(A) Location of somatosensory and motor areas based on the anatomical database by Allen Brain Atlas. The background image indicate a raw fluorescence signal obtained from voltage imaging. …
(A) Singular Value Decomposition efficiently compresses calcium-imaging data. Example GCaMP traces in V1, using 5 numbers of SVD components, from 50 to 2000 components. The resulting five traces …
(A) Seed-area maps of correlation from an example animal expressing a voltage indicator. Correlation was computed against the average signal within the red square to signals of the all the other …
This analysis was performed on six mice where we had measured both active and passive condition, and where all six visual areas were identified functionally. Two of these mice expressed VSFP (orange)…
(A) Three example sequences of voltage signal during the period after presentation of 50% contrast to the left monocular visual field in an example mouse expressing VSFP. In each examples, the …
(A) Mean calcium signal across trials from seven animals in the right stimulated V1 (red) and in the left unstimulated V1 (black). Time period of 50–150 ms after stimulus onset (shaded area) was …
(A) Single trial traces aligned by the onset of visual stimulation of 100% contrast to the left visual field in the left unstimulated PM and right stimulated PM. The time period (50–150 ms) used for …
(A) Template obtained as average visual response to left and right 100% contrast stimuli obtained from one animal. (B) Example single-trial responses to after presentation of 100% contrast the the …
(A) Instantaneous amplitude at unstimulated PM (vertical axis) and pre-stimulus fluctuation amplitude between 2–7 Hz at stimulated PM (horizontal axis) of single trials in area PM. Each dot …
Same as Figure 5—figure supplement 2, except that trials are divided by prestimulus pupil diameter instead of cortical state.
(A) Cross-correlation between activity in left and right PM, in individual mice (colored traces) and across all seven mice (black trace). (B) Activities 50–150 ms after visual stimulation of 100% …
(A) Probability of turning the wheel to the correct direction as a function of stimulus contrast in one animal. The probability is computed separately in trial groups of low (blue) and high (cyan) …
(A) Probability of turning the wheel to the correct direction as a function of stimulus contrast in one animal. The probability is computed separately in trial groups of negative (dark green) and …
(A) Schematic representation of the additive model (Equation 1). (B) Single-trial PM traces predicted by the additive model. (B1) bilateral activity, estimated from left PM. (B2) visually evoked …
(A) Variance of activity in each visual area explained by the additive model, as a function of distance from location of the corresponding area in the other hemisphere. Gray curves indicate results …
A few tens of components are sufficient to capture close to 100% of the variance, both in the calcium-sensitive channel (blue) and in the calcium-independent channel (red). In the paper, we use 500 …
The resulting five traces look identical. The number of components used in the paper is 500.
Left: Results obtained after taking the derivative and lowpass filtering (as used in our paper). Right: Results obtained without any filtering. By definition, filtering affects the power spectral …
