This study reveals that the ventral cortex processes visual words with distinct neural patterns. These findings suggest reading relies on sublexical orthographic representations, similar to other visual recognition skills.
Area of Science:
- Neuroscience
- Cognitive Science
- Psychology
Background:
- The ventral cortical network plays a key role in visual word processing.
- The exact properties and selectivity of this network for orthographic stimuli are debated.
Purpose of the Study:
- To investigate how orthographic stimuli elicit distinct activation patterns in the human cortex.
- To determine the selectivity and discriminability profile of the ventral cortex for visual word processing.
Main Methods:
- Pattern-based analyses applied to functional magnetic resonance imaging (fMRI) data.
- Multivariate mapping and multi-voxel pattern classification techniques were employed.
Main Results:
- Words, compared to false-font strings, showed extensive sensitivity in the ventral cortex.
- Distinct pseudowords were encoded by unique neural patterns, indicating identity-level encoding.
- Both pseudoword and face identification utilized shared neural resources within the ventral cortical network.
Conclusions:
- The left ventral cortex is involved in processing orthographic stimuli.
- Evidence supports the existence of sublexical orthographic representations.
- Reading shares continuity with other visual recognition skills.

Higher Mental Functions of the Brain: Language
Language formation and comprehension take place in the dominant hemisphere. The dominant hemisphere is responsible for understanding the meaning of spoken, written, or sign language, as well as the ability to communicate. For most people, the left hemisphere is the dominant one. The right hemisphere, then, gives tone and emotional context to the...

These technologies include computerized axial tomography (CAT or CT scans), positron-emission tomography (PET scans), magnetic resonance imaging (MRI), functional magnetic resonance imaging (fMRI), and Transcranial Magnetic Stimulation (TMS).

Motor Areas
The motor areas located in the frontal lobe are central to controlling voluntary movements. This region is further subdivided into the primary motor cortex and the premotor cortex.
