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.
I believe the answer is :D <span>Recognizing an object is distinct from its surroundings.
In the concept of perception ,discrimination refers to the visual ability that make us able to separate the things that we want to focus on and the things that we do not. This allow us to utilize our brain capacity to solve the most important/crucial situation first</span>

Explanation:
If we denote the recessive allele of the gene as p and the dominant allele as P, the offspring will be of phenotypic ratio 3:1 those with chlorophyll to those without chlorophyll respectively. Genotypically, 25% would be homozygous for dominant allele, 50% heterozygous and 25% homozygous recessive.
Answer: Under the Great Law, democratic principles were built into the decision making process: equality among all chiefs, in the Grand Council with the same level of authority. ... men were nominated as chiefs (male authority) by women (female authority) both men and women belonged to the mother's clan (giving women authority)
All of the tribe thought the sachem was very wise and did the best thing for the tribe. He also had a council to help him make decisions, called sagamores. The tribe would present the sachem with gifts. The sachem was also in charge of the land the tribe lived on and decided about selling any of the land. Explanation:
Answer:
Every symptom is not a fever symptom in infants.
Explanation:
Fever occurs when the internal "thermostat" of the body increases the temperature of the body above its normal range.
A child's normal temperature varies with his or her age, activity, and even time of day.
Infants usually have greater levels of temperatures than children of more than 1-2 years. They may have higher temperature during late afternoon and early evening. Temperatures might be low between midnight and early hours of the morning. Checking temperature with palm on the forehead should not be the way to decide if the child has fever. Always use a thermometer to check body's temperature and conclude whether it is fever or not.
