Figure Lengend Snippet: DNE alters the modulation of glutamatergic sEPSCs in response to an acute nicotine challenge but only in cells from pups aged P3–P5. Cumulative probability distributions of glutamatergic sEPSC IEIs in control and DNE cells, at baseline and during acute nicotine challenge. At P1–P2 ( A , B ), acute nicotine challenge with 0.5 μM nicotine (black dashed lines) caused a left shift, toward shorter IEIs, of glutamatergic sEPSCs in both control and DNE cells [control, p = 0.049 ( A ) DNE, p < 0.0001 ( B )]. In cells from P3–P5 animals ( C , D ), acute nicotine challenge caused a left shift, toward shorter IEIs in control cells ( p < 0.0001; C ), but the distribution shifted to the right, toward longer IEIs in the DNE cells ( p = 0.012; D ). Arrows indicate the direction of the shift with acute nicotine challenge and indicates significant differences with K–S test (see Materials and Methods). Dotted gray lines indicate the 95% confidence intervals of each curve.
