Basilar Membrane

The basilar membrane is a key structure in the cochlea of the inner ear, playing a crucial role in the process of auditory transduction by vibrating in response to sound and facilitating hearing.

Place Theory

A theory explaining how the inner ear registers the frequency of sounds, based on the location along the cochlea’s basilar membrane that sound waves peak.

Cones

Visual receptors that respond to greater light intensities and give rise to chromatic (color) sensations.

Visual Sensations

The experience derived from light stimulating the visual receptors in the eyes, leading to visual perception.
