a Microplate readings of HN1 and AD constructs with microspheres (CM) and constructs (C) all at rest. All groups n = 3 and statistics completed with one-way student t-test, * shows significance between resting membrane potential on days 30 and 45. Microplate readings of all bioprinted constructs membrane potentials measured at rest and excited with Ach on day 30 (b) and day 45 (c) of culture. And bioprinted constructs membrane potentials measured at rest and excited with KCL on day 30 (d) and day 45 (e) of culture. All groups of n = 3 and statistics completed with one-way paired student t-test, * shows significance between at rest and excited readings
