Cochlea
The cochlea is the part of the inner ear involved in hearing. It is a spiral-shaped cavity in the bony labyrinth, in humans making 2.75 turns around its axis, the modiolus. A core component of the cochlea is the Organ of Corti, the sensory organ of hearing, which is distributed along the partition separating the fluid chambers in the coiled tapered tube of the cochlea. The name cochlea derives . The cochlea (: cochleae) is a spiraled, hollow, conical chamber of bone, in which waves propagate from the base (near the middle ear and the oval window) to the apex (the top or center of the spiral).
Localisation sonore
vignette|Localisation sonore avec des indices binauraux (une oreille capte plus de son que l'autre). La localisation sonore désigne la capacité du système auditif à déterminer la position spatiale d'une source sonore au moyen de différents indices physiques. Ces indices peuvent être classés en deux catégories : les indices binauraux (c'est-à-dire issus de l'analyse combinée des sons parvenant aux deux oreilles) et des indices monauraux (c'est-à-dire ceux que l'on peut déterminer avec une seule oreille).
Stimulus modality
Stimulus modality, also called sensory modality, is one aspect of a stimulus or what is perceived after a stimulus. For example, the temperature modality is registered after heat or cold stimulate a receptor. Some sensory modalities include: light, sound, temperature, taste, pressure, and smell. The type and location of the sensory receptor activated by the stimulus plays the primary role in coding the sensation. All sensory modalities work together to heighten stimuli sensation when necessary.
