This is a repository containing a script for matching neuronal recordings together as coming from the same putative unit or not

A parser for EyeLink data files, built on python-datamatrix. The code base is by Mathot, this fork makes it a proper, tested and runnable package.

Pupil size tracking pipeline based on PupilSense

A set of functions to control luminance of colored images.

Chang & Tang et al., Nature (2025), An open-source implementation of a real-time pupil tracking and closed-loop control system for neuroscience experiments

Computational modeling pipeline integrating pupillometry, behavioral data, and drift diffusion models (DDM) to understand the relationship between brain arousal and decision-making processes.

Preprocess and plot pupil diameter data

R functions for processing pupillary light reflex (PLR) recordings — artifact removal, feature extraction, and batch analysis

A method for segmentation and measurement of mouse pupil from video sequences.

Pupil reactivity to brief sounds.

Online Material for Vidal et al. (2024). Cholinergic-related pupil activity reflects level of emotionality during motor performance. EJN, 59(9):2193–2207.

The pupillometryAnalyzer script can be used to analyse pupillometry raw data saved in a wks-file. It analyzes the time-series of one or both eyes and creates informative csv- and png-outputs that can be used for further statistical analysis.

Real-time LF/HF pupillometric cognitive load via Butterworth IIR filters (Duchowski 2026). Includes AdSERP validation on 2,719 eye-tracking trials.
