We used data from the LAION-fMRI dataset (CITATION, YEAR), an open fMRI dataset comprising [N] participants who viewed [N] unique natural images during event-related fMRI scanning at [X]T. Single-trial response estimates were obtained using GLMsingle (Prince et al., 2022).

We used functional and anatomical MRI data from the LAION-fMRI dataset (CITATION, YEAR; freely available at [URL]). The dataset includes [N] healthy adult participants ([N] female, mean age [X] +/- [X] years), each of whom completed [N] scanning sessions. In each session, participants viewed [N] unique natural images presented for [X] ms each in an event-related design while performing a [task description]. Functional images were acquired on a [manufacturer] [field strength] [model] scanner using a [sequence] (TR = [X] s, TE = [X] ms, [X] mm isotropic voxels, multiband factor = [X]). High-resolution T1-weighted anatomical images ([X] mm isotropic) were also acquired for each participant.

Functional data were preprocessed using [pipeline] ([version]; CITATION), including [list key steps]. Single-trial beta estimates were computed using GLMsingle (Prince et al., 2022), which optimizes the hemodynamic response function per voxel, applies data-driven denoising (GLMdenoise), and regularizes estimates via ridge regression.
