Diagram of Brain In this diagram of the brain the different sections are shown. The Cerebrum are the two large hemispheres of the brain. Each hemisphere is further divided into lobes. Above is the break up of where each lobe is located and the structures under the cerebrum that make up the rest of the brain. Diagramed above are some of the major cortexes and their locations. This is what's known as a sagittal view of the brain. We recommend investing in this guide to human physiology and anatomy. We recommend investing in this guide to human physiology and anatomy.
Brain Functions and Diagram Brain Functions and Diagram Recognizing where damage is located and understanding the effects Neuro Point of View by: Dr. William Winslade Among the most devastating effects of head injury is the secondary damage that can follow hours and days later. Scientists still don't understand how the brain heals itself, so long-term recovery from any traumatic brain injury is uncertain, and its course is difficult to predict. Recovery from traumatic brain injury may be quick or slow; it may be complete, partial, or absent. People who do recover from traumatic brain injury must be highly motivated and persistent. The most comforting stories about recovery from traumatic brain injury have the timeless power of great myths. Dr.
Fear Can Be Erased from the Brain Newly formed emotional memories can be erased from the human brain. This is shown by researchers from Uppsala University in a new study now being published by the academic journal Science. The findings may represent a breakthrough in research on memory and fear. Thomas Ågren, a doctoral candidate at the Department of Psychology under the supervision of Professors Mats Fredrikson and Tomas Furmark, has shown, that it is possible to erase newly formed emotional memories from the human brain. When a person learns something, a lasting long-term memory is created with the aid of a process of consolidation, which is based on the formation of proteins. In the study the researchers showed subjects a neutral picture and simultaneously administered an electric shock.

Short-term memory is based on synchronized brain oscillations Scientists have now discovered how different brain regions cooperate during short-term memory. Holding information within one's memory for a short while is a seemingly simple and everyday task. We use our short-term memory when remembering a new telephone number if there is nothing to write at hand, or to find the beautiful dress inside the store that we were just admiring in the shopping window. Yet, despite the apparent simplicity of these actions, short-term memory is a complex cognitive act that entails the participation of multiple brain regions. However, whether and how different brain regions cooperate during memory has remained elusive. A group of researchers from the Max Planck Institute for Biological Cybernetics in Tübingen, Germany has now come closer to answering this question. It has long been known that brain regions in the frontal part of the brain are involved in short-term memory, while processing of visual information occurs primarily at the back of the brain.
Schizophrenia diagnosis associated with progressive brain changes among adolescents Adolescents diagnosed with schizophrenia and other psychoses appear to show greater decreases in gray matter volume and increases in cerebrospinal fluid in the frontal lobe compared to healthy adolescents without a diagnosis of psychosis, according to a report in the January issue of Archives of General Psychiatry, one of the JAMA/Archives journals. “Progressive loss of brain gray matter (GM) has been reported in childhood-onset schizophrenia; however, it is uncertain whether these changes are shared by pediatric patients with different psychoses,” the authors write as background information in the study. Celso Arango, M.D., Ph.D., of the Hospital General Universitario Gregorio Marañón, Madrid, Spain, and colleagues, examined the progression of brain changes in first-episode early-onset psychosis and the relationship to diagnosis and prognosis at two-year follow-up among patients at six child and adolescent psychiatric units in Spain.
Brain analysis can help predict psychosis: study Hippocampus plays bigger memory role than previously thought Human memory has historically defied precise scientific description, its biological functions broadly but imperfectly defined in psychological terms. In a pair of papers published in the November 2 issue of The Journal of Neuroscience, researchers at the University of California, San Diego report a new methodology that more deeply parses how and where certain types of memories are processed in the brain, and challenges earlier assumptions about the role of the hippocampus. Specifically, Larry R. Recollection and familiarity memory are two components of recognition memory – the ability to identify an item as having been previously encountered. Prevailing research posits that recollection and familiarity memories involve different regions in the brain's medial temporal lobe: the hippocampus for recollection, the adjacent perirhinal cortex for familiarity. Recollection-based memories are typically associated with higher confidence and accuracy than familiarity-based decisions.
October is Lewy Body Dementia Awareness Month To be honest, I didn’t really learn about Lewy Body Dementia (LBD) until I read a press clipping from New York University Langone Medical Center. I typically associate October with falling leaves, the sudden appearance of pumpkins everywhere, and my birthday, so I was surprised to learn that this month is also dedicated to raising awareness for a disease that affects about 1.3 million people in America. Despite its prevalence, LBD is under-treated and under-recognized. Lewy Body Dementia is aptly named for its etiology—abnormal protein deposits called Lewy bodies build up in the brain cells that control various aspects of memory and motor control; the interruptions of these systems is why LBD is widely misdiagnosed. Raising awareness is important because it leads to proper diagnoses, more research, and better treatments. --Caitlin Schneider Source: NYU Langone Medical Center fact sheet and definition page
High Brainwaves Critical for Learning and Memory Scientists at MIT were studying the brains of rats as they learned how to navigate through a maze. They found that during the first few trials there was a lot of activity in high-frequency brainwaves, including beta waves (between 13-30 cycles per second) and gamma waves (between 30-100 cycles per second). Once the rats learned the maze, activity in these brainwaves decreased. This suggests that high frequency brainwaves are associated with learning and memory. And once the task was learned, future trials showed the rats were in a much more relaxed and low frequency brain state. This is because the brain no longer needed those high frequency brainwaves to help focus on the task. Remember when you first learned how to tie your shoes and you really had to focus? This fits well with other research on brain waves. Interestingly, for the past month and a half I’ve been using an audio program named Laser Focus, which uses a technology called brainwave entrainment.
New imaging after strokes opens doctors', victims' eyes at Edison hospital Noah K. Murray/The Star-LedgerDr. Jawad Kirmani looks into the eye of Rob Schneider during a neurological check up at JFK Medical Center in Edison. EDISON — Nausea and dizziness descended on Jasal Amin one Monday last June. Three days later, the 45-year-old East Brunswick man lay in a hospital, where he slowly slipped into a coma. Though Amin was unresponsive, advanced imaging showed his brain was still very much alive. So doctors at JFK Medical Center in Edison decided to push the limits of treatment. The recovery was dramatic. The onset of a stroke begins a race against the clock to limit damage. But recent advances in imaging technology are giving some severe stroke victims a chance outside the traditional time frames. In the past two years, doctors at JFK’s comprehensive stroke center have operated on 66 patients like Amin who have suffered massive strokes but whose brains refuse to die. Noah K. "On the CAT scan, we saw a live brain," Kirmani said, referring to Amin. Noah K. Noah K.

Watch this free video lecture and delve into the fascinating science behind how your brain works to create and use memories. Memory and the Brain is delivered by neuroscientist and award-winning Professor Jeanette Norden of Vanderbilt University.
Neuroscientists identify how the brain remembers what happens and when New York University neuroscientists have identified the parts of the brain we use to remember the timing of events within an episode. The study, which appears in the latest issue of the journal Science, enhances our understanding of how memories are processed and provides a potential roadmap for addressing memory-related afflictions. Previous research has shown the brain's medial temporal lobe (MTL) has a significant role in declarative memory—that is, memory of facts and events or episodes. Past studies have shown that damage to the MTL causes impairment in memory for the timing of events within an episode. The NYU researchers—Yuji Naya, an associate research scientist, and Professor Wendy Suzuki, both of NYU's Center for Neural Science—focused their study on the MTL. Their results showed that two main areas of the MTL are involved in integrating "what" and "when": the hippocampus and the perirhinal cortex.

Your lying brain: The quest for a reliable lie detector test | Science Anyone familiar with daytime TV relationship gurus such as Jerry Springer and Jeremy Kyle will have seen polygraphs in action. The accused husband/girlfriend/mother is hooked up to a lie detector as they face a barrage of questions. The machine monitors something known as skin conductance, basically the moisture level of the skin, which usually changes when someone is telling fibs. But polygraph tests can be manipulated by the subject (see various guides on how to cheat a polygraph) and their validity and reliability have been challenged for decades. Surely, with the huge advances we've seen in neuroscience and brain imaging in recent years, there must be a more reliable way to detect deception? Research looking at changes and patterns in brain activity has identified areas of the brain, known as the prefrontal cortices, that seem to play a part in preventing someone telling the truth, while also helping them to generate a false response. Scientists are unconvinced of claims like this.
