In what sense does a large language model (LLM) have knowledge? We answer by granting LLMs ‘instrumental knowledge’: knowledge gained by using next-word generation as an instrument. We then ask how instrumental knowledge is related to the ordinary, ‘worldly knowledge’ exhibited by humans, and explore this question in terms of the degree to which instrumental […]

How do passing moments turn into lasting memories? Sheltered from external tasks and distractions, sleep constitutes an optimal state for the brain to reprocess and consolidate previous experiences. Recent work suggests that consolidation is governed by the intricate interaction of slow oscillations (SOs), spindles, and ripples – electrophysiological sleep rhythms that orchestrate neuronal processing and […]

BackgroundVibration of one limb affects motor performance of the contralateral limb, and this may have clinical implications for people with lateralized motor impairments through vibration-induced increase in cortical activation, descending neural drive, or spinal excitability.ObjectiveThe objective of this study was to evaluate the effects of acute biceps brachii tendon vibration on force steadiness and motor […]
