1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

This essay describes the development of the in vitro hippocampal slice technique and my small contributions to it and to influencing Roger Nicoll's early interests in the hippocampus and LTP. My Ph.D. work at Harvard with Timothy Teyler was on field potential studies of synaptic plasticity, including LTP, in the rat in vitro hippocampal slice. As a postdoc, I introduced the slice preparation to Roger Nicoll's lab at UCSF but failed to interest him in LTP. Here I explain how Nicoll's scientific philosophy both motivated me to develop our first submersion slice chamber and kept him from investigating LTP for nearly a decade. Finally, I recount the history of the name "LTP."
