To understand the natural discharge pattern of neurons, plasticity and resonance, our in-vivo electrophysiological recordings are mainly made in CrusIIa of Cerebellum.

In-vivo stimulation is performed by a Theta Sensory Stimulation (TSS), using an air-puff on the rat whiskerpad.

In some cases also an electrical stimulation can be perfomed into the cerebellum

 In-vivo techniques used are the following:

  • field recordings (single electtrode);
  • patch-clamp recordings (whole-cell and cell-attached configurations);
  • MEA recordings (see below)
