Auto- and cross-covariances across time in our sample of 165 pairs of MT neurons
| Time Interval T1 | Time Interval T2 | ||
|---|---|---|---|
| Neuron a | σ2 | ––γ2 = 0.15–– | σ2 |

| | | ρ2: | | | |
| | ϕ2 = 0.063 | cov (a1, b2) = 0.021 | | ϕ2 = 0.062 | |

| Neuron b | σ2 | ––γ2 = 0.13–– | σ2 |
As described in the text, σ2 is the response variance during each time epoch; ϕ2 is the covariance between the responses of two neurons during the same time epoch; ρ2 is the covariance between the responses of two neurons during different tome epochs (reflecting cross-temporal correlation); and γ2 is the covariance between the responses of the same neuron during different time epochs (reflecting autotemporal correlation). Numbers were obtained by analysis of our sample of MT neuron pairs during T1 = T2 = 200-ms time intervals.
