What part of the brain coordinates the activities of the two sides of the body?

The major motor pathway that controls (the majority of) our muscles is called the Corticospinal Tract. This set of neurons starts (has its cell bodies/dendrites) in the Primary Motor Cortex (M1), and projects (sends axons) down through the brain and into the spinal cord, allowing us to move.
The neurons that control the left side of our body do indeed begin on the right side of our brain in the M1 area. The axons of these neurons stay on that side of the brain through the internal capsule, through the cerebral penduncle (in the midbrain), and to the medullary pyramid (in the medulla).
At this point, the axons decussate - cross over from one side to the other - and continue down the corticospinal tract in the spinal cord, where they eventually synapse to other neurons that leave the spinal cord and affect our muscles. It is this decussation in the medullary pyramid that leads to one side of our brain controlling the other side of our body.
Since axon decussation has evolved in many distinct systems and organisms, it seems reasonable to presume that decussation confers a significant functional advantage - yet if this is so, the exact nature of this advantage is not clearly understood.
Current research seems to indicate that in order to reduce connection errors in a complex computing network such as the human brain and CNS, with its 3-dimensional somatotropy, axonal decussation across the midline and corticospinal tract would be necessary.

What is the communication network called that controls and coordinates most body activities?
The nervous system is the communication and control system for the body.
What part of the brain controls conscious activities of the body?
The part of the brain that controls conscious activities of the body is the pituitary gland. It is usually located at the base of the skull.
Which side of the brain do you use when you draw?
Your right brain is on the right side of your head. However, the motor cortex (or motor strip) controls movements on the left side of your body. The right brain is more involved in spatial activities, overall, whereas the left brain has more involvement with speech and language (Broca's and Wernicke's areas).
What is the most important part of your body?
The most important part of the body is the central nervous system (brain and spinal cord) because it controls and coordinates all other metabolic processes throughout the body.
What regulates your body activities?
Your heart, brain, and lungs because without them you would not be able to walk, run, or even live! So you need your heart, brain & lungs to regulate your body activities.hope this helps with homework!(:
What region of the brain coordinates the nervous and endocrine systems and controls many body activities related to homeostasis?
Hypothalamus
What is the communication network called that controls and coordinates most body activities?
The nervous system is the communication and control system for the body.
What balances and coordinates the body's movement?
your brain
What body part balances and coordinates all the body movements?
the muscles
Area of the brain that coordinates body movements?
cerebellum
What balances and coordinates all of the body's movement?
your brain
What parts of the brain that coordinates body movements?
cerebellum
What do you do without a brain?
Nothing. Brain is the body part which coordinates all the bodily functions.
What coordinates the effects on the body?
the brain along with the nervous system
What is the cerebrullum?
The cerebrullum is section of the brain that coordinates body movements.
What coordinates the activity of all human body systems?
brain
What is a brain hemisphere?
they are sides of the brain that control eachother's side of the body.
