“…These authors further reported that among individuals who had this structure it was, on average, 53.3% larger in females compared to males despite the fact that male brains were larger than females. In contrast, another post-mortem study by Park et al (1993) reported that the ITA was absent in only 11.6% of the 146 individuals examined, but sex differences were not investigated.…”

The interthalamic adhesion (ITA) is an understudied neuroanatomical structure that forms a bridge of tissue connecting the thalamus of each hemisphere across the midline whose functional significance remains largely unknown. The likelihood of ITA absence has been reported in some studies to be increased in males, but findings have been inconsistent. We used magnetic resonance imaging to investigate the size and absence of the ITA and their relationship to thalamic volume, putative indices of white matter integrity (fractional anisotropy and mean diffusivity) within the anterior thalamic radiation and neuropsychological functions in 233 (129M/104F) healthy volunteers (age range = 8 to 68). To ensure high reliability in this study 2 operators independently rated the absence of the ITA and measured its size for all individuals. The ITA was absent in 4% of all individuals with no sex differences in its absence. Females had greater ITA size compared to males overall with both groups demonstrating nonlinear age-associated changes across the age range examined. ITA size among females correlated significantly with thalamus volume and lower mean diffusivity in the anterior thalamic radiation. Path modeling indicated that ITA size statistically mediated the relationship between age and attention among females. Our findings provide evidence for sex differences in ITA size across the lifespan, which are associated with the surrounding thalamic anatomy and neuropsychological functions.

“…1) based on one single model. These locations were noted as the different types of site variations for the interthalamic adhesion found in humans by Park et al (1993). All the models were meshed with unstructured tetrahedral elements using Ansys CFX (version 11, Ansys Inc., Canonsburg, USA).…”

“…In contrast, a large cadaveric investigation of 921 cases revealed a 31.70% lack of ITA in various age groups (30). Another cadaveric study by Park et al on Korean brains reported ITA absence in 11.60% (28). Even fewer Japanese brains lacked an ITA (5.80%) (35).…”

AIM:To determine the prevalence, location, and dimensions of interthalamic adhesions (ITAs) in Indian brains. MATERIAL and METHODS:We examined 100 brains (50 cadaveric and 50 MR images) in the midsagittal plane for the presence or absence of ITAs, their location in the lateral wall of the third ventricle and dimensions. RESULTS:ITA was found in 87 brains (87%), four showed duplication (4%). Both its duplication and absence were more frequent among males than in females. It was most commonly located in the anterosuperior quadrant with posterosuperior extension. The mean horizontal diameter (7.13 ± 4.31 mm) was longer than the vertical (5.13 ± 3.17) in all the brains. Its average area (37.98 ± 41.47 mm 2 ) showed tremendous variation (ranges between 4.40 mm 2 to 203 mm 2 ) and was significantly higher in females (61.23 ± 56.22 mm 2 ) than males (36.44 ± 43.21 mm 2 ) (p=0.026). No correlation was found between the surface area of the ITA and the length of the third ventricle. CONCLUSION:Absence and duplication of ITA are fairly common in Indian brains with significant male predominance. Morphometric data are robust to advocate for sex differences in the ITA size, although not associated with surrounding thalamic or third ventricle anatomy.
