Studies of the brain: Boy recovers normal life after losing big part of his brain

Surgery to remove a brain tumor took much of the patient's vision. But the remaining part of his brain has adjusted.

A boy who lost a large part of his brain to a brain tumor has recovered to a remarkable degree, the rest of his brain having rewired itself to compensate, researchers reported Tuesday.
Surgeons removed a third of one entire lobe of Tanner Collins’ brain to stop seizures caused by a benign brain tumor when he was 6. With it went the entire visual processing center for his left eye. But the remaining part of his brain has adjusted, the team at Carnegie Mellon University in Pittsburgh reported in the journal Cell Reports.

Use of the Term "Vegetative State" is Dehumanization in Its Most Literal Form

Image
By   Sherry Phipps  swp@protonmail.com The term “vegetative state” has been used in the medical field for decades to describe patients who have lost cognitive function due to severe brain injury. However, the use of this term is increasingly being criticized for its dehumanizing connotations. This article explores why the term is problematic and suggests alternatives that respect the dignity of patients. The Problem with the Term The term “vegetative state” is derived from the word “vegetable,” implying a lack of consciousness or awareness. This comparison is not only scientifically inaccurate but also deeply disrespectful. It reduces a human being, with their unique history, personality, and potential, to the status of a plant. Moreover, the term can lead to harmful misconceptions. It may cause people to believe that these patients are incapable of experiencing pain or emotions, which is not always the case. Some research suggests that certain patients in a so-called vegetative state

Breakthrough Brain Implant Technology for TBI

Image
  After suffering a traumatic brain injury in 2001,  Gina Arata would often trip over things, get mad easily, and forget basic information. Today, however, a tiny implant is enabling Arata to live more like her pre-accident self. The device delivers targeted electrical stimulation to a part of the brain’s thalamus, with the goal of  “overdriving” it to restore brain function  — similar to how a pacemaker restores heart function, the researchers said.  Read the full article here:  https://www.freethink.com/health/tbi-brain-stimulation?utm_campaign=freethinkweekly&utm_source=rejoiner&utm_medium=email&utm_content=12%2F12%2F23+F%2A+Weekly&rjnrid=3NGOnGm
