The Curious Case of Phineas Gage's Brain. Cabinet-card portrait of brain-injury survivor Phineas Gage (1823–1860), shown holding the tamping iron which injured him.

For the UK musical band, see Phinius Gage. Phineas P. Gage (1823 – May 21, 1860) was an American railroad construction foreman remembered for his improbable[B1]:19 survival of an accident in which a large iron rod was driven completely through his head, destroying much of his brain's left frontal lobe, and for that injury's reported effects on his personality and behavior over the remaining twelve years of his life—effects sufficiently profound (for a time at least) that friends saw him as "no longer Gage. " [H]:14. Mike the Headless Chicken. Beheading 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. 800L Owww. 1390L Fragile Brains. A Venus Flytrap Works Just Like Your Brain. 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.
Photo In the late 1800s, a group of German researchers identified other regions of the cortex, each having distinct types of cells packed together in unique ways. 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. We now have the term “memory neurons” to refer to the nerve cells of the hippocampus, which seem to play a crucial role in storing and retrieving memories. Since the original proof that at least some memory is localized to specific physical neurons just a few short years ago, understanding of the physical basis of memory has advanced at a lightning pace. Even in the past year, scientists have made incredible strides. Here is a rat set up so that certain neurons will fire in response to a UV light. Brain implants are still a bit unwieldy… 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. This is what happens to the brain during a concussion. The Science of Fear. What are you afraid of?

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. Neural eng ethical. 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. Students will build models, field webquests, conduct research, and take part in hands-on investigations. All lesson plans are aligned to the Washington State K-12 Science Standards, Next Generation Science Standards, and Common Core State Standards.
