Bilateral electrolytic lesions of the dorsal hippocampus of white rats were shown to facilitate elaboration of a conditioned response of active avoidance of pain shock in a shuttle-box. The lesions of the ventral hippocampus had no effect on conditioning. The ventral hippocampal lesions led to a complete failure to form differential inhibition. In rats with the dorsal hippocampal lesions an acquisition of partial (up to 60 per cent) discrimination of stimuli was possible. The differences in avoidance conditioning and elaboration of differential inhibition in rats with the dorsal and ventral hippocampal lesions are supposed to be caused by the changes of general excitability and emotional state of animals as well as by a specific role of the ventral hippocampus in memory consolidation.
实验表明，对白鼠双侧背侧海马进行电解损伤，有助于在穿梭箱中建立主动回避疼痛电击的条件反应。腹侧海马损伤对条件作用没有影响。腹侧海马损伤导致完全无法形成分化抑制。在背侧海马损伤的大鼠中，有可能获得部分（高达60%）的刺激辨别能力。背侧和腹侧海马损伤的大鼠在回避条件作用和分化抑制形成方面的差异，被认为是由动物的一般兴奋性和情绪状态的变化以及腹侧海马在记忆巩固中的特定作用引起的。
