Abstract

Respirometry is a technique for studying mitochondrial function that has proven compatibility with ≥0.5 mg of brain tissue. Here, we present a protocol for assessing oxygen consumption and H <subscript>2</subscript> O <subscript>2</subscript> production rates in hippocampal tissue using the Oroboros O2k system. We describe steps for brain harvesting, tissue preparation, hippocampal microdissection, and respirometry assays. This approach has been valuable to study the metabolism of dentate granule cells of the hippocampus and could be applicable to other brain subregions. For complete details on the use and execution of this protocol, please refer to Rose et al. <superscript>1</superscript> .<br />Competing Interests: Declaration of interests The authors declare no competing interests.<br /> (Copyright © 2024 The Author(s).
