WebDec 16, 2024 · What type of cell is the eye? 1. Photoreceptors There are two main types of light-sensitive cell in the eye: rods and cones. Rods enable vision in poor light, whereas cones are responsible for colour vision. Photoreceptors convert light into electrical signals that travel through other retinal neurons to reach the optic nerve. WebEye Cells Are Out of Sight. A new study sheds light on how a particular kind of cell in the eye—crucial for light-related functions other than seeing—detects light and communicates with the brain. A better …

The first responds the most to light of the longer red wavelengths, peaking at about 560 nm. The majority of the human cones are of the long type. The second most common type responds the most to light of yellow to green medium-wavelength, peaking at 530 nm. …
WebKhazali et al. introduce a novel network analysis that extracts shared excitability from recordings of local field potentials distributed across different brain regions. The results suggest that shared excitability in the posterior parietal cortex correlates with the motor control of coordinated eye-hand movements and interacts with specific neuronal cell types.
