... Future work will involve testing the key predictions of the model by inactivating the Ipc, while recording in the OT (in-vivo), as well as microstimulating Ipc (in-vitro) to test if ACh input to OT can induce synchrony. The transient increase in synchrony upon stimulus offset will be incorporated in ...

... Thus, we would expect to find very few ‘redundant’ neurons with co-varying outputs in that network. Accordingly, an optimal temporal coding circuit might tend to eliminate redundancy in the pattern of inputs to different neurons. On the other hand, if neural information is carried by a noisy rate-ba ...

If the presynaptic spike occurs before the postsynaptic spike, it probably helped cause the postsynaptic spike, and consequently we should encourage this by increasing the synaptic weight. And if the ...
