of those with and without autism displayed comparable amygdala volume and brain-cell size, Schumann and Amaral report in the July 19 Journal of Neuroscience.
Graphic organizers work because they visually represent linear ideas and are beneficial to both left and right hemispheres of the brain
The absence of effects in the heart, a tissue that, like the brain
, has high oxygen demand, could imply that only the brain
is targeted by ETS exposure, or alternatively that the heart may show similar effects but with a different temporal relationship.
Wrap up the lesson by discussing the following questions: How does the flood of dopamine in the brain
that toluene apparently causes seem to affect the behavior of individual people who abuse inhalants?
They had developed problems with the striatum, a part of the brain
associated with control of movement, attention, motivation, and reward.
Such experiences fed Hawkins' convictions that intelligent machines must be more genuinely brain-like, and that making them so requires a new theory of how the brain
By studying the brain
pathways of the visual and motion response systems, Bakardjian was able to isolate a brain signal for motion that occurs only 100 milliseconds after visual stimulation.
Among the most widely used is functional magnetic resonance imaging, which makes it possible to map activity in the brain
while a subject is performing a specific task, such as counting backward from 10 or identifying different colors.
In short, enough scientific evidence exists to cast doubt on the standard definition of brain death as the irreversible absence of all functions of the brain
The early promising results of such techniques in understanding both normal and aberrant workings of the brain
have given powerful impetus to further research.
By exploring the brain
activities associated with religious feelings, neurotheology asks some fundamental questions about the nature of religious experience.
A brain scan revealed diffuse swelling of the brain
and a small subdural hematoma.
These range from the acute response of the brain
to trauma to the long-term consequences of frontal or temporal lobe damage in a child or adult.
Tourtellottee ticks them off: the discovery that patients with Parkinson's disease lack dopamine, a chemical messenger that transmits nerve cell signals in the brain
, which led to the development of a new therapy; the finding that there is a 90% decrease in chlorine acetyltransferase in the brains
of Alzheimer's disease patients; the disclosure of certain immune T cells in the inflammatory lesions in the brains
of MS patients, linking the cells with active extension of the lesion; and the finding of measles virus in the brains
of MS people (as well as in some healthy persons).
Just as crunches and kick-boxing tone abs and increase cardio strength, programs offered at the brain
fitness center target and help train essential core mental muscles to improve memory, concentration, stress management, and decision-making skills.
