Tetrode electrode implantation surgery and data collecting
We used the Self-made movable bundles of the 32-channel tetrode
electrode (Song et al. , 2020) to target the hippocampus CA1 (AP 2
mm; ML 1.8 mm and DV 1.1 mm) of the anesthetized mice on the
stereotactic frame. The local field potentials (LFP) value refers to the
real-time potential under the sampling frequency of 1000 Hz which is
digitized by the Plexon OmniPlex Neural Data Acquisition System (Plexon,
USA), and analyzed by NeuroExplorer Version5.306 (Nex Technologies,
USA).
