Abstract
AbstractBehavioral neuroscience has long relied on in vivo electrophysiology to provide spatially and temporally precise answers to complex questions about the neural dynamics underlying sensory processing and action execution. Investigating the neural correlates of behavior can be challenging in freely behaving animals, especially when making inferences related to internal states that are temporally or conceptually ambiguous, such as decision‐making or motivation. This necessitates careful creation of appropriate and rigorous controls and awareness of the many potential confounds when attributing neural signals to animal behavior. This article discusses fundamental considerations for the optimal design and interpretation of in vivo rodent electrophysiological recording experiments and focuses on the different optimization strategies required when investigating neural encoding of external stimuli versus free behavior. The first protocol offers suggestions specific to intracranial surgical implantation of multielectrode arrays. The second protocol delves into optimization strategies and tips useful for designing and interpreting recording experiments conducted in freely behaving rodents. © 2023 Wiley Periodicals LLC.Basic Protocol 1: Surgical implantation of the multielectrode arrayBasic Protocol 2: Optimizing experimental design and parameters
