Modality-general and modality-specific processes in hallucinations

Modality specific neural correlates of auditory and somatic hallucinations.

Somatic hallucinations occur in schizophrenia and other psychotic disorders, although auditory hallucinations are more common. Although the neural correlates of auditory hallucinations have been described in several neuroimaging studies, little is known of the pathophysiology of somatic hallucinations. Functional magnetic resonance imaging (fMRI) was used to compare the distribution of brain ac...

Uncertainty in visual and auditory series is coded by modality-general and modality-specific neural systems.

Coding for the degree of disorder in a temporally unfolding sensory input allows for optimized encoding of these inputs via information compression and predictive processing. Prior neuroimaging work has examined sensitivity to statistical regularities within single sensory modalities and has associated this function with the hippocampus, anterior cingulate, and lateral temporal cortex. Here we ...

Modality-Specific and Modality-General Encoding of Auditory and Visual Rhythms

Modality-specific control processes in verbal versus spatial working memory.

Over the past decade, neuroimaging and electrophysiological studies of working memory (WM) have made progress in distinguishing the neural substrates of central executive (CE) functions from substrates of temporary storage subsystems. However, the degree to which CE-related processes and their substrates may be further fractionated is less clear. The present study measured event-related potenti...

Evidence for Modality-Specific Processes in Approximate Numerical Comparison

It has been claimed that a genuinely abstract number representation exists and is capable of representing the numerosity of any set of discrete elements irrespective of whether they are presented in visual or auditory modality. To test whether adults can compare large numerosities crossmodally as accurately as intra-modally, we measured Weber fractions and a point of subjective equality of nume...
