What do you need for a limb to move?
For a limb to move, you need muscles, nerves, and a signal from the brain. The brain sends signals through nerves to the muscles, which contract and allow the limb to move.
How many soldiers in American history returned with loss of limb?
Hold on.... Let me count......
How many brain cells does a woman have?
Brain cells are to numerous to count. There are billions of them. No one has ever tried to count them.
How does mirror therapy work in managing phantom pain?
On a basic level: Mirror therapy takes advantage of neuroplasticity. Phantom limb pain arises when the brain believes that the limb is stuck in an uncomfortable position but cannot be moved. Using the mirror box the brain can be tricked to believe that the limb is moving and thus believes that the problem is solved. Hope this helped somewhat.
What does evidence suggest about the neural networks that mediate the sensations of phantom limb pain?
Evidence suggests that phantom limb pain is mediated by changes in the neural networks of the brain, particularly involving maladaptive plasticity in regions like the primary and secondary somatosensory cortices. These changes can lead to abnormal sensations and pain in the absence of the limb. Additionally, alterations in the connectivity between different brain regions may play a role in the development and maintenance of phantom limb pain.
How can the Venus Flytrap count to ten?
It's a PLANT. It doesn't have a brain. It can't count. Nor think.
How do you say cut you from limb to limb in old English?

The brain of a goldfish?
Fairly intelligent. Well they can count to five!
How is a phantom limb and a sensory homunculus linked?
V. Ramachandran desribes a bit of this in his book "The Emerging Mind". The Penfield-Homunculus is not an exact replica of the body, because the face is located directly besides the hand. Therefore, when a person is missing one arm, the neurons can cross-link, that is when they don't receive any input they form connections with the nearest area - in this case the face. This is why people with phantom limbs sometimes feel their missing hand when their face is touched, another example is that when the face is stimulated with ice cubes, they feel as if the phantom limb got cold.
Why may a person need to have a limb amputated?
The pain or feeling is known as "Phantom Pain" and is commonly reported by amputees. It's believed to be related to our body's electrical field - under Kirlian photography, plants that have had their leaves severed still show the outline of its bioelectric field after the piece has been cut and removed. Though the mechanism isn't fully understood, the pain signals to the brain from a severed limb or other injury are known to continue well after the area has apparently healed. Some theories believe that the nerve being severed causes an overload in the electric signals to the brain, which continue to be sent by the nerve path to the brain after the limb is gone. Since the nerve pain originated in the limb, the brain signals make it seem like the pain is actually coming from the limb when in fact it's not.
How many parts does the bain have?
There are five lobes of the brain. If you count the brain stem as a part, then it would be six. If not, it would be five.
How is surgery used to treat phantom limb syndrome?
Surgical treatments for phantom limb pain are limited in benefit. Lesions of various pain centers in the spinal cord and brain can be performed, and may provide short-term relief on most occasions.
