Auditory Cortex: Complex patterns
• Superior temporal gyrus
• Like other sensory cortex:
– Input layer: IV,
– V: back project to MGB.
– VI: back project to IC
• Some 15 distinct tonotopic
areas (no timing info).
• A1: Primary Auditory Cortex:
logarithmic map of
frequency.
• Perpendicular to freq axis:
– binaural interactions: EE, EI,
– rising or falling pitch
– connections across octaves
