New preprint out! In this opinion paper, we review our recent work showing that frontal beta frequency shifts signal categorical decisions. We propose that the observed frequency modulations emerge from the recruitment of distinct neural ensembles when different (categorical) decisions are made.

Beta frequency shifts in decision making: Spectral fingerprints or communication channels?
Recent evidence suggests that beta-band activity plays a key role in decision-making. Here we review our recent work in humans and non-human primates showing that beta-band frequency shifts in frontal...

Another paper out! New research from our lab explores how beta-band activity signals decisions. We show that subtle shifts in beta-band *frequency* signal categorical decision outcomes — a neural signature that generalizes across tasks and species. ➡️

Beta-band frequency shifts signal decisions in human prefrontal cortex
Beta-band synchronization has been found to be content-specific, particularly during decision-making. Recently, we showed a beta-band frequency shift in macaque prefrontal cortex to reflect categorica...

Distinct alpha networks modulate different aspects of perceptual decision-making
Fluctuations in alpha-band neural oscillations influence whether we perceive faint stimuli, but how these oscillations relate to different perceptual processes is not clear. This study shows that alph...

Low alpha power boosts faint stimulus detection—but how? 🤔 After much head-scratching, we took a network approach and found that different alpha networks play distinct roles: the visual alpha network tunes perceptual sensitivity, while the sensorimotor alpha network shapes decision criteria. 🧠✨

Distinct Alpha Networks Modulate Different Aspects of Perceptual Decision-Making
Why do we sometimes perceive a faint stimulus but miss it at other times? One explanation is that conscious perception fluctuates with the brains internal state, influencing how external stimuli are p...

New paper out!

We asked whether neural mechanisms for time estimation are similar in monkeys and humans. We compared ERPs during a temporal bisection task, in which participants had to determine whether the duration of a time interval was longer or shorter than a prototype.

Common neural mechanisms supporting time judgements in humans and monkeys
There has been an increasing interest in identifying the biological underpinnings of human time perception, for which purpose research in non-human primates (NHP) is common. Although previous work, ba...
