Calcium Dynamics of Spines Depend on Their Dendritic Location
Open accessAbstract
Dendritic spines are morphologically and functionally heterogeneous. To understand this diversity, we use two-photon imaging of layer 5 neocortical pyramidal cells and measure action potential-evoked [Ca(2+)]i transients in spines. Spine calcium kinetics are controlled by (i) the diameter of the parent dendrite, (ii) the length of the spine neck, and (iii) the strength of spine calcium pumps. These factors produce different calcium dynamics in spines from basal, proximal apical, and distal apical dendrites, differences that are more pronounced without exogenous buffers. In proximal and distal apical dendrites, different calcium dynamics correlate with different susceptibility to synaptic depression, and modifying calcium kinetics in spines changes the expression of long-term depression. Thus, the spine location apparently determines its calcium dynamics and synaptic plasticity. Our results highlight the precision in design of neocortical neurons.

In the citing paper
“Nevertheless, morphology does play a role, as long and thin necks prevent the diffusion of calcium, whereas shorter and thicker necks allow for better diffusional coupling with the dendrite (Majewska et al., 2000; Holthoff et al., 2002; Sabatini et al., 2002; Korkotian et al., 2004; Noguchi et al., 2005).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
