Figure 8

Showing stimulus intensity-network response functional curves in the hippocampal formation of naïve, saline (Sal-control) and bee venom (BV)-inflamed rats. A, an example showing that individual field excitatory postsynaptic potential in either the dentate gyrus (DG) (upper) or the CA1 (lower) area was increased in amplitude (B) or slope (C) in an intensity-dependent manner. The input-output functional curves of the DG (upper) and CA1 (lower) network response were leftward shifted in the BV-inflamed rats to those of naïve and Sal-control rats. Vertical scale in A indicates amplitude of the potentials, while horizontal scale indicates time sweep. The number of slices for each group is shown in parentheses. Error bars: ± S.E.M.
