Title : Notch Signaling

Speaker: Kelsey Martin

Summary: Notch signaling plays critical roles during the development of the nervous system. Several studies have suggested that Notch signaling in neurons is also involved in learning and memory and synaptic plasticity in the mature brain. However, these studies have been suggestive rather than conclusive. Moreover, studies from Ben Barres indicate that Notch receptor and ligands are expressed at very low levels in mature neurons, and at very high levels in glia. I will present a paper from Nick Gaiano's lab that argues that Notch signals from synapse to nucleus in mature hippocampal neurons and that this signaling is required for long-term potentiation and memory acquisition. Gaiano's data further indicates that the immediate early gene arc regulates Notch signaling in neurons.

The reference for the primary paper is:

Activity-induced notch signaling in neurons requires arc/arg3.1 and is essential for synaptic plasticity in hippocampal networks.

Title : The dendritic branch is the preferred integrative unit for protein synthesis-dependent LTP.

Speaker: Walter Babiec

Summary: The late-phase of long-term potentiation (L-LTP), the cellular correlate of long-term memory, induced at some synapses facilitates L-LTP expression at other synapses receiving stimulation too weak to induce L-LTP by itself. Using glutamate uncaging and two-photon imaging, we demonstrate that the efficacy of this facilitation decreases with increasing time between stimulations, increasing distance between stimulated spines and with the spines being on different dendritic branches. Paradoxically, stimulated spines compete for L-LTP expression if stimulated too closely together in time. Furthermore, the facilitation is temporally bidirectional but asymmetric. Additionally, L-LTP formation is itself biased toward occurring on spines within a branch. These data support the Clustered Plasticity Hypothesis, which states that such spatial and temporal limits lead to stable engram formation, preferentially at synapses clustered within dendritic branches rather than dispersed throughout the dendritic arbor. Thus, dendritic branches rather than individual synapses are the primary functional units for long-term memory storage
