The percentage (10-13%) of left handedness in human has apparently not changed since the Neolithic. Left handedness is heritable and appears to be repeatedly associated with some reduced fitness components; the persistence of left handedness implies that left handers have a fitness advantage in some situations. We propose that left handers have a frequency-dependent advantage in fights and for ...

The handedness of seventy-five persons without evidence of neurological disease, was assessed with a standardised test. An analysis of the CT scans of the same persons was performed to determine (1) presence and lateralisation of frontal and occipital "petalia," (2) width of frontal and occipital lobes of each hemisphere, (3) direction of straight sinus deviation. Results suggest that handednes...

Pregnancy- and birth-related factors may have an effect on handedness. Compared with singletons, twins have a lower birth weight, shorter gestational age, and are at higher risk for birth complications. We tested whether the prevalence of left-handedness is higher among twins than singletons, and if so, whether that difference is fully explained by pregnancy and birth-related differences betwee...

Non-shared environmental variance (NSEV) accounts for 76% of in genetic modelling handedness. However, it is very misleading to suggest that NSEV, “highlights the importance non-genetic factors ontogenesis hemispheric asymmetries”. NSEV poorly named, calculated only by subtraction, and provides no direct evidence effects sense external environment. Miller suggested would be better named as “res...

The aim of this study is to obtain a Spanish brief version the Pregnancy Related Anxiety Questionnaire and analyse its psychometric properties. A longitudinal was carried out on sample 569 pregnant women with normal risk status. Participants were assessed in first, second, third trimesters pregnancy by using socio-demographic obstetric-gynaecological questionnaire, PRAQ-55, Edinburgh Postnatal ...

It is frequently stated that right-handedness reflects hemispheric dominance for language. Indeed, most right-handers process phonological aspects of language with the left hemisphere (and other aspects with the right hemisphere). However, given the overwhelming majority of right-handers and of individuals showing left-hemisphere language dominance, there is a high probability to be right-hande...

An association between APOE genotype and left-handedness has been previously reported. We examined whether such association exists in a population sample of 4438 unrelated Caucasian adults aged 45-69 years (2022 males and 2416 females). Left-handedness was based on self-reported left-hand dominance for writing (prevalence 4.9%) and on consistently higher left-hand grip strength in two repeated ...

Functional neuroimaging studies of handedness have traditionally focused on exploring regionally activated discrepancies, yet little is known regarding the effect of handedness on functional connections of brain regions. Here, we reported the relationship between cerebellar functional connectivity patterns and handedness by low-frequency blood oxygenation level-dependent fluctuations. Compared ...
