“…21 The superior longitudinal fasciculus is strongly related to language and communication pathways. 21 Due to a small sample, we could not establish a statistical correlation between these findings; larger, future studies are needed to address possible relationships.…”

BACKGROUND AND PURPOSE: Individuals born from pregnancies complicated by preeclampsia have an elevated risk for cognitive impairment. Deviations in maternal plasma angiokines occur for prolonged intervals before clinical signs of preeclampsia. We hypothesized that fetal brain vascular and nervous tissue development become deviated during maternal progression toward preeclampsia and that such deviations would be detectable by MR imaging.

“…The SLF III is the ventral component that originates in the supramarginal gyrus and terminates in the ventral premotor and prefrontal cortex. 62,63 The AF is the component that originates in the superi or temporal gyrus, curves around the caudal tip of the Sylvian fissure and terminates in the dorsal prefrontal cortex.…”

“…As a result, we consider the SLF I to be a frontoparietal long association fiber pathway as has been stated in other studies in the literature. 32,34,41,61,65 The most prominent and easily perceived component of the SLF, the SLF II, is located in the middle part of the occipitoparietofrontal region. The SLF II shows right dominance in 65% of cerebra.…”

T he contemporary dual stream language model is analogous to the visual system, which is composed of ventral "what" and dorsal "where" streams. 11,31The ventral language stream is involved in semantic (meaning of word) processing of speech, and the dorsal stream controls phonological (word production) processing of speech. 11,59 The arcuate (AF) and superior longitudinal fasciculi (SLF) are involved in the dorsal language stream, while the middle longitudinal (MLF), inferior longitudinal (ILF), inferior frontooccipital (IFOF), and uncinate fasciculi (UF) are associated with the ventral language stream (see Fig. 3C). 15,18,31,59 This study examined the components of the dorsal language stream (SLF and AF) using postmortem fiber dissection and DTI (diffusion tensor imaging) techniques (Figs. 1-3). These anatomical findings were compared with data from clinical-radiological analysis and intraoperative stimulation of white matter (Table 1).The frontoparietal network, called the SLF, was verified and delineated as the dorsal SLF I, the middle SLF II, obJective The aim of this study was to examine the arcuate (AF) and superior longitudinal fasciculi (SLF), which together form the dorsal language stream, using fiber dissection and diffusion imaging techniques in the human brain. methods Twenty-five formalin-fixed brains (50 hemispheres) and 3 adult cadaveric heads, prepared according to the Klingler method, were examined by the fiber dissection technique. The authors' findings were supported with MR tractography provided by the Human Connectome Project, WU-Minn Consortium. The frequencies of gyral distributions were calculated in segments of the AF and SLF in the cadaveric specimens. results The AF has ventral and dorsal segments, and the SLF has 3 segments: SLF I (dorsal pathway), II (middle pathway), and III (ventral pathway). The AF ventral segment connects the middle (88%; all percentages represent the area of the named structure that is connected to the tract) and posterior (100%) parts of the superior temporal gyri and the middle part (92%) of the middle temporal gyrus to the posterior part of the inferior frontal gyrus (96% in pars opercularis, 40% in pars triangularis) and the ventral premotor cortex (84%) by passing deep to the lower part of the supramarginal gyrus (100%). The AF dorsal segment connects the posterior part of the middle (100%) and inferior temporal gyri (76%) to the posterior part of the inferior frontal gyrus (96% in pars opercularis), ventral premotor cortex (72%), and posterior part of the middle frontal gyrus (56%) by passing deep to the lower part of the angular gyrus (100%). coNclusioNs This study depicts the distinct subdivision of the AF and SLF, based on cadaveric fiber dissection and diffusion imaging techniques, to clarify the complicated language processing pathways.
