The response in neurons and astrocytes on K⁺ stimulation is modified after TeNT treatment.A, Kinetics of the [Ca²⁺]_i changes in two representative neurons (continuous lines) and astrocytes (dotted lines) from the visual cortex of a 10-d-old rat in response to stimulation with 60 mm KCl after slice incubation with TeNT. B, Mean values ± SE of the change in R405:485 representing the amplitude of [Ca²⁺]_i elevations on K⁺ stimulation in neurons (N) and astrocytes (A) from control slices (42 neurons and 27 astrocytes, 6 experiments) and TeNT-treated slices (63 neurons and 37 astrocytes, 6 experiments). *p < 0.001.
