[Comp-neuro] What is the precision of synaptic plasticity?

http://biorxiv.org/content/early/2015/03/11/016329 Hippocampal Spine Head Sizes are Highly Precise Thomas M Bartol, Cailey Bromer, Justin P Kinney, Michael A Chirillo, Jennifer N Bourne, Kristen M Harris, Terrence J Sejnowski The size of an EPSP is highly correlated with the the spine head volume for excitatory synapses on pyramidal cells. Spine heads on a dendrite originating from the same axon had the same volume, regardless of whether they were large or small. This has implications for the precision of the mechanisms underlying synaptic plasticity. Terry -----
