Specifically, as with the frontal lobes
, the normal "right greater than left" asymmetry of the caudate appears to be absent in children with ADD compared to normal children.
Previous studies had found that, when given the same task, adults label most fearful expressions correctly and exhibit much more activity in the frontal lobes
than in the amygdala.
0 cm was noted in the region of the pituitary gland and inferior surface of the frontal lobes
Fibers project from the frontal lobes
to a number of subcortical structures, including the caudate nucleus and putamen (Beritoff, 1971; DeVito & Smith, 1964; Kitai, Kocsis, Preston, & Sugimori, 1976; Leonard, 1969; Nauta, 1964; Selemon & Goldman-Rakic, 1985; Webster, 1965), globus pallidus (Beritoff, 1971; DeVito & Smith, 1964), and substantia nigra (Beritoff, 1971; DeVito & Smith, 1964).
Damage to the frontal lobes
means that people are more reckless, they are less socially-inhibited, they behave in a less predictable way," said Dr Morgan.
Beer's research looks at the part of the frontal lobes
involved in social comparisons and what is known as the "above-average effect.
For the FDDNP scans, the researchers quantified regional binding in the medial and lateral temporal lobe, the parietal lobe, the frontal and prefrontal areas of the frontal lobe
, and the cerebellum (the control region).
Maturation of the frontal lobes
may be required for dreams with a narrative structure, in his view.
In healthy people, the more you activate a portion of your frontal lobes
, the more accurate your view of yourself is," says Jennifer Beer, an assistant professor of psychology, who conducted the research with graduate student Brent L.
Analysis is beginning on coherence data from a new set of subjects to determine whether frontal lobe
activity drives temporal lobe activity, she said.
Pennington, a psychologist at the University of Denver, suggests that in many cases of hard-core delinquency, low verbal IQ scores tap into only a small part of a deeper disruption within the brain's frontal lobes
posterior regions mature first and the frontal lobes
