Scientists have found a tiny new region of the
brain that only humans have - and they believe it could be what makes our
species unique.
Researchers say the incredible find could help
find a treatment for Parkinson's and motor neurone disease. For thirty years
scientists - who have likened the discovery to finding a new star - suspected
this region existed but were unable to see it.
Professor George Paxinos from Neuroscience
Research Australia (NeuRA) found the hidden region. He was able to find the
region, called the Endorestiform Nucleus, thanks to better staining and
imaging techniques.
'The region is intriguing because it seems to be
absent in the rhesus monkey and other animals that we have studied. This region
could be what makes humans unique besides our larger brain size', he said.

The region is found near the brain-spinal cord
junction. This is an area that integrates sensory and motor information to
refine our posture, balance and fine motor movements.
'I can only guess as to its function, but given
the part of the brain where it has been found, it might be involved in fine
motor control,' said Professor Paxinos.
The discovery of the region may help researchers
explore cures for diseases including Parkinson's disease and motor neurone
disease.

Parkinson’s disease affects one in 500 people,
and around 127,000 people in the UK live with the condition. It causes
muscle stiffness, slowness of movement, tremors, sleep disturbance, chronic
fatigue, an impaired quality of life and can lead to severe disability. Motor
neurone disease is when specialist nerve cells in the brain and spinal cord
called motor neurones stop working properly.

Neuroscientists researching neurological or
psychiatric diseases already use Professor Paxinos' maps to guide their work. His brain atlases are heralded as the most
accurate for the identification of brain structures and are also used in
neurosurgery.
'Professor Paxinos' atlases showing detailed
morphology and connections of the human brain and spinal cord, provide a
critical framework for researchers to test hypotheses from synaptic function to
treatments for diseases of the brain,' said Professor Peter Schofield, CEO at
NeuRA. He is the author of the most cited publication in neuroscience and
another 52 books of highly detailed maps of the brain.
The maps chart the course for neurosurgery and
neuroscience research, enabling exploration, discovery and the development of
treatments for diseases and disorders of the brain.
His new findings are revealed in his latest book, Human Brainstem: Cytoarchitecture, Chemoarchitecture, Myeloarchitecture.

I had my TL a little more than a year ago when my third child was born via c-section. I was not told ANYTHING about the possible side effects of having this procedure. Since then I have experienced heavy bleeding lasting sometimes 3 weeks out of the month, weight gain, severe mood swings. Severe cramping, changes to my libido, severe depression accompanied by suicidal thoughts, headaches, migraines, many new symptoms & older issues are now exacerbated. The father of two of my children doesn't want me anymore. I've become too much of a pain in the ass I guess. We don't talk. We don't sleep in the same bed. I think he might really think I am crazy... & maybe I am. I feel crazy a lot of the time.
ReplyDeleteI'm unpredictable. I feel so angry about the whole thing & now what was once a mild fear of doctors has exploded into full on white coat syndrome that causes me to have a panic attack/hypertensive emergency (severe increase in blood pressure) whenever I have to deal with them. I'm not sure what to do... I fear the next time I have to see a doctor I'll have a stroke or a heart attack from the stress & anxiety of it... what do I do? I take my time and keep searching on internet looking for natural healing that how I came across Dr Itua herbal center website and I was so excited when Dr Itua told me to calm down that he will help me with his natural remedy I put my hope on him so I purchase his herbal medicines which was shipped to my address I used it as prescribed guess what? I'm totally healed my cramp pain is gone completely I also used his Anti Bacteria herbal medicines it's works for me very well I want anyone with health problem to contact Dr Itua herbal center for any kind diseases remedies such as Parkinson, Herpes, ALS, MS, Diabetes, Hepatitis, Hiv/Aids,Cancers, Men & Women Infertility, I got his email address drituaherbalcenter@gmail.com he has any kind of herbal remedies for women & men also for our babes. I really miss my Hunni...he's a fantastic father & a good man. He doesn't deserve this. I feel like an empty shell of who I used to be...
