By the 19th century Polish was well established both as a literary vehicle and as the dominant language of common speech in Poland, despite attempts of the partitioning powers to Germanize or Russify the population.
Most people are right-handed and left-cerebrally dominant for speech, leading historically to the general notion of left-hemispheric dominance, and more recently to genetic models proposing a single lateralizing gene.
Orton argued that a failure to develop a dominant language hemisphere led to difficulties with speech, language and reading.
The frequency response of the complete filterbank, i.e. the sum of the responses of the nine individual filters, is shown in Figure 2. Due to the spacing of the centre frequency of the filters and the overlap of their transfer functions, we effectively give more weight to the modulation frequencies that are dominant in speech [30].
All participants were left-hemisphere dominant for speech production as determined by a previous fMRI study (R.H., A.P.L., J.C.R., C.J.P., and J.C., unpublished data).
One hemisphere, usually the left, is functionally dominant, controlling language and speech.
In speech dominant segments it is then desirable to have less noise reduction to avoid speech distortion, while in noise dominant segments it is desirable to have as much noise reduction as possible.
In most people the left brain is dominant and controls speech, so there have been lingering questions about how well Ms. Giffords will ultimately be able to speak and understand language.
The frontal lobe, which lies rostral to the central sulcus, is involved with many of the components of intelligence (foresight, planning, and comprehension), with mood, with motor activity on the opposite side of the body, and (in the case of the dominant hemisphere) with speech production.
This finding suggests a group-specific impairment of the speech dominant left hemisphere.
