Association of disruption of the caudoventral hippocampal CA1 field with deficits in spatial learning. Panel A shows an H&E stained section from a 3×−chronic exposure rat with a blast-induced lesion in which a portion of the posteromedial cortical amygdaloid nucleus and posteromedial amygdalohippocampal area has been repositioned into the hippocampal CA1 region. Panel B shows performance of this rat (597) in a Morris water maze revealing spatial learning impairments compared to the pooled blast-exposed and control groups (± S.E.M.). Methods and original pooled group data were described in Elder et al. [8]. Scale bar: 200 μm.
