Fig. 5From: Multiscale analysis of slow-fast neuronal learning models with noiseThis is the spectral profile | v ∗ v ′ ˆ |(ξ) for β=1 and l∈]0,2], where v ∗ v ′ ˆ denotes the Fourier transform of v∗ v ′ . When 4l<β, the filter reaches its maximum for the null frequency, but if l increases beyond β 4 , the filter becomes a band-pass filter with long tails in 1 ξ 2 .Back to article page
