This syringe was carefully inserted into the hippocampus with the following coordinates: 5.2 mm posterior, 4.3 mm lateral, 4.8 mm deep (relative to Bregma). CSF samples from four anti-NMDAR encephalitis patients and three control patients. Methods: We performed a stereotactic injection of patient-derived cell-free CSF with confirmed presence or absence of NMDAR-antibodies into the rat hippocampus = 54) was significantly higher than LTP in slices from NMDAR-CSF-treated animals (139 9%, = 40; = 0.015), although there was some variation between the individual CSF samples. We found residual LTP in NMDAR-CSF-treated tissue which could be abolished (S,R,S)-AHPC hydrochloride by the NMDAR inhibitor D-AP5. Moreover, the CA3 field excitatory postsynaptic potential (fEPSP) was followed by epileptiform afterpotentials in 5% of slices (4/78) from control-CSF-treated animals, but in 26% of slices (12/46) from…
