Acute cerebellar slices are widely used among neuroscientists to study the properties of excitatory and inhibitory synaptic transmission as well as intracellular signaling pathways involved in their regulation in cerebellum. The cerebellar cortex presents a well-organized circuitry, and several neuronal pathways can be stimulated and recorded reliably in acute cerebellar slices. A widely used acute cerebellar slice preparation technique was adapted from Edwards’ thin slice preparation method published in 1989 (Edwards et al., 1989). Most of the acute cerebellar slice preparation techniques use a vibrating microtome for slicing freshly dissected cerebellum from various animal species. Here we introduce a simpler method, which uses a tissue chopper to quickly prepare acute sagittal cerebellar slices from rodents. Cerebellum is dissected from the whole brain and sliced with a tissue chopper into 200-400 µm thick slices. Slices are allowed to recover in oxygenated aCSF at 37 °C for 1-2 h. Slices can then be used for electrophysiology or other types of experimentation. This method can be used to prepare cerebellar slices from mouse or rat aged from postnatal day 7 to 2 years. The preparation is faster and easier than other methods and provides a more versatile diversity of applications.
