Neurons in the Brain Tune into Different Frequencies for Different Spatial Memory Tasks

The findings may provide insight into the cognitive and memory disruptions seen in diseases such as schizophrenia and Alzheimer's.

Place cells in the hippocampus provide a neuronal code for specific locations in space. Place cells codes represent upcoming locations at some times and reflect recently visited locations at other times. The findings by Bieri and colleagues show that place cells predict upcoming locations during periods of slow gamma rhythms and encode recently visited locations during periods of fast gamma rhythms.
