This study estimates histological safety boundaries for cathodal DC stimulation in ovine brains, finding no damage at low charge densities and increasing lesion risk with higher doses.

Network and hierarchical organization of intrinsic timescales in the human brain

This paper measures neural timescales in human iEEG data and links them to cortical hierarchy and network topology, showing that timescales increase with hierarchical position and are modulated by sleep stages.

Early reactivation of medial temporal lobe neurons during emergence from propofol anesthesia in neurosurgical patients

This study records single neuron activity in humans during emergence from propofol anesthesia, showing increased firing rates and shifts in brain activity patterns in medial temporal regions before motor response to verbal command.

Exercise enhances hippocampal-cortical ripple interactions in the human brain

This study shows that a single exercise session increases hippocampal ripples and enhances their coupling with cortical networks in humans.

Reading specific memories from human neurons before and after sleep

This paper develops a transformer model to decode specific memories from human neuronal activity before and after sleep, finding differential contributions from brain regions.

Dexmedetomidine produces more sleep-like brain activity compared to propofol

This study compares brain activity during dexmedetomidine and propofol anesthesia to natural sleep using iEEG, finding dexmedetomidine more similar to sleep in certain metrics.

Human insula neurons respond to simple sounds during passive listening

The paper reports single neuron responses in the human insula to simple sounds during passive listening, showing frequency tuning and shorter response durations compared to auditory cortex.

Traveling waves shape neural population dynamics enabling predictions and internal model updating

The paper shows that traveling waves in the brain carry prediction signals and mismatch information, enabling trial-by-trial updates of predictive models.
