But before the Indo-Europeans there were likely other waves of migrants bringing their own culture, foremost among them the Neolithic farmers.
Unless, of course, the Neolithic farmers were the Indo-Europeans, following Renfrew et al. In which case Basque is either earlier or a separate later incursion. As I understand it, the few inscriptions associated with the Aquitani (one of the three parts into which Caesar recognised that geographical Gaul was divided) appear to be related to Basque, which suggests they were at one time more widespread.
Impedance -based single cell analysis systems are commonly known as Coulter counters . They represent a well-established method for counting and sizing virtually any kind of cells and particles. The label-free technology has recently been enhanced by a " lab-on-a-chip " based approach and by applying high frequency alternating current (AC) in the radio frequency range (from 100 kHz to 30 MHz) instead of a static direct current (DC) or low frequency AC field.  This patented technology allows a highly accurate cell analysis and provides additional information like membrane capacitance and viability . The relatively small size and robustness allow battery powered on-site use in the field.
