NF regulation of intracellular Ca²⁺ transients. a Representative [Ca²⁺]_i transients in NT and NF. b Mean values of [Ca²⁺]_i transient parameters. NF significantly increased diastolic [Ca²⁺]_i and peak amplitude of [Ca²⁺]_i. Time to 50 % relaxation and peak time duration (PT₉₀ + TR₁₀) were prolonged; however, time constant of [Ca²⁺]_i decay (tau) was facilitated in NF
