripta elegans, enlarges. The recovery functions for pupillary dilation have different time constants that are defined by...

Kittila C, Granda A
J Comp Neurol . 1994 Dec; 350(4):623-45. PMID: 7890834
Retinal ganglion cells in the turtle, Pseudemys scripta elegans, were examined by intracellular recording with a protocol of stationary and moving lights. Responses were apportioned among OFF, ON, and ON-OFF...
5.
Northmore D, Granda A
Vis Neurosci . 1991 Dec; 7(6):627-35. PMID: 1772809
Measurements were made of the ocular dimensions from living and frozen eyes of one species of freshwater turtle, Pseudemys scripta elegans, and of three species of marine turtles, Chelonia mydas,...

Northmore D, Granda A
Vis Neurosci . 1991 Dec; 7(6):619-25. PMID: 1772808
Visual-evoked potentials (VEPs) were recorded from the surface of the optic tectum of the freshwater turtle, Pseudemys scripta elegans, in response to phase reversal of square-wave gratings of different spatial...
7.
Dvorak C, Granda A
Vis Neurosci . 1990 May; 4(5):427-35. PMID: 2271453
Electrical responses of luminosity horizontal cells (L cells) to monochromatic stimuli were analyzed by intracellular recordings in the retinas of the freshwater turtle (Pseudemys scripta elegans) and of the sea...

Granda A, Fulbrook J
J Neurophysiol . 1989 Sep; 62(3):723-37. PMID: 2769356
1. Receptive fields of 78 retinal ganglion cells were analyzed for their responses to moving and stationary lights that were presented under a variety of stimulus conditions. All cells were...

Granda A, Sisson D
Vision Res . 1989 Jan; 29(1):93-105. PMID: 2773338
Two-color increment thresholds were measured in turtle using a behavioral avoidance paradigm. Four visual mechanisms were isolated, and their spectral sensitivities were compared to action spectra of photoreceptors known to...

Sisson D, Granda A
Vision Res . 1989 Jan; 29(1):107-14. PMID: 2773328
Visual mechanisms isolated in Pseudemys by the two-color threshold technique of Stiles show peak wavelength sensitivities at 650 nm (red light) and 540 nm (green light). Ricco critical areas were...
