The second uses the spatial connectivity of a circuit to achieve specificity: one genetic element is introduced at the origin of a circuit and the other at its termination. When the two genetic elements combine within a neuron, they can alter its function.

Genetic-identity-based and connectivity-based targeting approaches can be combined to manipulate neurons with a specific genetic identity within a defined circuit.
The review considers advantages and disadvantages of the two general circuit-targeting approaches with regard to specificity and efficacy of manipulations.
The review describes two general approaches for achieving neural circuit specificity: targeting by genetic identity and targeting by spatial connectivity.
