The hundredfold or more higher resolution of the electron microscope (EM) clearly offers promise of distinct adv...

sensitivity curve for 1° 200 ms. flashes on a white background may be a rather precise indicator of the functioning of the opponent-color system. Thus, although J. T. believed that his right eye was normal, the corresponding spectral sensitivity curve (continuous curve, Fig. 3) lies near the limit of the normal range, indicating that his right eye may have been partially affected by a similar d...

Cortical Evolution: Introduction to the Reptilian Cortex

Some 320 million years ago (MYA), the evolution of a protective membrane surrounding the embryo, the amnion, enabled vertebrates to develop outside water and thus invade new terrestrial niches. These amniotes were the ancestors of today’s mammals and sauropsids (reptiles and birds). Present-day reptiles are a diverse group of more than 10,000 species that comprise the sphenodon, lizards, snakes...

Reptilian Eyes and Orbital Structures

The anatomy of the reptilian eye is similar across species, generally, but the eyes of various taxa differ in details. The eyeball is formed of layers and has three chambers. Pupil shape differs among reptilian taxa with behavior. The retina’s photosensitive cells (rods and cones or allcones) transmit signals to the optic nerve, which is an extension of the brain. Retinal sensitivity is increas...
