What's with the brain controlling head,arm,leg in an upside down way?

In summary, the conversation discusses the role of the cerebralcortex in controlling different parts of the body and how this is represented in the brain. The motor cortex is responsible for controlling movements, but it does not directly connect to the body parts. Instead, it controls the pathway that leads to the body part's control. The brain's representation of the body's control is distorted, and there is no correct vertical orientation for processing information. This distortion is due to complex evolutionary reasons.

Hello everyone,

Ok in the cerebralcortex I saw a pic where there is upside down HAL, the brain controls head,arm, leg upside down. Now I don't know much about this area. I know there is only motor cortex, so are these areas referring to axons that are coming out of motor cortex and supplying these correspondinga areas. Thanks :smile:

It means that if you move your leg, for example, that a particular area of the motor cortex will be active. Of those neurons that are active, a certain number of them will connect to other neurons (or many other neurons) that eventually exit the brain as a nerve bundle of axons that control the leg.

It's not that the axons directly leave the motor cortex and connect to the leg directly, just that they control the pathway that leads to the leg's control.

As for being upside down, the brain is just a processor of information, there's really no way to say which is the correct vertical orientation to process information in. The representations of the bodies control in the brain are distorted, "upside down", switched left/right etc. This is because of complex evolutionary reasons (yet another reason creationism is ridiculous).
 

1. Why does the brain control the head, arm, and leg movements in an upside down way?

The brain controls the body's movements through a complex network of neurons and neural pathways. The brain's control over the body is based on evolutionary development and the body's anatomy. The brain is located at the top of the body, and its control over the head, arms, and legs reflects this positioning.

2. How does the brain control the body's movements?

The brain sends signals through the spinal cord and nerves to the muscles, allowing for voluntary and involuntary movements. The brain also receives feedback from the body's sensory receptors, allowing it to adjust and refine movements as needed.

3. Can the brain control the body's movements in a different way?

While the brain's control over the head, arms, and legs may seem upside down, it is actually the most efficient and effective way for the body to move. The brain has evolved to control the body in this manner, and any attempts to change it could result in impairments or difficulties in movement.

4. Are there any benefits to the brain controlling the body in an upside down way?

Yes, the brain's control over the body in an upside down way allows for better coordination and balance. This also allows for more precise movements, such as fine motor skills, which are important for tasks such as writing and playing musical instruments.

5. Does the brain control all body movements in an upside down way?

While the brain controls the head, arms, and legs in an upside down way, it also controls other body movements in a similar manner. For example, the brain controls the left side of the body with the right side of the brain, and vice versa. This is known as contralateral control and allows for more efficient and coordinated movements.
