Emergent smartphone temporal structures reflect cognitive constraints

This study shows that cognitive constraints measured in speeded tasks influence long-term smartphone temporal patterns, revealing how cognitive processes shape naturalistic behavior.

Bursts of regional cortical inhibition during smartphone use

This study examines beta-bursts during smartphone use, finding that bursts precede touchscreen interactions and are spatially localized to sensorimotor regions.

Cortical integration of tactile inputs distributed across timescales

The paper investigates how tactile inputs are integrated across different timescales using EEG recordings and finds that early and late cortical stages are influenced by preceding intervals, while intermediate stages are influenced by both previous and penultimate intervals.

Smartphone behavior is suppressed during bursts of wake slow waves

The paper examines how bursts of wake slow waves correlate with reduced smartphone interaction probability, suggesting cortical silencing structures behavioral output timing.

Behavioral maps organize smartphone interactions in the brain

The paper shows that smartphone interactions are organized by recurring neural patterns linked to behavioral intervals, suggesting the brain uses shared neural structures for diverse actions.

Neural microstates in real-world behaviour captured on the smartphone

The paper investigates how neural microstates relate to real-world smartphone behavior, finding that resting microstates correlate with long-term behavioral patterns but do not directly respond to momentary behavioral fluctuations.

Age-related behavioral resilience in smartphone touchscreen interaction dynamics

The paper uses smartphone touchscreen interaction data to infer aging states and finds individuals exhibit fluctuating age-related behavioral resilience over time.

Neural processing of goal and non-goal-directed movements on the smartphone

The paper analyzes neural signals during goal-directed and non-goal-directed smartphone touch movements, finding distinct neural processing patterns for each.

Multiple forms of neural processing when repeating voluntary thumb flexions

The paper analyzes EEG signals from repeated thumb flexions to show trial-to-trial variability in neural processing patterns, revealing distinct activation patterns rather than noise.

Striatal dopamine synthesis capacity reflects smartphone social activity

The paper links striatal dopamine synthesis capacity to smartphone social activity using PET scans and behavioral data from healthy adults.

Smartphone deprivation alters cortical sensorimotor processing of the hand

This study shows that cortical sensorimotor processing of the hand changes after smartphone deprivation, affecting tapping speed, thumb reaction times, and EEG responses.

Large cognitive fluctuations surrounding sleep in daily living

This study uses smartphone data to show that cognitive output fluctuates around sleep, differing from physical activity rhythms and being worse during sleep periods.
