Abstract
Long-term potentiation (LTP), is a type of synaptic plasticity now considered essential for learning and memory. Here I tell the story of how I accidentally discovered in 1966 in the laboratory of Per Andersen in Oslo, Norway, because I was not looking for it. It just emerged. I recount how I came to work with Per and why my result was not immediately followed up. Then, in 1968 Tim Bliss joined the lab and, on his urging, from 1968 to 1969 we did the experiments that resulted in Bliss and Lømo, 1973. I explain why I think the experiments later failed in Oslo, and for a few years also in Tim's lab in London, before it became a readily observable phenomenon. I also describe how Tony Gardner-Medwin and I in 1971 failed to reproduce the results that Tim and I had obtained 2 years earlier in the same lab and the same type of anesthetized rabbit preparation. I tell how this failure caused me to leave the LTP field and, instead, continue exploring mechanisms of nerve–muscle interactions, which I had studied with much success during my postdoc period in London from 1969 to 1971. I reflect on Donald Hebb's influence on LTP studies and on my experience when after many years of neglect, I became interested in LTP and the hippocampus anew and started to write about it, though without doing lab experiments. Finally, I report briefly on the experiments I am doing now in retirement, studying how the nervous system regulates body temperature through varying amounts of muscle tone.
期刊介绍:
Hippocampus provides a forum for the exchange of current information between investigators interested in the neurobiology of the hippocampal formation and related structures. While the relationships of submitted papers to the hippocampal formation will be evaluated liberally, the substance of appropriate papers should deal with the hippocampal formation per se or with the interaction between the hippocampal formation and other brain regions. The scope of Hippocampus is wide: single and multidisciplinary experimental studies from all fields of basic science, theoretical papers, papers dealing with hippocampal preparations as models for understanding the central nervous system, and clinical studies will be considered for publication. The Editor especially encourages the submission of papers that contribute to a functional understanding of the hippocampal formation.
