Ashby and colleagues [11] argue that positive affect is associated with an increased brain dopamine level in a variety of dopaminergic structures, among them the mesocorticolimbic system, prefrontal cortex and anterior cingulate cortex.
This effect was paralleled by an increased brain accumulation of PrPSc at 90 days post inoculation, but not at the terminal stage of the disease.
The results of this study indicate that there is an increasing trend in brain cancer mortality rates in the rural Serrana Region in Brazil.
The results of this study indicated that there was an increasing trend in brain cancer mortality over time among adults living in an agricultural area in the state of Rio de Janeiro.
There is an increasing interest in analyzing brain FC alterations using graph theoretical approaches.
Furthermore, there is an increased secretion of brain-derived neurotrophic factor (BDNF), a protein crucial for new learning that occurs during anodal stimulation (Fritsch et al., 2010).
A growing body of evidence indicates that there is an increased oxidative stress in AD brains and it is hypothesized that nitric oxide (NO) can be related to many of the pathophysiological mechanisms of AD (Akomolafe et al. 2006; Moreira et al. 2008).
It is often assumed that increasing brain size was a general evolutionary trend in primates, yet recent fossil discoveries have documented brain size decreases in some lineages, raising the question of how general a trend there was for brains to increase in mass over evolutionary time.
There was an increased risk of brain/spinal tumours among children exposed around or soon after birth to higher levels of community infections, in particular measles (OR for trend=2.1, 95%CI : 1.3 3.6, P=0.008) and influenza (OR for exposure=3.3, 95%CI : 1.5 7.4, P=0.005).
Many experts had previously believed that intelligence had developed before bipedalism, that in fact it was an increase in brain size that had driven the development of tools and, so that the arms were free to make and use them, a need to walk on two legs.
