Rapid learning of neural circuitry from holographic ensemble stimulation enabled by model-based compressed sensing

Posted by klaurent Columbia

Kavli Affiliate: Liam Paninski | Authors: Marcus A. Triplett, Marta Gajowa, Benjamin Antin, Masato Sadahiro, Hillel Adesnik and Liam Paninski | Summary: Abstract Discovering how neural computations are implemented in the cortex at the level of monosynaptic connectivity requires probing for the existence of synapses from possibly thousands of presynaptic candidate neurons. Two-photon optogenetics has […]
