Credit Assignment OpenScope Project Deployment Scripts

This repository contains the stimulus scripts used to generate the stimuli for the Credit Assignment project, an Allen Institute for Brain Science OpenScope project.

The Credit Assignment experiment was conceptualized by Joel Zylberberg (York University), Blake Richards (McGill University), Timothy Lillicrap (DeepMind) and Yoshua Bengio (Mila), and the stimuli were coded by Colleen Gillon.

These scripts have been updated since the dataset described in Gillon et al., 2023, Sci Data was collected. For the exact scripts used in the experiments reported in that paper, see the commit tagged as production_v1.

NOTE: Whereas this repository contains the exact scripts deployed for data collection in the OpenScope pipeline, the cred_assign_stimuli repository contains the same base code, but modified to allow users to conveniently visualize, reproduce and save the stimuli described in our dataset descriptor paper, Gillon et al., 2023, Sci Data, and analysis paper, Gillon, Pina et al., 2024, J Neurosci. It also contains a more detailed description of the stimulus design.

Stimulus design

Sparse Gabor sequences (adapted from Homann et al., 2022, PNAS)

Installation

Dependencies:

Windows OS (see Camstim package)
python 2.7
psychopy 1.82.01
camstim 0.2.4

Camstim 0.2.4:

Built and licensed by the Allen Institute.
Written in Python 2 and designed for Windows OS (requires pywin32).
Pickled stimulus presentation logs are typically saved under user/camstim/output.

Installation with Anaconda or Miniconda:

Navigate to repository and install conda environment.
conda env create -f cred_assign_stimuli.yml
Activate the environment.
conda activate cred_assign_stimuli
Install the Allen Institute's camstim package in the environment.
pip install camstim/.
Download and install AVbin for your OS.

Scripts

`pilot_scripts` : scripts used for the pilot deployment

habituation_rig : scripts used on the habituation rig. For each habituation day, a different script is used, shared across all subjects,
e.g., run python pilot_scripts/habituation_rig/day7.py.
ophys_rig : scripts used on the optical physiology rig. For each experiment day, a different script is used, shared across all subjects,
e.g., run python pilot_scripts/ophys_rig/ophys_record.py.

`production_scripts` : scripts used for the production deployment

Not yet created.

Log files

Pickled stimulus presentation logs are typically saved under user/camstim/output.
Sweep parameters are under a few keys of ['stimuli'][n], where n is the stimulus number.
Stimulus parameters are in dictionaries stored under: ['stimuli'][n]['stim_params'].

Reproduction

There are several randomly generated components to the stimuli in each session:

Gabor positions and sizes,

Gabor sequence block order,

Gabor sequence orientations,

Unexpected event ("surprise") onsets and duration.

The stimuli can be reproduced using the recorded seed, as the random state is used to generate all 4 random components.
The same display size must be reused during reproduction.

Code

Code and documentation (excluding camstim) built by Colleen Gillon (colleen dot gillon at mail dot utoronto dot ca).
