a) Localization of microelectrodes in the mPFC of animals aged PND 28–38, PND 44–55 and adult animals according to Paxinos and Watson brain atlas, fourth edition [24]. PL: prelimbic, IL: infralimbic, fmi: forceps minor. b) Photomicrograph illustrating a representative placement of the microelectrode in the mPFC of a PND38 rat, (coronal section). The end of the platinum tip of the microelectrode (i.e. the recording sites) is indicated by the arrow.
