phototransduction
Visual phototransduction is the sensory transduction of the visual system
aerial perspective
Aerial perspective or atmospheric perspective refers to the effect the atmosphere has on the appearance of an object as it is viewed from a distance
decibel
The decibel is a logarithmic unit used to express the ratio of two values of a physical quantity
somatosensory system
The somatosensory system is a complex system of nerve cells that responds to changes to the surface or internal state of the body
Gustav Fechner
Gustav Theodor Fechner , was a German philosopher, physicist and experimental psychologist
optic nerve
The optic nerve, also known as cranial nerve II, is a paired nerve that transmits visual information from the retina to the brain
photoreceptors
A photoreceptor cell is a specialized type of neuron found in the retina that is capable of phototransduction
eardrum
In human anatomy, the eardrum, or tympanic membrane, is a thin, cone-shaped membrane that separates the external ear from the middle ear in humans and other tetrapods
ossicles
The ossicles are three bones in either middle ear that are among the smallest bones in the human body
pressure
Pressure is the force applied perpendicular to the surface of an object per unit area over which that force is distributed
fovea
The fovea centralis is a small, central pit composed of closely packed cones in the eye
