Memory stretches over a lifetime. In controlled laboratory settings, the hippocampus and other medial temporal lobe brain structures have been shown to represent space and time on the scale of meters and seconds. It remains unclear whether these regions also represent space and time over the longer scales necessary to support human episodic memory. In this talk I will review our recent work to uncover the neural representation of both objective (space and time) and subjective (context tags provided by the participant) details of real-life remembered experiences via lifelogging and functional neuroimaging. Participants wore android phones equipped with custom lifelogging software to collect data about their everyday events for a period of 2 to 4 weeks. They then relived episodes from their own lives, cued by images collected with the lifelogging device. Similarity-based analyses revealed specific networks of brain regions, including the hippocampus, that track the objective and subjective details of remembered experiences. These regions and representations may provide a scaffold for encoding and retrieval of autobiographical memories on the scale of our lives.
