How do a box jellyfish move?
Box jelly fish move by neurons. Neurons are there brains.
Do bees have brains?
Bees have one of the largest brains among insects. Their brains have nearly a million neurons, compared with about a billion in a human brain.
Have bees got brains?
Yes, bees do have a brain. It has around 950,000 neurons compared to the more than a billion neurons in a human brain.
Are pulsars a kind of neuron star?
No, neurons are cells which are found in brains - nothing to do with stars.
What is the role of the neuron?
Neurons are like they brains messengers. The brain figures out what needs to be done and the neurons tell they body to do it.
Are intelligent humans have bigger brains?
size of the brain has nothing to do with intelligence. only the capacity of the neurons
How can be cloning done?
Creating neurons and linking them with each other creates clone of a brain. Simple brains with only 4-5 neurons linked can be created first before creating complex human brain.

Do the vertebrates have brains?
That would depend on the animal. Practially all vertebrates have brains, with mammals' and perhaps birds' being the most complex of all. For invertebrates, it depends on the species. Arthropods and cephalopods tend to have brains. Sponges have no neurons whatsoever.
How do rat brains work?
All animal brains, including human brains, work in essentially the same way. There are a whole lot of nerve cells, also called neurons, and any given neuron can either fire or not fire. If it fires, it sends a signal down all of its dendrites and axons. Neurons are connected to lots of other neurons in various complicated ways. They also have connections to other parts of the body. Neurons receive sensory information, and send out messages that control muscles. The signals that neurons receive determine whether they fire or not. Impulses can also pass or fail to pass from one neuron to another, across a small gap called a synapse, depending upon the amount of neurotransmitters in the synapse. Those are the variables. Together, they create a complex data processing system.
Do you get wrinkles in the brain every time you learn something?
We don't start out with wrinkly brains, however; a fetus early in its development has a very smooth little brain. As the fetus grows, its neurons also grow and migrate to different areas of the brain, creating the sulci and gyri. By the time it reaches 40 weeks, its brain is as wrinkled as yours is (albeit smaller, of course). So we don't develop new wrinkles as we learn. The wrinkles we're born with are the wrinkles we have for life, assuming that our brains remain healthy. Our brains do change when we learn -- it's just not in the form of additional sulci and gyri. This phenomenon is known as brain plasticity. By studying changes in the brains of animals like rats as they learn tasks, researchers have discovered that synapses (the connections between neurons) and the blood cells that support neurons grow and increase in number. Some believe that we get new neurons when we make new memories, but this hasn't yet been proven in mammalian brains like ours.
What branch of science involves brains?
Neuroscience is the study of the nervous system -- including the brain, the spinal cord, and networks of sensory nerve cells, or neurons, throughout the body.
