They cover attention; principles of human memory: an integrative clinical neuroscience perspective; executive functions: theory, assessment, and treatment; cognitive communication deficits associated with right hemisphere
brain damage; primary progressive aphasia; dementia: concepts and contemporary practice; cognitive communication disorders of mild traumatic brain injury; and traumatic brain injury.
That leaves the right hemisphere
temporarily dominant--and the unchecked right hemisphere
expresses wishes and fears through vivid, concrete images of people, things, and events that seem completely real while one is dreaming, but that often appear illogical or nonsensical afterwards.
According to a recent study, one reason for this preference is that emotions are primarily processed in the right hemisphere
of the brain, which is linked to the left side of the body.
For example, in the case of vision, we know that what we see on our left is processed by the right hemisphere
of the brain, while what we see on the right is processed by the left hemisphere.
The right hemisphere
is the emotional center of the brain, presiding over autobiographical memory and the processing of negative unconscious emotions (Cozolino, 2010; Schore, 2009).
In birds and other animals studied, there is a highly significant separation of attention, with the left hemisphere being used largely for paying narrow-beam, sharply focused attention to the world for the purpose of manipulation and the right hemisphere
for paying open, sustained, vigilant attention to the world, in order to understand and relate to the bigger picture.
In an experiment studying the brain, researchers found that just like humans, dogs process words they hear in their left hemisphere, and interpret the words in the right hemisphere
. Because they have better hearing than we do as humans (they hear frequency at twice the rate of humans), dogs can pick up the tone of the owner.
Therefore the left hemisphere is dominant in right-handed people, while the right hemisphere
is dominant in left-handed people.
With no option left, doctors removed roughly one-third of the right hemisphere
of the boy's brain which included portions of the brain that manage sensory inputs including sight and sound.
"But people who suffer with more conventional forms of depression generally lose this right hemisphere
The researchers found that teens who received PEERS showed a significant decrease in right hemisphere
activity, and an increase in left hemisphere activity.
