Brain Damaged 'Patient R' Challenges Theories of Self Awareness
According to some theories on how self-awareness arises in the brain, Patient R, a man who suffered a severe brain injury about 30 years ago, should not possess this aspect of consciousness.
In 1980, a bout of encephalitis caused by the common herpes simplex virus damaged his brain, leaving Patient R, now 57, with amnesia and unable to live on his own.
Even so, Patient R functions quite normally, said Justin Feinstein, a clinical neuropsychologist at the University of Iowa who has worked with him. "To a layperson, to meet him for the first time, you would have no idea anything is wrong with him," Feinstein said.
Feinstein and colleagues set out to test Patient R's level of self-awareness using a battery of tools that included a mirror, photos, tickling, a lemon, an onion, a personality assessment and an interview that asked profound questions like "What do you think happens after you die?" [The Science of Death: 10 Morbid Tales]
Their conclusion ? that Patient R's self-awareness is largely intact in spite of his brain injury ? indicates certain regions of the brain thought crucial for self-awareness are not.
Brain anatomy
Self-awareness is a complex concept, and neuroscientists are debating from where it arises in the brain. Some have argued that certain regions in the brain play critical roles in generating self-awareness.
The regions neuroscientists have advocated include the insular cortex, thought to play a fundamental role in all aspects of self-awareness; the anterior cingulate cortex, implicated in body and emotional awareness, as well as the ability to recognize one's own face and process one's conscious experience; and the medial prefrontal cortex, linked with processing information about oneself.
Patient R's illness destroyed nearly all of these regions of his brain. Using brain-imaging techniques, Feinstein and colleagues determined that the small patches of tissue remaining appeared defective and disconnected from the rest of the brain. [Inside the Brain: A Journey Through Time]
The tests
The team breaks self-awareness down into three components: an awareness of one's body and a sense of one's ability to act; autobiographical memories and a sense of one's own traits; and an ability to reflect on one's own actions, mental state and their consequences.
The first test they gave Patient R is the mirror test. The researchers sneaked a bit of black eye shadow onto R?s nose under the pretense of brushing something off his nose. When he was later shown his reflection in the mirror, the researchers watched to see if he responded to the mark on his nose.
He was also shown photos of himself throughout his life along with photos of family, familiar people and strangers and asked whether or not he could identify himself. In unaltered photos, he was 100 percent successful in identifying himself, but he had difficulty recognizing himself in photos altered to exclude everything except his own face.
"However, he never rated a picture of another person as himself," note the researchers.
R suffers from amnesia that affects memories of some experiences that occurred before his illness, and prevents him from forming new memories since, so these results suggest he was able to maintain a concept of himself even beyond his own amnesia, Feinstein said.
In another test, R's response to being tickled by himself versus by a researcher, was recorded. Tickling can be used to test self-awareness because tickling yourself doesn't feel the same as being tickled by someone else. "R was never observed laughing or displaying jerking movements during any of the self-administered tickling trials," they write.
Researchers assessed his awareness of the amount of control he exerted over a box moving around a computer screen, and had him and family members assess his personality.
An exception
R's brain injury took away his sense of smell and taste, as well as much of his memory. R partially acknowledges his memory loss, even describing himself as a "normal person with a bad memory," However, he does not admit that he cannot smell or taste.
The researchers put this to the test by blindfolding him and then offering him an onion or lemon or odorless items and asking what he smelled. With the blindfold on, he could not smell the lemon or onion. With it off, he claimed to smell them, explaining, "I guess sight makes things easier."`
Knowing one's limitations is an aspect of self-awareness, Feinstein said.
Patient R & the origin of self-awareness
Finally, in an interview the researchers assessed his capacity for introspection, asking him questions about free will, the self, emotion and other abstract concepts.
"I think what the interview reveals is clearly somebody who is not impaired in most aspects of self-awareness," Feinstein said. ?"If you were asking someone who was a zombie, you wouldn't get any of these sorts of answers."
The results of the assessment are clear, he and colleagues contend: Neither the insula cortex, the anterior cingulate cortex nor the medial prefrontal cortex play crucial roles in self-awareness.
Patient R's self-awareness does, however, support the theory that sets of neurons in the brain stem may provide the foundation for consciousness and the sense of self. This part of R's brain is undamaged. The team also suggests other parts of the brain, the thalamus and the posteromedial cortex, play a role in self-awareness.?
"The brain more than likely doesn't have a single region that is devoted to self awareness, but rather, the complex phenomenon likely emerges from much more distributed interactions between multiple brain regions," Feinstein said. "I think it is important to emphasize that the study of self-awareness in the brain is really in its early stages."
The research was published today (Aug. 22) in the journal PLoS ONE.

The best college in Texas? Rice only two spots ahead of Texas A&M, well behind UT in new rankings
Rice University students may be happy, but that doesn't mean they go to the best college in Texas.
That's according to the Center for World-Class Universities at Shanghai Jiao Tong University, which released its 10th annual Academic Ranking of World Universities this week. Rice placed on the list at No. 91 globally and No. 50 in the United States.
?UT has only seen its status improve, with a slowly climbing trajectory from No. 47 to No. 35 in the past 10 years.?
The University of Texas took the top spot in Texas, coming in at No. 35 overall and No. 27 nationally. Other Texas schools on the top 100 included The University of Texas Southwestern Medical Center at Dallas (the list doesn't distinguish between undergraduate and doctorate institutions) at No. 48 and Texas A&M at No. 93.
The ARWU ranking focuses on research and status criteria, with factors including the number of alumni and staff who win Nobel Prizes and Fields Medals, how many researchers are selected as 'highly cited' by Thomson Scientific and the number of articles published in journals of nature and science and indexed in Science Citation Index.
Rice's ranking represents an improvement from its placement in recent years, moving up from 93 in 2011 and 99 in 2009-2010, but still marks a significant fall-off from its No. 61 ranking in 2003, the first year of the list.
Meanwhile UT has only seen its status improve, with a slowly climbing trajectory from No. 47 to No. 35 in the past 10 years.

Biden to be in Tampa as GOP convention opens
MINNEAPOLIS (AP) ? Vice President Joe Biden is planning to be in Tampa, Fla., next week as Republicans open their presidential nominating convention in the city.
An Obama campaign announcement on Tuesday said Biden will be attending events in Florida on Monday and Tuesday, including a stop in Tampa on the convention's opening day.
President Barack Obama won Florida four years ago, but Republicans are hoping the week-long convention will help them recapture the key battleground.
The campaign announcement didn't detail what other cities Biden will be appearing in.
Campaigning in Minneapolis, Biden talked about his upcoming trip to Tampa with reporters.
"Any of you going to Florida?" he asked the reporters. "I'm going to be the speaker at the convention."
This was after Biden visited a high school football practice, which he also did during a trip last week.

the daily | news and information for Case Western Reserve University
Posted: August 21st, 2012 | Author: thedaily | Filed under: news, research | No Comments ?
Nanoparticles tailored to latch onto blood platelets rapidly create healthy clots and nearly double the survival rate in the vital first hour after injury, new research shows.
?We knew an injection of these nanoparticles stopped bleeding faster, but now we know the bleeding is stopped in time to increase survival following trauma,? said Erin Lavik, a professor of biomedical engineering at Case Western Reserve University and leader of the effort.
The researchers are developing synthetic platelets that first responders and battlefield medics could carry with them to stabilize car crash or roadside bomb victims. An injection could slow or halt internal bleeding until the victim reaches a hospital and receives blood transfusions and surgery.
Lavik spoke about the latest breakthroughs in her research Monday at the American Chemical Society?s annual meeting in Philadelphia.
Lavik and her colleagues began focusing on synthetic platelets after learning the military has no equivalent of a tourniquet, pressure dressing or other easily transportable technology to stem bleeding from internal injuries.
But as they explored possible applications, they recognized that the approach is widely needed beyond military conflict. Traumatic injury is the leading cause of death for people age 4 to 44, often overwhelming the body?s natural blood-clotting process.
The platelet-like nanoparticles are made of biodegradable polymers used in devices already approved by the Food & Drug Administration for use in humans. They?re designed to hone in on injuries after injection. Natural platelets, activated by injury, emit chemicals that bind natural platelets and the additional synthetics into a larger clot faster than natural platelets alone.
Tested on a lethal liver injury model in lab rats, the one-hour survival rate of the models injected with the nanoparticles was 80 percent. For control groups treated with saline alone the survival rate fell to 47 percent, while control groups receiving scrambled nanoparticles totaled just 40 percent. Among the three, the models treated with the platelet-like nanoparticles exhibited the least blood loss.
The researchers also found that the hybrid clots were as firm as natural clots. In additional testing, they found no complications following administration of the nanoparticles.
Earlier tests showed these synthetic platelets can cut bleeding time by as much as half and that, a week later, the rats showed no ill effects from the materials
The researchers include graduate students Andrew J. Shoffstall, Lydia M. Everhart and Margaret M. Lashof-Sullivan; research assistants Kristyn T. Atkins and Rebecca E. Groynom; undergraduate student Matt E. Varley; and administrative assistant Blaine Martin-Dow, all of Case Western Reserve. They are teamed with Robert S. Butler, of the Department of Quantitative Health Services at the Cleveland Clinic, and Jeffrey S. Ustin, assistant professor, Case Western Reserve University School of Medicine and member of the Department of General Surgery at the Cleveland Clinic.
They are continuing to test the platelets with other models of injury, working toward the best design and dosage for human use.
