Definitions:

Transduces Light

refers to the conversion of light into another form of energy, such as in the process of vision in the eyes where photoreceptor cells transduce light signals into neural signals.

Neural Impulses

Electrical signals transmitted along the neurons of the nervous system, facilitating communication between the brain and various parts of the body.

Spectral Sensitivity

The responsiveness of a sensory system to various wavelengths of light, often used in describing visual perception.

Rod Vision

Rod vision refers to the aspect of vision that allows living organisms to see in low light conditions, enabled by rod cells in the retina that are more light-sensitive than cone cells.
