Method for making selective lesions of the hippocampus in macaque monkeys using NMDA and a longitudinal surgical approach

Abstract

We describe a method for making selective lesions of the hippocampus in macaque monkeys, using a magnetic resonance imaging (MRI)‐guided stereotaxic approach in which the excitotoxin N‐methyl‐D‐aspartic acid (NMDA) is injected at intervals along a single needle track that extends longitudinally through the rostrocaudal extent of the hippocampus. Procedures were conducted on six rhesus monkeys (Macaca mulatta) and were assessed with either in vivo MRI (n = 3) or postmortem microscopic examination of the tissue after standard histological processing of the brains (n = 3). Based on our extensive experience with the standard stereotaxic procedure in which ibotenic acid (IBO) is injected via the dorsal approach, we report that the new method provides a viable and potentially advantageous alternative to the standard procedure. First, the longitudinal approach combined with N‐methyl‐D‐aspartic acid (NMDA) injections increases the reliability and efficacy of hippocampal excitotoxic lesions, probably by limiting the leakage of injectant into the ventricles. Second, the present procedure led to more rapid postoperative recovery compared with that after the standard procedure. Third, because the new method requires fewer needle penetrations than the standard method, it most likely reduces the chances of infarction in extrahippocampal tissue. Finally, the new surgical approach may provide a mechanism for infusing agents into the hippocampus from a single cannula. Published 2003 Wiley‐Liss, Inc.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
