Fig 5. Low-pass and high-pass temporal frequency tuning.

A) An example of a cell showing low-pass temporal frequency tuning. Open circles indicate mean firing rates across four repeated presentations of drifting gratings (high₅₀ 1.1 Hz). Black curves show the best fits of a two-half-Gaussian function. Grey areas represent SEM of spontaneous activity, with thinner lines indicating mean. Inset: high₅₀ of all low-pass cells. B) An example of a cell showing high-pass temporal frequency tuning (low₅₀ 1.4 Hz). Inset: low₅₀ of all high-pass cells.
