Intrinsic firing patterns of diverse neocortical neurons
... It is axiomatic in neuroscience that the informational output of most neurons is completely defined by their temporal patterns of action potentials. This notion is implicit in all contemporary models of the functions of neocortex, making it essential to understand how each neuron transforms its inpu ...

Practical 6: Ben-Yishai network of visual cortex
... d) Take λ0 = 5, λ1 = 0, ϵ = 0.1. This means that there is uniform recurrent inhibition. Vary the contrast c (range 0.1 to 10) and observe the steady state. You will see three regimes: no output, a rectified cosine, and a cosine plus offset. e) Next, take a small value for ϵ, take λ0 = 2, and vary λ1 ...
