Research

Four questions we work on

A short introduction to the program. For a specific paper, see all publications, by topic.

Can EEG interpretation be made more reliable and scalable?

MORGOTH, an EEG foundation model

Reading EEG takes scarce expert time. MORGOTH is a single model for comprehensive automated interpretation, developed and validated at multiple centres.

How much do experts agree?

We measured interrater reliability among expert electroencephalographers identifying seizures and rhythmic and periodic patterns, and the noise in expert diagnosis of epilepsy.

Detecting epileptiform spikes

SpikeNet is a deep learning model for automated detection of interictal epileptiform discharges in EEG.

What does sleep reveal about brain health?

Brain age and brain health from sleep EEG

A brain age estimated from one night's EEG, and a sleep-derived brain health score studied against long-term cognitive decline.

Breathing instability during sleep

Dynamic instability of breathing during sleep, quantified from routine recordings, predicts cognition, disease and mortality.

CAISR, the Complete AI Sleep Report

Automated scoring of clinical sleep studies, so that large sleep datasets can be analysed consistently.

How should brain monitoring inform care in critical illness?

Coma after cardiac arrest

EEG patterns and their prognostic significance in a multicentre cohort of 1,000 patients, and an international EEG database for outcome prediction research.

Seizures and the ictal-interictal continuum

SPaRCNet classifies seizures and rhythmic and periodic patterns in ICU EEG; GROND describes those patterns quantitatively.

How can shared data and clinical records speed up neurological research?

Brain Data Science Platform

Clinical EEG, sleep and ECG datasets released for reuse, including the Human Sleep Project and the Harvard-Emory ECG Database.

Phenotypes from the medical record

Methods that extract diagnoses and outcomes from clinical notes, such as cognitive impairment and functional outcome after cardiac arrest.
