Under 10% chloral hydrate anesthesia, rats were irradiated in brain hemisphere
(right side: n = 6; left side: n = 6) with a highly collimated 6 MV photon beam from a linear accelerator (Primus-M, Siemens, Germany) with a single dose of approximately 30 Gy.
The Mind Mirror is 'a portable ECG machine that could monitor the alpha, beta and theta rhythms from each brain hemisphere
(left and right neo-cortex) simultaneously.
Classical imaging findings include hypoplasia of one brain hemisphere
(hemiatrophy), often with reduced volume of a corresponding cranial fossa, and consecutive thickening of nearby bony structures and enlargement of equilateral paranasal sinuses, the frontal sinus being most often involved [1-3].
The effect is seen during deep "slow-wave" sleep and causes the left brain hemisphere
to be especially sensitive to sound.
The second part addresses implications for learning and teaching, including the network-based, dynamic nature of skill development; pedagogical strategies to support the development of experience-based intuitions; the interdependence of emotion and cognition in poetry writing development; the role of emotion in the learning of two students who had a brain hemisphere
removed to control seizures; the role of mirror neurons; the importance of nonconscious emotional processing in social emotion and the linking of the conscious mind to nonconscious biological regulatory systems; and implications for the design of digital learning technologies.
A theory, brought forth in the 1980s by US neurologists Norman Geschwind and Albert Galaburda, posits that testosterone delays the maturation of the left brain hemisphere
during embryonic development.
He therefore suggested that the left brain hemisphere
controls right hand and vice versa (Pritchard & Alloway, 2000).
The researchers said their findings suggest that personality types have nothing to do with one brain hemisphere
being more active, stronger, or more connected than the other.
Here's how these three factors combine to create a brain hemisphere
ERIC Descriptors: Number Concepts; Numeracy; Cognitive Processes; Arithmetic; Neurology; Brain Hemisphere

is involved here in that the left side appears to move logically in a planned sequence.
Notably, patients with severe, unilateral carotid stenosis showed cognitive impairments for functions linked with the brain hemisphere
that received its blood supply from an occluded carotid, while the same people with an unimpeded contralateral carotid showed no impairment on cognitive tests that tested their contralateral brain function, said Dr.
