Computer simulations explain the limitations of working memory

... (fMRI) has revealed that the frontal and parietal lobes are activated when a sequence of two pictures is ... to suggest in their article that the frontal lobes might be able to regulate the memory capacity of ... that increased activation of the frontal lobes will improve working memory," continues Dr Edin. ...

Like eavesdropping at a party

... protein, explains Yue, is made of two ball-like lobes, and it's these two lobes that act as the different calcium-sensing "ears." The C lobe listens ... globally, across the whole cell. To figure out how calmodulin's two lobes can sense different sources of calcium, the team took a two-pronged ...

Swine flu: What does it do to pigs?

... seen by the naked eye were observed. According to Thanawongnuwech, "These lesions were characterized by dark plum-colored, consolidated areas on lung lobes and were most severe two days after infection, especially in the H1N1-infected pigs, where approximately a third of the lung was covered". The course ...

£2 million study to reveal workings of dementia genes

... award from the Medical Research Council. Frontotemporal lobar degeneration (FTLD) is a group of dementias that affect the frontal and temporal lobes of the brain and are characterised by behaviour and language dysfunction, rather than the memory loss associated with Alzheimer's disease (AD). ...

Odd protein interaction guides development of olfactory system

... way. The receptor is actually regulating the ligand. The researchers made this discovery when they compared the development of normal antennal lobes to those that formed when Wnt5 or derailed were missing, present at very low levels, or present at extremely high levels. When Wnt5 was absent, ...

Endobronchial valve significantly improves emphysema

... of treated patients, the results were even more dramatic, Dr. Sciurba added. For example, patients who had a fissure completely separating the lobes of the lung and whose endobronchial valves were placed to exclude the entire diseased lobe had changes in FEV-1 of greater than 20 percent, he said. ...

Memory loss affects more of the brain than previously thought

... functionality in both the frontal and temporal lobes of the brain. Previous studies looking at ... "Involvement of both the frontal and temporal lobes in the earliest stages of AD suggests the ... level of activation in the posterior frontal lobes (during retrieval). "These findings suggest ...

Brain activity related to processing faces is similar in people with, without autism

... with a deficit in "executive function" in portions of the brain's frontal lobes than with a selective deficit in the brain's processing of information from faces. These portions of the frontal lobes are where "executive" tasks, such as sifting through complex information, ...

Stroke study sheds light on left-right brain divide

... who most frequently failed to spot their errors and had difficulty keep track of the changing task rules. The group with damage to the left frontal lobes corrected 68% of mistakes in the test, whereas people with right-brain damage only made corrections to 30% of their errors. This suggests that people ...

Imaging pinpoints brain regions that 'see the future'

... that the neural network underlying future thought is not isolated in the brain's frontal cortex, as some have speculated. Although the frontal lobes play a well-documented role in carrying out future-oriented executive operations, such as anticipation, planning and monitoring, the spark for these ...

Slow brain waves play key role in coordinating complex activity

... procedures, Barbaro removed a portion of each patient's skull and placed a grid of 64 electrodes on the surface of the brain's frontal and temporal lobes to precisely localize the source of the seizure so it could be removed in a subsequent surgical procedure. Knight, Canolty and their UC Berkeley ...

Brain regions do not communicate efficiently in adults with autism

... with language, which is impaired in many people with autism. A global pattern of decreased neural connectivity between the frontal lobes and the rest of autistic brain showed up on the alpha wave band. These findings support several other studies using functional magnetic resonance ...

Cancer stem cells linked to radiation resistance

... cells from the tissue and grew them in cultures in the laboratory. For the second model, they transplanted the glioblastoma tissue into the frontal lobes of the brains of mice. The researchers first measured the number of glioma stem cells present in the original tissue and then administered set ...

Smoking changes brain chemistry

... Reduced choline levels can be a precursor to the breakdown of cell membranes. Concentration of total creatine (tCr) levels in the frontal lobes was typically higher in the smokers who did not use patches compared to those who did. The metabolite tCr plays an important role in supplying energy ...

Sleeping sickness parasite shows how cells divide their insides

... from the basal body, involved in the duplication of the Golgi apparatus and defined by a highly-conserved protein, Centrin2. This structure has two lobes -- one at the old Golgi, the other where the new Golgi forms. Once a new Golgi has grown, the Centrin structure itself duplicates so that two ...

Cellular Defects in Premature Aging Disease are Reversible

... lamin A protein had been eliminated and more than 90 percent of progeria cells were restored to normal; visually, the nuclei lost their wrinkles and lobes and returned to a natural ellipsoid shape, and the expression of other nuclear proteins was also restored to normal levels. "It's amazing that we ...
