Theta synchronization coordinates ventral temporal and medial temporal coding of human face familiarity.

Theta synchronization between ventral temporal cortex and medial temporal lobe is crucial for encoding face familiarity in humans, with a significant role in neural coordination.

• Why it matters: Understanding how the brain recognizes familiar faces is essential for social cognition, yet the neural mechanisms linking perceptual and memory systems are not well understood.
• What they did: The study used single-neuron recordings, intracranial EEG, and connectivity analyses in Homo sapiens to examine neural dynamics, focusing on theta-frequency phase locking related to face familiarity.
• The result: Findings show that theta synchronization enhances between visual-feature and familiarity-coding channels, enabling coordinated neural responses that underpin face recognition and familiarity processing.
