The brain area pinpointed is known to be intimately involved in some of the most advanced planning and decision-making processes that we think of as being especially human.
'We tend to think that being able to plan into the future, be flexible in our approach and learn from others are things that are particularly impressive about humans. We've identified an area of the brain that appears to be uniquely human and is likely to have something to do with these cognitive powers,' says senior researcher Professor Matthew Rushworth of Oxford University's Department of Experimental Psychology.
MRI imaging of 25 adult volunteers was used to identify key components in the ventrolateral frontal cortex area of the human brain, and how these components were connected up with other brain areas. The results were then compared to equivalent MRI data from 25 macaque monkeys.
This ventrolateral frontal cortex area of the brain is involved in many of the highest aspects of cognition and language, and is only present in humans and other primates. Some parts are implicated in psychiatric conditions like ADHD, drug addiction or compulsive behaviour disorders. Language is affected when other parts are damaged after stroke or neurodegenerative disease. A better understanding of the neural connections and networks involved should help the understanding of changes in the brain that go along with these conditions.
The Oxford University researchers report their findings in the science journal Neuron.
Professor Rushworth explains: 'The brain is a mosaic of interlinked areas. We wanted to look at this very important region of the frontal part of the brain and see how many tiles there are and where they are placed.
'We also looked at the connections of each tile -- how they are wired up to the rest of the brain -- as it is these connections that determine the information that can reach that component part and the influence that part can have on other brain regions.'
From the MRI data, the researchers were able to divide the human ventrolateral frontal cortex into 12 areas that were consistent across all the individuals.
Answer:
d) all of these: nominated by the president, confirmed by the U.S. Senate, and appointed for an indefinite period providing they maintain "good behavior."
Explanation:
Federal judges, who are the ones that are that preside over the Supreme Court proceedings and evaluate laws, are indeed nominated by the President, by the U.S. Senate, and appointed for an indefinite period providing they maintain "good behavior" or until they decide to retain, as Article II, Section 2 of the U.S. Constitution provides:
<em>he (The President) </em><em>shall nominate</em><em>, and by and </em><em>with the advice and consent of the Senate</em><em>, shall appoint ambassadors, other public ministers and consuls, </em><em>judges</em><em> of the Supreme Court, and all other officers of the United States.</em>
And as Article III, Section 1 of the U.S. Constitution states:
<em>The judges, both of the supreme and inferior courts, shall hold their offices during good behavior</em>
With this latter provision, the Constitution guarantees that judges make decisions and evaluate statutes according to what is right under the law, and not according to popular's opinion or political pressure. This way, judges don’t have to fear that they will be fired if they make an unpopular decision.
Answer:
Directional selection; stabilizing selection
Explanation:
- The stabilizing selection is a result of the decrease of the population and causes genetic variation due to the natural selection.
- The directional selection of the genetic variation shifts to a new phenotype and on exposure to the environmental changes and both of these can lead to the natural selection and contribute to the variation of the population.
Answer:
forebrain
Explanation:
the forbrain forms the largest part of the brain because it contains the cerebrum and other brain vesicles.if it sustains damage ,alot of brain activities would be in trouble since it is the largest part.
