Infusão estereotáxica de oligomica beta-amilóide no ratinho Hippocampus

Overview

This article presents a protocol for direct stereotaxic brain infusion of amyloid-beta, specifically Liga meric a beta 1 42, into the dentate gyrus of the hippocampus. This methodology provides an alternative in vivo mouse model to investigate the short-term effects of amyloid-beta on brain neurons.
