Memory integration constructs maps of space, time, and concepts

Memory integration constructs maps of space, time, and concepts.

Recent evidence demonstrates that new events are learned in the context of their relationships to existing memories. Within the hippocampus and medial prefrontal cortex, related memories are represented by integrated codes that connect events experienced at different times and places. Integrated codes form the basis of spatial, temporal, and conceptual maps of experience. These maps represent i...

Time regained: how the human brain constructs memory for time

Life’s episodes unfold against a context that changes with time. Recent neuroimaging studies have revealed significant findings about how specific areas of the human brain may support the representation of temporal information in memory. A consistent theme in these studies is that the hippocampus appears to play a central role in representing temporal context, as operationalized in neuroimaging...

Human intracranial high-frequency activity maps episodic memory formation in space and time

Noninvasive neuroimaging studies have revealed a network of brain regions that activate during human memory encoding; however, the relative timing of such activations remains unknown. Here we used intracranially recorded high-frequency activity (HFA) to first identify regions that activate during successful encoding. Then, we leveraged the high-temporal precision of HFA to investigate the timin...

Multisensory Integration: Space, Time and Superadditivity

The superior colliculus generates and controls eye and head movements based on signals from different senses. The latest research on this structure enhances our understanding of the mechanisms of multisensory integration in the brain.
