How Neurons Communicate

A synapse is a chemical or electrical connection that allows electrical signals to be transferred from neurons to other cells.

Communication between neurons is strengthened or weakened by individual activities such as exercise, stress, drug use

The behavior of neurons in the brain is complicated. A single pyramidal neuron is a sophisticated computer. Understanding the principle of how these neurons communicate within the brain clearly emphasizes the inappropriateness of ANN point neurons that capture the complexity of brain activity. It's too simple and very static. Biological neurons are very plastic - it constantly grows new dendrites, and when you forget things old couplings will degenerate and disappear, and new patterns will be formed with new bonds.

How do neurons communicate? When a nerve impulse reaches a neuron, the neuron is activated and releases a chemical called a neurotransmitter at the site where the synapse or two neurons are connected. Neurotransmitters pass through the synapse where they bind to receptor molecules located on adjacent neurons. The binding of this neurotransmitter activates the second nerve cell, such as sending the neurotransmitter to the next nerve cell. As the nerve impulse propagates throughout the brain, this process continues from the neuron to the neuron.

Neurons communicate with other neurons at specific locations called synapses or synaptic gaps. To transmit information, neurons release chemical messengers or neurotransmitters into the synaptic cleft. From there, neurotransmitters pass through the synapse and adhere to important sites called receptors of the next neuron. When neurotransmitters attach to these receptors, they cause changes in the receiving neurons and transmit information. Neurons communicate with one another through interconnected cellular networks scientists are still trying to fully understand. Scientists know that this complex communication system in the brain can be destroyed by chemicals in the drug. Do you know that there are over 400 chemicals on hemp leaves? In addition to nicotine there are over 4,000 chemicals in cigarettes!

Communication neurons often contact adjacent brain cells. When a neuron receives a signal from another neuron it generates a charge that propagates along its length and releases a neurotransmitter through a small gap called a synapse. Like a locking key, each neurotransmitter molecule binds to a specific receptor site on the neuronal dendrites in the vicinity. This process triggers a chemical or electrical signal that stimulates or inhibits the activity of neurons receiving the signal. Communication often occurs in brain cell networks. In fact, scientists estimate that neurons have 7,000 synaptic connections with other neurons in the brain's communication network.
