lobe volumes, even after adjusting for age, gender, vascular risk factors and APOE4 (a gene independently linked to smaller brain volumes).
The researchers examined total cerebral volume, frontal
lobe volume, temporal
lobe volume, hippocampal volume and white matter hyper - intensity volume in patients without prior stroke or dementia.
According to a recent Framingham Heart Study, people who experience the heart arrhythmia atrial fibrillation (AF), may also suffer from a smaller brain, specifically reduced frontal
lobe volume.
These morphological differences between radio and X-rays suggest that the relativistic electrons are distributed homogeneously over
the lobe volume, whereas the magnetic field is amplified toward the lobe rim region.

When Thompson's team looked at brain scans of 206 healthy people aged 70 to 80, they found that those with at least one copy of the FTO variant had 8 per cent less
volume in their frontal
lobes and 12 per cent less in the occipital
lobes, compared with their counterparts lacking the variant.

The scientists found that an area in the lower frontal
lobe, the so - called orbitofrontal cortex, exhibited smaller
volumes in the healthy individuals that reported that they have problems with regulating emotions.
Through analysis of high - resolution anatomical magnetic resonance imaging of brain
volumes, taken three times over the two - year study period, the researchers were able to determine that individuals with MCI or Alzheimer's showed greater losses in gray matter
volume in both the basal forebrain and temporal
lobe, compared with cognitively normal controls.
Specifically, males on average had larger
volumes and higher tissue densities in the left amygdala, hippocampus, insular cortex, putamen; higher densities in the right VI
lobe of the cerebellum and in the left claustrum; and larger
volumes in the bilateral anterior parahippocampal gyri, posterior cingulate gyri, precuneus, temporal poles, and cerebellum, areas in the left posterior and anterior cingulate gyri, and in the right amygdala, hippocampus, and putamen.
His team found that people who scored highly on a questionnaire rating distractability had larger than average
volumes of grey matter in a brain region called the left superior parietal
lobe, or SPL (Journal of Neuroscience, DOI: 10.1523 / jneurosci.5864 - 10.2011).
Using a combination of magnetic resonance imaging and an advanced segmentation approach, researchers evaluated the differences in the
volumes of subfields of the hippocampus, the seahorse - shaped region in the brain's medial temporal
lobe.
The sum of metastatic tumor
volume was first calculated from four
lobes of lungs per animal (see Materials and methods), and the lung metastasis per group is presented as tumor
volume (cubic millimeters).
Metastatic tumor burden of each animal was calculated by combining tumor
volumes from four
lobes of lungs.
Importantly, we found the most common finding was that there was no difference in grey matter
volume in individuals who had violent outcomes compared to control populations, even in the prefrontal cortex and temporal
lobes, which have been highlighted in the current study by Darby and colleagues.
Increases in working memory - related activation
volume of 82, 73, 83, and 36 % were observed in the left frontal, right frontal, left parietal, and right parietal
lobes, respectively, for 3 T compared with 1.5 T.
Higher expenditure of energy was associated with larger gray matter
volumes in the parietal, temporal and frontal
lobes, which included the basal ganglia, posterior cingulate and hippocampus.
The supercharger features a new four -
lobe rotor design that promotes quieter and more efficient performance, while its large, 2.3 - liter displacement ensures adequate air
volume at high rpm to support the engine's high - horsepower aspiration.

volume located underneath the west
lobe «hull» houses a lobby, a bookshop, a cafe, and the gourmet restaurant El Muelle run by 2 Michelin star chef Jesús Sánchez.
For the frontal
lobe, we observe a statistically significant association with growth and
volume, with initial evidence suggesting
volume, rather than growth, has a stronger influence on externalizing symptoms for low SES children (
volume β = − 0.000158, p =.049; growth β = − 0.00138, p =.045).
Given the importance of the frontal
lobe in behavioral regulation [50], we also hypothesized that variations in this brain area (both in regards to lower
volume and slower growth) would be related to greater disruptive behavioral problems in children (as measured by the Child Behavior Checklist, CBCL).
