Useful circuit reconstruction requires the identification of circuit components as well as the abstraction of circuit connectivity diagrams. In reconstructing (or “reverse‐engineering”) human‐engineered circuits, the challenges of component identification are usually relatively inconsequential, because component diversity is small, and much is generally known in advance, including appropriate component classification schemes (e.g., mosfet, capacitor, etc.). In the case of neural circuits, however, the identification of component properties involves challenges that may be far more formidable. Both gene expression and physiological data suggest today that neural circuit components, such as synapses and dendrites, could be almost limitless in their molecular, structural and functional diversity.
We are using array tomography (Micheva & Smith, Neuron, 55:25‐36, 2007) to: (1) empirically define the extent of synapse molecular and structural diversity, (2) discover categories that encapsulate the major components of synapse diversity (i.e., a “Synaptome”), and, (3) identify a compact set of markers optimal to classify synapses during high‐throughput connectomic imaging. We have chosen rectangular slabs of mouse somatosensory cortex that extend through the entire cortical depth as a representative and amenable “microcosm” of CNS circuitry. We are using a panel of antibody markers chosen to identify synapse classes that might be based, for instance, on differing neurotransmitter receptor and transporter types. We anticipate that a synaptome will prove useful as a framework for the better understanding of the large‐scale circuit connectivity diagrams that will be connected in the years ahead by means such as KESM, and for better understanding the differential susceptibilities of subsets of neurons and synapses to neurodevelopmental and neurodegenerative disorders.
