- The nerve cells in the prefrontal cortex of fathers had more tiny projections, known as dendritic spines, than those of non-fathers. 较之无后代的绒猴,做了父亲的绒猴的额前页神经细胞具有更多的微小的突起,即树突棘。
- They find decreased dendritic branching in the hippocampus in first-time dams at the time of weaning and more dendritic spines in second-time moms. 他们发现第一次产仔的大鼠在断奶的时候,海马体中的树突有所减少,而在第二次产仔的大鼠中则有所增加。
- In addition, the authors replicated the effects of stress on dendritic spines by administering low levels of synthetic CRH, and watching how the spines retracted over minutes. 除此之外,研究者们还通过注射少量的合成促肾上腺皮质激素模拟压力对树突刺的影响,观察树突刺在几分钟内收缩的状况。
