Behavioral responses

• Behavioral responses
• Threshold of hearing (peripheral system degradation with age)
• Alerting (Auditory evoked response- Startle)
• MIND signaling to awakening
• Middle ear reflex response
• Neck reflex (Tectospinal ) turn to see sound source or position head for better detection of direction. Inferior colliculus has a spatial map for directional turning of the head.
• Otoacoustic Emissions- Clinical phenomenon
• Sound appreciation
• Direction of source- Biaural system response
• Complex sound discrimination- Efferent system
• Tonotopic organization and cortical integration of sound
