The cortical locus of dream generation could be lateralized to the right or left hemisphere, or be bilaterally represented with either equal or unequal contributions from each hemisphere. In this paper we review the neurological literature for cases of loss or alteration of dream report after brain damage. The distribution of lesion sites is used to test the various hypotheses concerning the la...

This study analysed the relationships among arm coordination symmetry, motor laterality and breathing laterality during a 100-m front crawl, as a function of expertise. Ten elite swimmers (G1), 10 mid-level swimmers (G2), and 8 non-expert swimmers (G3) composed three skill groups, which were distinguished by velocity, stroke rate, stroke length, breathing frequency (BF) and the mean number of s...

Acoustic analysis of laterality in speech sounds poses numerous obstacles to researchers. Spectral characteristics of such segments vary depending on their phonetic context and shaping of the vocal tract [1]. There are no unambiguous acoustic parameters indicating that a sound is produced laterally. The main alternatives to spectrographic analysis in studying laterality are costly devices, such...

Laterality for the processing of melody and timbre was investigated in 64 right-handed non-musicians. In one block of dichotic-listening trials, participants listened for a prespecified target melody, and in a second block they listened for a prespecified target instrument. Females were more accurate on the left ear in the melody task (whereas males tended to show no ear advantage), but there w...

The body-plan of vertebrates, while exteriorly essentially symmetric along its medio-lateral plane, displays numerous left-right differences in the disposition and placement of internal organs. Such left-right asymmetries, established during embryogenesis, are controlled by complex epigenetic and genetic cascades that impart laterality information to the different embryo structures and organ pr...
