We performed electrophysiological recording using an HS-36 headstage amplifier, the Digital Lynx SX data acquisition system and Cheetah Software 5.7.0 (Neuralynx, Inc., MT, USA). Electrical signal was band-pass filtered at 0.1–9000 Hz for each channel of the electrode. For spike sorting, we used an automated clustering algorithm in klusta software (Rossant et al., 2016). We then manually curated the results using Kwik-gui (https://github.com/cortex-lab/phy/ ). For analysing sharp-wave ripples, we used Neuralynx CSC filtering tools (Neuralynx, Inc., MT, USA) to apply a band-pass filter of 150–250 Hz to LFP.

The Digital Lynx SX is a high-performance data acquisition system designed for neuroscience research. It is capable of recording neural signals with high precision and reliability. The core function of the Digital Lynx SX is to capture and digitize electrophysiological data from multiple channels simultaneously.

Throughout each maze session, a 128 channel DigitalLynx SX data acquisition system (Neuralynx, Bozeman, MT) was used to record LFP signals and single units at a sampling rate of 32 kHz per channel. LFP channels were high pass filtered above 1 Hz, and single‐unit channels were bandpass filtered between 600 and 6000 Hz. Recording sessions varied in duration from 45 min to 2 h. At the end of a recording session, the rat occupied the bucket for 5 min before disconnection from the recording system. Tetrodes in LS and striatum were advanced by 333 μm after each session, so that different units would be recorded from these tetrodes in every session. By contrast, hippocampal tetrodes were advanced by at most 83 μm/day (and usually not at all), so that these tetrodes would remain within the hippocampal region throughout the entire experiment. Rats remained in the experiment area and rested in their home cages for at least 1 h before being returned to the vivarium for weighing and feeding.
About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
