Source: Laboratories of Sarah I. Gimbel and Jonas T. Kaplan— University of Southern California Understanding language is one of the most complex cognitive tasks that humans are capable of. Given the incredible amount of possible choices when combining individual words to form meaning in sentences, it is crucial that the brain is able to identify when words form coherent combinations and when an anomaly appears that undermines meaning. Extensive research has shown that certain scalp-recorded...

In two-dimensional incompressible fluid flow, the continuity equation is essential for ensuring mass conservation, meaning that any change in fluid entering or exiting a region is balanced by a corresponding change elsewhere. For incompressible flow, where density remains constant, this requirement simplifies to the condition that the divergence of the velocity field must be zero. Mathematically, this is expressed as, where u and v represent the horizontal and vertical velocity components,...

Interaction between Phonological and Semantic Processes in Visual Word Recognition using Electrophysiology

We present a protocol to explore the relative activation sequence of phonology and semantics in visual word recognition. The results show that consistent with interactive accounts, semantic and phonological representations may be processed interactively, and higher-level linguistic representations may affect early processing.

Using event-related EEG potentials (ERPs), we investigate the effects of antipsychotic medications on abnormal semantic brain activations in healthy individuals with schizotypal traits. We use ERPs to track distinct changes in brain activity, shedding insight into the cognitive processes associated with semantic categorization.

It treats semantic processing as a sequence of linked stages rather than a single event. Early processing represents perceptual features, and later stages integrate those features into richer semantic representations. Because sensory information unfolds over time, coordinated activity across temporal-lobe and broader cortical networks can progressively refine what is being perceived, recognized, or understood.
Temporal ordering helps researchers determine when information changes from relatively basic perceptual content into integrated meaning. Examining successive neural responses can reveal how the brain updates an interpretation as additional sensory information arrives. This perspective is especially relevant when studying language comprehension, object recognition, and scene recognition, where meaning develops across unfolding input.
The framework links processing across temporal-lobe regions with activity in broader cortical networks. This coordination supports the transition from individual perceptual features to more integrated semantic representations. Studying the networks together can therefore show how meaning depends on distributed neural activity, rather than treating semantic processing as the product of one isolated brain area.
These methods provide ways to characterize neural activity associated with processing as information unfolds. EEG and MEG are particularly useful for examining the timing of neural responses, while neuroimaging can help relate processing to activity across temporal-lobe and broader cortical networks. Used together conceptually, these measurements connect response timing with the neural systems supporting meaning.
A study can present sensory information that unfolds over time, measure the resulting neural responses, and examine how activity changes across successive processing stages. Researchers then relate early responses to perceptual features and later activity to increasingly integrated semantic representations. This workflow can be applied to tasks involving language, objects, scenes, or memory.
It can help investigators ask how meaning emerges during language comprehension, object recognition, and scene recognition, as well as how semantic processing interacts with memory. The same framework also supports research on communication and cognitive disorders by examining whether disruptions in temporal processing alter the progression from sensory analysis to integrated meaning.
