Why dread a bump on the head? The neuroscience of traumatic brain injury This lesson serves as the introduction to the “Why dread a bump on the head?” unit. Students are introduced to traumatic brain injury (TBI) through pictures and discussions that help students break down prior assumptions and begin to think about TBI from a scientific perspective. Students learn about and discuss the three classifications of TBI, mild, moderate, and severe. These categories are presented through the reading and discussion of news articles. Students then examine a hypothetical situation where they are the doctors on a brain injury case.

Snakes? Turbulence? Spiders? The NSF Engineering Research Center for Sensorimotor Neural Engineering (CSNE) By Dr. Lise Johnson (CNSE Education Manager) What exactly is Sensorimotor Neural Engineering? That is a very good question, and one that I get asked frequently. Inevitably when you meet someone you get to talking about what you do for a living, and if you work at the Center for Sensorimotor Neural Engineering, it’s only natural for people to wonder what on Earth that is. Some people are polite about this, while others are more direct.

The NSF Engineering Research Center for Sensorimotor Neural Engineering (CSNE) Traumatic Brain Injury: A Neural Network Journey (DRAFT) Grades: Six to 12 This seven-lesson unit, aimed at middle school and high school students, provides background in neuroanatomy, neuroscience, and neural engineering with a special focus on traumatic brain injury. The plans were created by Michael Shaw, Cleveland High School (Seattle, Wash.), and Shannon Jephson-Hernandez, Mill Creek Middle School (Kent, Wash.). The unit culminates in a script writing exercise, with students composing a special report on traumatic brain injury. On The Move, Hallucinations, Musicophilia, Awakenings, The Man Who Mistook His Wife for a Hat Here Dr. Sacks recounts the case histories of patients lost in the bizarre, apparently inescapable world of neurological disorders: people afflicted with fantastic perceptual and intellectual aberrations; patients who have lost their memories and with them the greater part of their pasts; who are no longer able to recognize people and common objects; who are stricken with violent tics and grimaces or who shout involuntary obscenities; whose limbs have become alien; who have been dismissed as retarded yet are gifted with uncanny artistic or mathematical talents. If inconceivably strange, these brilliant tales remain, in Dr. Sacks’s splendid and sympathetic telling, deeply human. They are studies of life struggling against incredible adversity, and they enable us to enter the world of the neurologically impaired, to imagine with our hearts what it must be to live and feel as they do.

MIT discovers the location of memories: Individual neurons Update 12/2/15: We’ve now followed up on this story: The more we learn about memory, the weirder it gets. The original continues below. MIT researchers have shown, for the first time ever, that memories are stored in specific brain cells. By triggering a small cluster of neurons, the researchers were able to force the subject to recall a specific memory. By removing these neurons, the subject would lose that memory. As you can imagine, the trick here is activating individual neurons, which are incredibly small and not really the kind of thing you can attach electrodes to.

The more we learn about memory, the weirder it gets For much of the history of brain science, the word “engram” has been a bit of a catch-all term, referring to the hypothetical physical incarnation of memory. If this turned out to be a storm of electrical activity, then that’s what the engram would be; if it turned out that networks of physical neurons were the home of specific memories, then an engram was that, instead. Lately, though, the word has gotten a lot more specific.

Updated Brain Map Identifies Nearly 100 New Regions The first hints of the brain’s hidden geography emerged more than 150 years ago. In the 1860s, the physician Pierre Paul Broca was intrigued by two of his patients who were unable to speak. After they died, Broca examined their brains. On the outer layer, called the cortex, he found that both had suffered damage to the same patch of tissue. That region came to be known as Broca’s area. In recent decades, scientists have found that it becomes active when people speak and when they try to understand the speech of other people.

Mike the Headless Chicken Beheading[edit] On September 10, 1945, farmer Lloyd Olsen of Fruita, Colorado, United States, was planning to eat supper with his mother-in-law and was sent out to the yard by his wife to bring back a chicken. Olsen chose a five-and-a-half-month-old cockerel named Mike. The axe removed the bulk of the head, but missed the jugular vein, leaving one ear and most of the brain stem intact.[3][4] Due to Olsen's failed attempt to behead Mike, Mike was still able to balance on a perch and walk clumsily.
