Hippocampal CA2 Organizes CA1 Gamma Oscillations During Investigation of Novel Stimuli
Jun 11, 2020
Material below summarizes the article Hippocampal CA2 Organizes CA1 Slow and Fast γ Oscillations during Novel Social and Object Interaction, published on March 20, 2020, in eNeuro and authored by Logan Y. Brown, Georgia M. Alexander, Jesse Cushman, and Serena M. Dudek.
Highlights
- CA2 contributes to slow gamma oscillations in CA1 during novel animal investigation and fast gamma during novel animal or novel object investigation.
- Chemogenetic inhibition of CA2 neurons causes a decrease in slow gamma oscillations in the pyramidal cell layer of CA1 selectively during novel animal investigation.
- Chemogenetic inhibition of CA2 causes a layer-specific decrease in CA1 gamma power reflective of CA2’s anatomical inputs to CA1.
