Overview

Yuan Lab is led by Prof. Zhen Yuan, Professor in the Faculty of Medicine and Head of the Centre for Cognitive and Brain Sciences at the University of Macau. The group sits where biomedical optics meets cognitive neuroscience: it builds and applies optical and electromagnetic instruments to ask how the human brain supports cognition, and how that organisation changes in neurological and psychiatric illness.

The laboratory's principal instrument is functional near-infrared spectroscopy (fNIRS). It is silent, portable, tolerant of head movement, and cheap enough to run for hours — which puts it in places an MRI scanner cannot go: beside a hospital bed, on a young child, or across two people interacting at the same time. fNIRS is routinely combined with EEG, structural and functional MRI, and computational modelling of behaviour, so that a haemodynamic signal can be read against electrical activity, anatomy and choice.

The archive is what that work leaves behind: one directory per recording campaign or derived dataset, tagged by the modality it was acquired with and the research area it serves.

It currently holds 128 dataset directories across 3 storage volumes, tagged with 11 modalities and 15 research areas.

Research directions
Neurophotonics & fNIRS
Instrumentation, forward modelling and signal processing for diffuse optical measurement of cortical haemodynamics — diffuse optical tomography, wearable and movement-tolerant systems.
fNIRS · DOT
Multimodal fusion & hyperscanning
Pairing fNIRS with EEG and MRI so that haemodynamic and electrophysiological signals constrain each other; measuring inter-brain coupling while two people cooperate, compete or learn together.
EEG · fNIRS · MRI
Brain disorders & cognition
Addiction and behavioural dependence, depression and insomnia, autism and Down syndrome, the Alzheimer's continuum — and ordinary cognition: decision-making, executive function, language learning.
Clinical & cognitive
Biomedical optics & molecular imaging
Photoacoustic tomography and microscopy, optical coherence tomography, nanoparticle contrast agents for imaging and light-activated therapy — the instrument physics the neuroimaging work draws on.
PAT · OCT · nanomedicine

Search the collection

Filter by modality and research focus. The ring distribution is fixed — categories excluded by the current filter are dimmed rather than removed. The panel on the right shows what remains in this combination. Only aggregate counts appear here: no paths, no names.

Match Applies within one dimension; across the two dimensions it is always AND
Outer · modality Inner · research focus

Where these two dimensions come from

Modality and research focus are not hand-entered — they are parsed from directory names. The group already uses a project_modality_date_version convention (e.g. sca3_cj_fmri_20261109), and the parser only accepts words that are actually present in the name; anything it cannot read is filed as Unlabelled rather than guessed. When the name gives no clue, the second-level subdirectory is used as secondary evidence (e.g. AD数据汇总\AD原始脑电 → EEG), and the evidence word is recorded. Currently 29 datasets have no modality clue and 51 no focus clue; both appear as grey segments on the ring and can be clicked to list them on their own. Filling these in is the next task.
