Dataset Structure

The decoding scans are provided as .h5 files. There are two types of decoding scans:

Objects: For the object discrimation task
Ellipse: For the detection task

The following attributes are present in each individual dataset:

pupil_trials: mean pupil size for each trial
- shape:n_trials,
class_trials: image class for each trial. See below for details.
- shape:n_trials,
activity_trials: mean activity per neuron for each trial
- shape:n_neurons x n_trials

`class_trials` description

Object discrimination task

Paradigm 1

o1BLfgv2: object 1, green channel, foreground (Fig. 5)
o2BLfgv2: object 2, green channel, foreground (Fig. 5)
o1UVfgv2: object 1, UV channel, foreground (Fig. 5)
o2UVfgv2: object 2, UV channel, foreground (Fig. 5)

Paradigm 2

o1BLfbv2: object 1, green channel, foreground & background & positive contrast (Extended Data Fig. 10)
o2BLfbv2: object 2, green channel, foreground & background & positive contrast (Extended Data Fig. 10)
o1UVfbv2: object 1, UV channel, foreground & background & positive contrast (Extended Data Fig. 10)
o2UVfbv2: object 2, UV channel, foreground & background & positive contrast (Extended Data Fig. 10)

Paradigm 3

o1BLfdv2: object 1, green channel, foreground & background & negative contrast (Extended Data Fig. 10)
o2BLfdv2: object 2, green channel, foreground & background & negative contrast (Extended Data Fig. 10)
o1UVfdv2: object 1, UV channel, foreground & background & negative contrast (Extended Data Fig. 10)
o2UVfdv2: object 2, UV channel, foreground & background & negative contrast (Extended Data Fig. 10)

Paradigm 4

o1BLnbv2: object 1, green channel, no background/foreground (Extended Data Fig. 10)
o2BLnbv2: object 2, green channel, no background/foreground (Extended Data Fig. 10)
o1UVnbv2: object 1, UV channel, no background/foreground (Extended Data Fig. 10)
o2UVnbv2: object 2, UV channel, no background/foreground (Extended Data Fig. 10)

Detection task

green: dark ellipse is present in the green color channel
uv: dark ellipse is present in the UV color channel
noise: no ellipse is present
