Forskolin and cBIMPS occlude activity-dependent LTP in burst firing neurons. A, C, In bursting cells forskolin-induced enhancement of EPSCs prevented tetanus-induced LTP (1.07 ± 0.13, n = 6). B, D, Sp-5,6-DCl-cBIMPS mimicked and occluded tetanus-induced LTP in bursting neurons (1.23 ± 0.09, n = 5). E, In forskolin-preincubated slices, regular firing but not bursting cells express activity-dependent LTP upon tetanic stimulation (1.76 ± 0.31, n = 6). F, Blockade of PKA by Rp-8-CPT-cAMP prevented LTP in bursting neurons (1.14 ± 0.10, n = 6).
