***New preprint from the lab*** showing “Generative replay across hippocampal-neocortical circuits”. In sleep we show spiking sequences in V1 (sensory neocortex!) that represent information that has not been directly experienced www.biorxiv.org/content/10.6... @bndu.ox.ac.uk @ndcnoxford.bsky.social

Generative replay across hippocampal-neocortical circuits

To make flexible decisions, the brain needs to make inferences between events that were not directly experienced together. In sharp-wave ripple (SWR) events, during periods of rest and sleep, spiking ...

New perspective paper from our lab: “The hippocampus as a generative model” out now !! royalsocietypublishing.org/rstb/article... The traditional view of the hippocampus is that it creates a cognitive map. Here we extend this view to conceptualise the hippocampus as a “generative model”.

The hippocampus as a generative model

Abstract. A generative model can be defined as a model of the latent causes of sensory input that can be used to generate new data samples. By examining em

Interested in human replay and solid methods? Jointly with @skjerns.de we're releasing a benchmark dataset with known ground-truth neural sequences in MEG & fMRI, for developing & validating replay methods. First test: existing methods show similar effect sizes, but room to improve shorturl.at/6TgIr

FASTIMAGES: Validating replay detection methods in human neuroimaging using a combined MEG and fMRI dataset

Studies in rodents and humans using invasive electrophysiology have established that neural replay is a ubiquitous phenomenon in the brain that is associated with a wide range of cognitive functions, ...

Oxford, the longest running continuous weather station in UK history, with temperature observations stretching back to 1815, has preliminarily broken its maximum temperature record for May yesterday by OVER 3ºC with a temperature of 33.7ºC. Unprecedented in its 211-year history.

Spaghetti chart showing Oxford Radcliffe Observatory daily maximum temperatures for every day of the year from 1815 to 2026. 211 years of historical data are shown as very faint grey lines tracing a seasonal cycle from around 5°C in winter to a summer peak of roughly 25–30°C in July and August. A blue smoothed 30-day mean line highlights the average annual temperature cycle. The 2026 line is shown in bold red, running from January through to late May before spiking sharply upward to reach 33.7°C on 26 May, well above the entire historical grey envelope for that time of year. A single dashed red reference line marks the previous May record of 30.6°C set on 29 May 1944. The 2026 reading exceeds this by 3.1°C and, in statistical terms, is the 6th most anomalous maximum temperature in Oxford's 211-year record, ranking as the most anomalous May maximum ever observed and coming within 0.6°C of the all-time June record of 34.3°C set in 1976.

Interested in cognitive maps? Wondering how you should best train your participants? Luckily for you, we have investigated just that! Very excited to share a preprint from my PhD in which we show how initial training curriculum affects the cognitive maps we form osf.io/preprints/ps... [1/6]

🧠✨How do we rebuild our memories? In our new study, we show that hippocampal ripples kickstart a coordinated expansion of cortical activity that helps reconstruct past experiences. We recorded iEEG from patients during memory retrieval... and found something really cool 👇(thread)
