Study examined the expression of M1 muscarinic ACh receptors in the hippocampus at 7 and 30 days following experimental bilateral vestibular lesions (BVL) in rats using autoradiography. Analysis of the brain tissue revealed a significant reduction in the number of M1 receptors throughout the hippocampus and striatum at 30 days but not at 7 days following BVL.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
