Approximately 36% of the complex spike cells in CA1 (range 26–62%) and 26% of the complex spike cells in CA3 (range 22–33%) had place fields in the first standard session of the day; other ...

Hippocampal CA3–CA1 regions were dissected from 1- to 3-day-old Sprague-Dawley rats, triturated and plated on glass-bottomed microwell dishes 10–15 days before use.

Noncanonical projections to the hippocampal CA3 regulate spatial learning and memory by modulating the feedforward hippocampal trisynaptic pathway. PLOS Biology , 2021; 19 (12): e3001127 DOI: 10. ...

A research team led by University of California, Irvine has discovered new neural circuits that regulate spatial learning and memory in the brain’s hippocampal formation. The team identified novel ...

Lin, X., et al. (2021) Non-canonical projections to the hippocampal CA3 regulate spatial learning and memory by modulating the feedforward hippocampal trisynaptic pathway. PLOS Biology . doi.org ...

Neurons in the CA3 subregion extend projections bilaterally into the CA1 area. Cells in the left CA3, for example, relay information to neurons in the left and right CA1, and cells in the right CA3 do ...

The study, “A Hippocampal Circuit Mechanism to Balance Memory Reactivation During Sleep,” published Aug. 15 in Science, reports that at certain times during deep sleep, certain parts of the ...
