WebThe ventral hippocampus (VH) was recently shown to express lower magnitude LTP compared to the dorsal hippocampus (DH). Exposure to acute stress reversed this difference, and VH slices from stressed rats expressed larger LTP than that produced in the DH, which was reduced by stress. In an attempt to uncover the mechanisms responsible … WebDownload scientific diagram Primed burst stimulation (PBs) was able to reliably induce persistent LTP at TA-CA1 synapses as compared to theta-burst stimulation (TBS).
