dendrite: Dendritic Spines Data

Description

Dendrites are branching filaments which extend from the main body of a neuron (nerve cell) to propagate electrochemical signals. Spines are small protrusions on the dendrites.

This dataset gives the locations of 566 spines observed on one branch of the dendritic tree of a rat neuron. The spines are classified according to their shape into three types: mushroom, stubby or thin.

The data have been analysed in Jammalamadaka et al (2013) and Baddeley et al (2014). Please cite these papers and acknowledge the Kosik Lab, UC Santa Barbara, in any use of the data.
