Neural correlates of vibrotactile working memory in the human brain.
Recent neurophysiological studies in macaques identified a network of brain regions related to vibrotactile working memory (WM), including somatosensory, motor, premotor, and prefrontal cortex. In these studies, monkeys decided which of two vibrotactile stimuli that were sequentially applied to their fingertips and separated by a short delay had the higher vibration frequency. Using the same ta...
متن کاملOscillatory correlates of vibrotactile frequency processing in human working memory.
Previous animal research has revealed neuronal activity underlying short-term retention of vibrotactile stimuli, providing evidence for a parametric representation of stimulus frequency in primate tactile working memory (Romo et al., 1999). Here, we investigated the neural correlates of vibrotactile frequency processing in human working memory, using noninvasive electroencephalography (EEG). Pa...
متن کاملThe neural correlates of human vibrotactile working memory: Converging evidence from functional magnetic resonance imaging, electroencephalographic and behavioral studies
The present dissertation aimed to shed more light on the psychological mechanisms and the neural basis of tactile working memory (WM). For this purpose, a vibrotactile delayed discrimination task was studied using the methods of functional magnetic resonance imaging (fMRI), electroencephalography (EEG), concurrent subliminal electrical stimulation and psychophysics. The fMRI study (Study I) sho...
متن کاملNeural correlates of consolidation in working memory.
Many of our daily activities rely on a brain system called working memory, which implements our ability to encode information for short-term maintenance, possible manipulation, and retrieval. A recent intracranial study of patients performing a paradigmatic working memory task revealed that the maintenance of information involves a distributed network of oscillations in the gamma band (>40 Hz)....
متن کاملBrain oscillatory correlates of working memory constraints.
It has been claimed that the coordination of neuronal oscillations differing in frequency is relevant for cognition. However, the validity of this claim has scarcely been investigated. Recent studies revealed that cross-frequency phase coupling and modulations of alpha-power dissociate between retention of relevant and suppression of irrelevant information in visual working memory (WM). We summ...
