P5.60 Encoding vs retrieval of episodic memory in rats: different theta oscillatory signatures in hippocampo-cortical networks according to individual episodic memory profile

Résumé

A: Posterior piriform cortex raw signal Aquisition through a wireless neural headstage system (TBSI) (sampling rate of 15KHz, bandpass filter 0,8-7000 Hz) B: Time frequency map of corresponding signal Morlet Wavelet Transform and wavelet ridge extraction C: Signal filtered in the 15-40 Hz frequency band and calculated envelope 2,5ms at 0,4 Khz sampling rate D: Behavioral markers Odor is triggered for 10 seconds by the rat nosepoke 3 seconds after the nosepoke, the pipette becomes accessible and the rat has to make a choice (either licking or avoiding) E: Time course of the trial Changes in power envelope are extracted on five 500msperiods (from PRE to POST6) and normalized (ratio) by the same signal extracted on a reference period (REF:-1500 to-1000 ms before the nosepoke)
