+summary: Neuronal modeling software spanning molecules, electrophysiology and networks
+description: |
+    MOOSE is the Multiscale Object-Oriented Simulation Environment. It is designed
+    to simulate neural systems ranging from biochemical signaling to complex models
+    of single neurons, circuits, and large networks. A typical use case is to model
+    neural activity-driven synaptic plasticity, in which network activity to
+    synapses triggers biochemical reaction-diffusion events, which in turn modulate
+    ion channels to give rise to synaptic plasticity.
