We have a new preprint, examining what happens at the single neuron level in humans while people emerge from anaesthesia. Link: www.biorxiv.org/content/10.6.... tldr: neurons in medial temporal lobe (and thalamus, albeit limited data) often show increases in activity way before overt responses 🧠🟦 🧠💻

We have a new preprint examining single neuron responses in humans undergoing TMS (www.biorxiv.org/content/10.6...). The excellent Charlie Dickey led the way, and I had the privilege to co-supervise this work with @coreykeller.bsky.social and @aaronboes.bsky.social 🧵 (1/7) 🧠🟦 🧠💻
Image showing the paradigm for recording single neurons in a variety of brain regions in humans, while single-pulse TMS was applied to dlPFC. One subpanel shows that single neurons were able to be resolved very early (8ms) after the single-pulse stimulation. Another subpanel shows two example neuron waveforms, along with their inter-spike interval distributions. The final subpanels show spike density functions overlaid on raster plots for the same neuron, separately for active and sham stimulation, in order to demonstrate that active (but not sham) stimulation increased activity in this example neuron.

Our new preprint is out! We show that deviance detection in auditory cortex conveys the theorised comparison of internal prediction to sensory input. Our data confirm this key assumtion that links theoretical models of sensory processing to experimental data. www.biorxiv.org/content/10.6...

Context modulates neural processing of sensory stimuli. Neural responses are suppressed to stimuli that are typical in their context and augmented to stimuli that deviate from their context. The latte...

Are you curious about electrogastrography, but keep getting chicken-related results when googling "EGG"? We have the preprint for you! In this tutorial, we describe how to acquire and analyse gastric data from human participants. Plus FREE software! Read it here: arxiv.org/abs/2509.17260
Image illustrating sensor placement. The reference sensor is placed on the xiphoid process (just under the sternum), the ground is placed on the left costal margin (just under the bottom rib), and sensors one through four are place over where the stomach would be. Sensor 3 is midway through the umbilicus (navel) and the reference sensor. Sensor 4 is roughly three centimetres from sensor 3 to participant-right. Sensors 2 is also roughly three centimetres away from sensor 3, but along a 45 degree angle upwards and to participant-left. Sensor 1 lies 3 centimetres further from sensor 2, along the same 45 degree line.Two-panel image showing a processed electrogastrogram. The left panel shows five minutes of raw data from four different leads (measured from the four sensors in the previous image and their common reference). The right panel shows the same signal in frequency space, illustrating the typical normogastric peak at 3 cycles per minute.

fMRI signals “up,” but neural metabolism might be going “down.” In our @natneuro.nature.com paper, we demonstrate that about 40% of voxels with robust BOLD responses exhibit opposite oxygen metabolism, revealing two distinct hemodynamic modes. rdcu.be/eUPO8 funds @erc.europa.eu #neuroskyence 🧵:

New results! Despite their varied molecular actions, anesthetics alter brain wave alignment in the same way. Convergent effects of different anesthetics are due to changes in phase alignment of cortical oscillations www.biorxiv.org/content/10.1... #neuroscience

Our new paper on tinnitus and the hippocampus is out now in Human Brain Mapping: doi.org/10.1002/hbm.... The TL;DR is that we are highlighting a role for the hippocampus that focuses on sustaining the memory of a phantom percept, based on current literature. 1/4 🧠📈 #PsychSciSky
