2018年4月19日 · It consists of the region around the lateral sulcus (Sylvian fissure) of the left hemisphere and includes Broca’s area and Wernicke’s area. Damage to the zone causes various forms of aphasia. Also called perisylvian area; perisylvian language area.

Perisylvian syndrome is a rare neurological disease characterized by damage to the sylvian fissure (lateral sulcus), an area in the brain involved in language and speech. The main symptoms are difficulty chewing and swallowing, low muscle tone in the face and tongue, speech and language development disorders , and epilepsy .

However, the heterogeneous clinical presentations of conduction aphasia suggest a greater complexity of perisylvian anatomical connections than allowed for in the classical anatomical model. This article re-explores perisylvian language connectivity using in vivo diffusion tensor magnetic resonance imaging tractography.

2012年11月1日 · Johann Christian Reil was the first to identify a group of fibres running deeply in the white matter of the temporal, parietal, and frontal regions around the Sylvian fissure, which he described as the Ungenannte Marksubstanz (unnamed white matter) (Figure 7.1A) (Reil, 1812).

2017年10月1日 · Aiming at exploring the brain’s structural organisation underlying successful second language learning, we investigate the anatomy of the perisylvian language network in a group of healthy adults, consisting of participants with …

We recruited 101 healthy right-handed subjects aged 9–40 years to investigate age-related differences in the anatomy of perisylvian language pathways and 86 adult twins (52 monozygotic and 34 dizygotic) to understand how heritability factors influence language anatomy.

2004年12月13日 · The Function of Direct and Indirect Perisylvian Pathways. Our study suggests a greater complexity of connectivity between frontal and temporal language regions than previously supposed, allowing for a variety of distinct disconnection syndromes not predicted by the classical arcuate model.

In this experiment, we evaluated cognitive control in bilinguals relative to monolinguals by using a dimensional overlap model to predict performance in a task composed of Stroop and Simon stimuli.

perisylvian language zone the area of the brain that is responsible for language. It consists of the region around the lateral sulcus (Sylvian fissure) of the left hemisphere and includes Broca’s area and Wernicke’s area. Damage to the zone causes various forms of aphasia. Also called perisylvian area; perisylvian language area.

Homologous neural networks seem to exist in the human left and right hemispheres tightly linking cortical regions straddling the sylvian fissure.
