Intrinsic optical imaging as well as bioelectrical recordings revealed different patterns of SD propagation in hippocampal and entorhinal slices (Buchheim et al., 2002; Wernsmann et al., 2006). All data indicated of a resistance of the entorhinal cortex for penetration by cortical SD. Although the exact mechanisms responsible for difficulty of cortical SD propagation to the entorhinal cortex are not clear, some hypotheses can be derived from experimental data. A traditional view assumes that the entorhinal cortex faithfully transmits neocortical inputs to the hippocampus and the hippocampus inputs to the neocortex (Naber et al., 1999). More recent evidence suggests that the entorhinal cortex is more than a simple relay between the neocortex and hippocampus. The entorhinal cortices contribute to the gating of impulses between these brain structures. Local inhibition and intrinsic membrane properties of entorhinal neurons are major factors limiting impulse traffic across the entorhinal cortex (Pelletier et al., 2004). Intrinsic optical imaging also revealed different patterns of SD propagation in hippocampal and entorhinal slices (Buchheim et al., 2002). Although the exact mechanisms responsible for different propagation patterns of SD are not clear, some hypotheses can be derived from experimental data. A traditional view assumes that the entorhinal cortices faithfully transmit neocortical inputs to the hippocampus and vice versa (Naber et al., 1999). More recent evidence suggests that the entorhinal cortices are more than a simple relay between the neocortex and hippocampus. Entorhinal cortices contribute to the gating of impulses between these structures. Local inhibition and intrinsic membrane properties of entorhinal neurons are major factors limiting impulse traffic across the entorhinal cortex (Pelletier et al., 2004).
