Auditory cortex
Auditory Cortex
The Auditory Cortex (pronounced: aw-dit-or-ee kor-teks) is the part of the temporal lobe that processes auditory information in humans and many other vertebrates. It is a part of the auditory system, which enables organisms to convert acoustic signals into meaningful information.
Etymology
The term "Auditory Cortex" is derived from the Latin words "audire", meaning "to hear", and "cortex", meaning "bark" or "rind". This is in reference to its role in processing sound and its location in the outer layer of the brain.
Function
The Auditory Cortex is responsible for the perception of sound, pitch, and loudness. It also plays a role in the localization of sound sources in the environment and the identification of voices. The Auditory Cortex is divided into two main areas: the primary auditory cortex (A1) and the secondary auditory cortex (A2). The primary auditory cortex is the first region of the cortex to receive auditory input from the thalamus, while the secondary auditory cortex is involved in the interpretation of the complex features of sound.
