Chemical synapses between neurons of the fly visual medulla
Search for synaptic contacts between specified cells:

would match any cells starting with L1.
- Separate entries for multiple cells with commas.
L1 209, L2*
would match L1 209 as well as all cells
starting with L2.
- Within a central, reference medulla column, two proofreaders attempted to
assign each synaptic contact to its pre- and postsynaptic neurons. In approx.
50% of the cases, they were able to complete the assignment, achieving >90%
certainty for the assigned synapses. The 50% assignment rate implies that any
pair of neurons in the central column
(detailed here) connected with >5
contacts is present with >95% probability and, similarly, any pair of neurons
in the central column that is unconnected has ≤ 5 synaptic contacts (again
with >95% probability).
- Outside of the central column, synaptic contacts between L1 and Tm3 neurons,
Tm3 and T4 neurons, and Mi1 and T4 neurons were traced by an expert
proofreader. Synaptic contacts between other neurons outside the reference
column were not uniformly traced.
- We reserve the right to update the number of synaptic contacts in the future.

A bug was noted in this website on Nov 8, 2013 that resulted in the false absence from search
results of any neurons that only received synaptic contacts (i.e., purely postsynaptic neurons).
