Oligomers Help Us Keep Our Memories
A protein whose molecules have the special ability to stack on top of one another, somewhat like egg cartons, and thus form short, highly stable chains (oligomers), may well play a key role in the mechanisms by which we maintain lasting memories.
Indeed, there is always something magical about remembering something that you haven’t thought about in years. But physically speaking, in what form is the corresponding memory trace maintained in your brain over all that time? Neurobiologists know that the whole process occurs in the synapses (the plastic connections between neurons) and have described molecular mechanisms such as long-term potentiation that partly explain this plasticity.
