新的感官体验，特别是那些与划时代的发展事件，如护理改变皮层代表，影响记忆，感知和行为。功能磁共振成像在这里被用来测试是否在哺乳期间修改的感觉皮质地图的腹。三种刺激被用来驱动皮质激活的分娩大鼠：自然，人工吸吮刺激和一般机械摩擦的腹侧皮肤。这些刺激显着激活了母鼠的躯体感觉皮层。在这三种刺激中，人工哺乳和幼犬哺乳强烈激活了大脑的大部分区域，最明显的是视觉、听觉和嗅觉皮层。令人惊讶的是，即使在没有幼崽的情况下，在人工哺乳的情况下也会发生激活。这一发现表明，来自单一模态的传入信息足以驱动其他模态的活动。在哺乳过程中，整个皮层地幔的敏感性增强，可能有助于母鼠感知、处理和记住对照顾和保护幼鼠至关重要的刺激。爱思唯尔公司出版
Novel sensory experiences, particularly those associated with epochal developmental events like nursing alter cortical representation, affecting memory, perception and behavior. Functional MRI was used here to test whether the sensoricortical map of the ventrum is modified during lactation. Three stimuli were used to drive cortical activation in primiparous rats: natural, artificial suckling stimulation and general mechanical rubbing of the skin of the ventrum. These stimuli significantly activated the somatosensory cortex of dams. Of the three stimuli, artificial and pup suckling robustly activated much of the cerebrum, most notably the visual, auditory and olfactory cortices. Surprisingly, activation occurred even in the absence of pups, with artificial suckling. This finding suggests that incoming information from a single modality was sufficient to drive activity of others. Enhanced sensitivity across the cortical mantle during nursing may help the dam to perceive, process, and remember stimuli critical to the care and protection of her young. Published by Elsevier Inc.
