In this study, a multivariate model that collectively takes into account the effects of multiple morphological variables, including the cortical thickness, surface area, and curvature index, was used to investigate the hemispheric asymmetry
on a longitudinal database to distinguish MCI converters from nonconverters.
Nevertheless, EDA records have been evaluated in the investigation of diseases such as hemispheric asymmetry
, anxiety, depression and schizophrenia .
Sex hormonal effects on hemispheric asymmetry
and interhemispheric interaction.
They found that high-functioning older adults showed strong bilateral prefrontal activations whereas young subjects involved only a smaller prefrontal circuit in the right hemisphere and proposed that in aging subjects, there could be a Hemispheric Asymmetry
Reduction in Older Adults (HAROLD model) for some cognitive functions.
A point of interest is to what extent this hemispheric asymmetry
of the motor mechanisms is translated into a difference of performance of the two upper limbs.
Hemispheric lateralization, also known as hemispheric asymmetry
, refers to the structural or morphological differences between the right and left hemispheres, as well as the differences in the information processing capacity between the hemispheres .
However, we can only speculate that the mTBI caused the hemispheric asymmetry
, given the lack of an isolated mTBI group.
Gur et al., (1982) showed that the direction and degree of hemispheric asymmetry
of cerebral blood flow are influenced by gender and upper limb preferential use.
Special interest was paid to gray matter and white matter fraction, hemispheric asymmetry
and volumes of the hippocampus, thalamus, caudate and putamen.5
In the old male rats normally nourished or malnourished prenatally, hemispheric asymmetry
was addressed in the CA1 and CA3/CA2 subfields of hippocampal formation (9).
Luca Tommasi and Daniele Marzoli from the University "Gabriele d'Annunzio" in Chieti say that the natural side bias, depending on hemispheric asymmetry
in the brain, manifests itself in everyday human behaviour.
By contrast, other researchers failed to find evidence in favor of the predicted hemispheric asymmetry
, suggesting that the RH and LH have the same ability to manage with global and local information (Alarcon & Blanca, 2000; Alivisatos & Wilding, 1982; Amirkhiabani, 1998; Arnau, Blanca, & Salvador, 1992b; Blanca, 1992; Blanca & Alarcon, 2002; Boles, 1984; Boles & Karner, 1996; Polich & Aguilar, 1990; Van Kleeck, 1989).
