Concurrent recordings of hippocampal neuronal spikes and prefrontal synaptic inputs from an awake rat

STAR Protoc. 2021 Jun 8;2(2):100572. doi: 10.1016/j.xpro.2021.100572. eCollection 2021 Jun 18.


A major challenge in neuroscience is linking synapses to cognition and behavior. Here, we developed an experimental technique to concurrently conduct a whole-cell recording of a prefrontal neuron and a multiunit recording of hippocampal neurons from an awake rat. This protocol includes surgical steps to establish a cranial window and 3D printer-based devices to hold the rat. The data sets allow us to directly compare how subthreshold synaptic transmission is associated with suprathreshold spike patterns of neuronal ensembles. For complete details on the use and execution of this protocol, please refer to Nishimura et al. (2021).
