What is Nerve Cells In The Brain?

Nerve cells, or neurons, in the brain are integral for mental functioning. They are responsible for communication between different parts of the brain and the rest of our bodies. Neurons work by sending electrical messages from one area to another and are made up of three major parts: a dendrite, a cell body, and an axon. The dendrites receive information from other neurons while the cell body processes that information to decide whether or not to send a message down its axon to another neuron.Neurons in the brain can be divided into two main categories: excitatory neurons and inhibitory neurons. Excitatory neurons send signals that cause other neurons to become more active, while inhibitory neurons send signals that cause other neurons to become less active. Most nerve cells in the brain use both kinds of signaling; this is how complex thoughts and behaviors can occur – through a combination of excitation and inhibition in different parts of the brain. The number of nerve cells in our brains is fixed at birth; we cannot produce new ones as we age. However, neuroscience research has shown that neuroplasticity allows us to create new pathways between existing nerve cells as we learn new skills or form new memories. This is why it’s important to keep your mind active by learning new things – you can create more connections between existing nerve cells so they can process information more efficiently. In summary, nerve cells play an essential role in our mental functioning by sending electrical messages around the brain which allow us to think and behave complexly.
