TL;DR: It is proposed that compartmentalized changes in branch excitability could store multiple complex features of synaptic input, such as their spatio-temporal correlation, and that this ‘branch strength potentiation’ represents a previously unknown form of information storage that is distinct from that produced by changes in synaptic efficacy both at the mechanistic level and in the type of information stored.

TL;DR: Using multisite two-photon glutamate uncaging to deliver different spatiotemporal input patterns to single branches while simultaneously recording the uncaging-evoked excitatory postsynaptic potentials and local Ca2+ signals suggests that individual branches can function as single integrative compartments.

TL;DR: Findings indicate that perisomatic and dendritic inhibition have distinct roles in controlling the rate, burst and timing of hippocampal pyramidal cells.

TL;DR: Subcortical activation of dendritic inhibition is proposed as a mechanism for exclusion of aversive stimuli from hippocampal contextual representations during fear learning.

TL;DR: It is suggested that distinct memory traces are located in the DG and in CA3 but that the strength of the memory is related to reactivation in CA4 and not in DG or CA3.
