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.
<u>Answer:
</u>
Research shows that the traditional and conservative married couples are, the less interest and pleasure they take in sexual activity, and the more they experience guilt, shame, and sexual inhibitions.
<u>Explanation:
</u>
- The rigid beliefs that some married couples bear about virtues and sins cease them from engaging in activities that are inculcated on their minds as not virtuous.
- In most cases, the shyness that such couples bear becomes the reason for the distance between them.
- These traits that exist between married couples eventually lead them towards guilt and uneasiness.
Answer: A. no later than 30 minutes after sunset and until at least 30 minutes before sunrise.
Explanation: Driving is guided by rules and driving rules may differ from one state to another. However, in California, in a bid to ensure that drivers and motorist have a clear vision or sight of their path, drivers behind the wheel must turn on their headlights no later than thirty minutes after sunset and until at least 30 minutes before sunrise.
