Non-Verbal and Verbal P300 of Auditory and Visual Stimuli. (1st Report).

P300 with verbal and nonverbal stimuli in normal hearing adults.

UNLABELLED The P300 results from focusing attention on rare stimuli in the midst of other frequent stimuli; it tests recent attention and memory, both of which depend on discriminating among verbal or nonverbal stimuli. AIM To compare the P300 with verbal and nonverbal stimuli in normal-hearing adults. MATERIAL AND METHOD A prospective study was made of 15 male subjects aged from 22 to 55, ...

Cross-Modal Ranschburg Effects: Examining Within-Sequence Repetitions for Visual-Verbal, Non-Verbal-Visual, and Tactile Stimuli

Long-latency auditory evoked potentials with verbal and nonverbal stimuli.

INTRODUCTION Long-latency auditory evoked potentials represent the cortical activity related to attention, memory, and auditory discrimination skills. Acoustic signal processing occurs differently between verbal and nonverbal stimuli, influencing the latency and amplitude patterns. OBJECTIVE To describe the latencies of the cortical potentials P1, N1, P2, N2, and P3, as well as P3 amplitude, ...

Modality effects in verbal working memory: differential prefrontal and parietal responses to auditory and visual stimuli.

The neural bases of verbal (nonspatial) working memory (VWM) have been primarily examined using visual stimuli. Few studies have investigated the neural bases of VWM using auditory stimuli, and fewer have explored modality differences in VWM. In this study, we used functional magnetic resonance imaging (fMRI) to examine similarities and differences between visual VWM (vis-VWM) and auditory VWM ...

Localizing Pain Matrix and Theory of Mind networks with both verbal and non-verbal stimuli

Functional localizer tasks allow researchers to identify brain regions in each individual's brain, using a combination of anatomical and functional constraints. In this study, we compare three social cognitive localizer tasks, designed to efficiently identify regions in the "Pain Matrix," recruited in response to a person's physical pain, and the "Theory of Mind network," recruited in response ...
