Hippocampal maps predict context-dependent behavior — ScienceDaily

Successful navigation requires the ability to separate memories in a context-dependent manner. For example, to find lost keys, one must first remember whether the keys were left in the kitchen or the office. How does the human brain retrieve the contextual memories that drive behavior? J.B. Julian of the Princeton Neuroscience Institute at Princeton University, USA, and Christian F. Doeller of the Max Planck Institute for Human Cognitive and Brain Sciences in Leipzig, Germany, found in a recent study that modulation of map-like representations in our brain’s hippocampal formation can predict contextual memory retrieval in an ambiguous environment.

The researchers developed a novel virtual reality navigation task in which human participants learned object positions in two different virtual environments and then had their memory tested during a functional…
