Spalloc

The SpiNNaker Allocation Service (Spalloc) allows the board of the SpiNNaker 1Million machine to be split up into user allocations of groups of a number of connected boards. These boards are isolated from the rest of the machine by the service, ensuring that one user’s simulation does not interfere with another. The service allows users to log in using EBRAINS usernames and passwords to see and control their existing allocations. The service also provides a proxy connection to the boards using websockets, which allows the allocation to be used from anywhere in the world. This is used by the SpiNNaker software to enable access to the machine from the EBRAINS Jupyter lab.

Data analysis and visualisation

3DSpineMFE

A MATLAB® toolbox that given a three-dimensional spine reconstruction computes a set of characteristic morphological measures that unequivocally determine the spine shape.

Modelling and simulation

3DSpineS

Dendritic spines of pyramidal neurons are the targets of most excitatory synapses in the cerebral cortex and their morphology appears to be critical from the functional point of view. Thus, characterizing this morphology is necessary to link structural and functional spine data and thus interpret and make them more meaningful. We have used a large database of more than 7,000 individually 3D reconstructed dendritic spines from human cortical pyramidal neurons that is first transformed into a set of 54 quantitative features characterizing spine geometry mathematically. The resulting data set is grouped into spine clusters based on a probabilistic model with Gaussian finite mixtures. We uncover six groups of spines whose discriminative characteristics are identified with machine learning methods as a set of rules. The clustering model allows us to simulate accurate spines from human pyramidal neurons to suggest new hypotheses of the functional organization of these cells.
