The networks grow around our neurons. -What makes them grow? Learning! “Learning is brain change,” says Professor James Zull from Case Western University in Cleveland, Ohio, US A. “Without learning, nothing changes in the brain. For every new word you learn in your English lesson, every...
Neurons come in many sizes. For example, a single sensory neuron from your fingertip has an axon that extends the length of your arm, while neurons within the brain may extend only a few millimeters. They also have different shapes depending on their functions.Motor neuronsthat controlmusclecont...
Serotonin is one of the chemicals in the brain that transmits signals between the billions of neurons that constantly communicate with each other, allowing the body to think and act. Serotonin (produced in each individual neuron from an amino acid called tryptophan) is typically active in the ...
What are the signs and causes of a dysregulated nervous system? Sometimes, your body's way of responding to certain situations can fall out of sync. This off-balance state in your nervous system is called a dysregulated nervous system. There are many common signs that show your nervous system...

If the brain is hardwired to maintain a certain body weight, how do people become obese? There are conflicting hypotheses among obesity researchers, but one theory involves so-called AgRP neurons, a cluster of brain cells in the hypothalamus. These cells play a powerful role in appetite: Inhib...
synapse formation between neurons in the brain are involved in the alimentary synapse formation. "If these genes are affected in autism," he says, "it could explain why so many kids with autism have GI motor abnormalities" in addition to elevated levels of gut-produced serotonin in their ...
