Figure 4. Morphology of interneurones does not correlate with the short-term plasticity of their inputs.

Paired-pulse ratios obtained from two CA1 s. radiatum interneurones showing different morphological characteristics. A, two biocytin-filled s. radiatum interneurones (interneurones 1 and 2) recorded in the same slice show different morphological characteristics. S. pyramidale is out of the field of view, off the top of the picture. Scale bar, 100 μm. B, paired-pulse ratios are not different at synapses onto interneurone 1 (▪) and interneurone 2 (◯) (P > 0.6).
