Tracing a Path for Memory in the Hippocampus

Neuron. 2020 Jul 22;107(2):199-201. doi: 10.1016/j.neuron.2020.06.034.


The hippocampal activity supporting trace fear conditioning has long been mysterious, but a leading hypothesis posits "time-cell"-like sequential patterns. In this issue of Neuron, Ahmed et al. (2020) present new data suggesting that, at least during the first session of learning, a subset of neurons coalesce to selectively encode the task but without expressing reliable sequences.
