A lateralized distribution of neuropeptidase activities in the frontal cortex of normotensive and hypertensive rats has been described depending on the use of some vasoactive drugs and linked to certain mood disorders. Asymmetrical neuroperipheral connections involving neuropeptidases from the left or right hemisphere and aminopeptidases from the heart or plasma have been suggested to play a role in this asymmetry. We hypothesize that such asymmetries could be extended to the connection between the brain and physiologic parameters and metabolic factors from plasma and urine. To assess this hypothesis, we analyzed the possible correlation between neuropeptidases from the left and right frontal cortex with peripheral parameters in normotensive (Wistar Kyoto [WKY]) rats and hypertensive rats (spontaneously hypertensive rats [SHR]) untreated or treated with vasoactive drugs such as captopril, propranolol and L-nitro-arginine methyl ester. Neuropeptidase activities from the frontal cortex were analyzed fluorometrically using arylamide derivatives as substrates. Physiological parameters and metabolic factors from plasma and urine were determined using routine laboratory techniques. Vasoactive drug treatments differentially modified the asymmetrical neuroperipheral pattern by changing the predominance of the correlations between peripheral parameters and central neuropeptidase activities of the left and right frontal cortex. The response pattern also differed between SHR and WKY rats. These results support an asymmetric integrative function of the organism and suggest the possibility of a different neurometabolic response coupled to particular mood disorders, depending on the selected vasoactive drug.

Within the present paper, we attempted to study specific features of inhibitory control in junior schoolchildren with the handedness of the different types. assessment of inhibitory control was fulfilled with the help of the method of recurrent biological feedback. The assessment of the type of handedness was performed through the set of tasks. resistance of inhibitory processes and stress resistance were identified in the right-handed children compared to the left-handed and mixed-handed children. This study might be useful in the area of psychophysiology of individual differences in children. Despite the abundance of literature on the study of executive functions, there is still no understanding of how inhibitory processes develop in the ontogenesis of children with different lateral preferences.

“…The Fifth International Luria Memorial Congress mix-handed would be in the range from -5 to +5; right-handed would be in the range from +5 to +100 [28]. These possible ranges would produce a reduced number of children with symmetric handedness indicators because the range for dominant lateral indicators is higher than for the symmetric ones.…”

The purpose of the research was to compare different methods of handedness assessment. Participants included 161 children between 4 and 7 years of age: 87 girls and 74 boys. The research incorporated typical methods used in investigations and assessment of lateral phenotype. All tests were repeated at least three times to assess their reliability in assessing children. Our findings reveal that different sets of assessments and scoring methods produced different results in determination of right- or left-handedness. Factor analysis identified three significant factors of handedness: social pressure, genetic mechanisms, and two-hand coordination. We conclude that it is necessary for assessment of handedness to use at least three testsassociated with each of these factors. Keywords: handedness, left-handedness, methods, lateral profile, children.
