Preparation of acute living hippocampal slice from common marmoset (Callithrix jacchus) for synaptic function analysis.

We described the preparation of acute living slices from the hippocampus of the neonatal common marmoset (Callithrix jacchus). Slices from a temporal lobe section were prepared quickly using a rotary slicer. By this method, we successfully recorded field potentials, namely, pre-synaptic fiber volley and field excitatory post-synaptic potentials, from the hippocampal CA1 region with conventional electrophysiological techniques, and analyzed the indicators of synaptic function such as input-output curve. This study thus presents an efficient preparation method for acute living hippocampal slice from which synaptic function of the hippocampus in non-human primate can be analyzed.
