What role do neurotransmitters play in the brain?

Neurotransmitters play a crucial role in the brain by allowing communication between nerve cells, or neurons. These chemical messengers transmit signals across the synapse - the gap between two neurons. They are responsible for modulating various brain functions such as mood, memory, sleep, and appetite. Different neurotransmitters have different effects on the brain and can either excite or inhibit the activity of certain neurons. Imbalances in neurotransmitter levels have been associated with various neurological and psychiatric disorders, highlighting the importance of these molecules in maintaining a healthy brain function. Medical interventions that target neurotransmitter systems, such as medication for depression that influences serotonin levels, have been developed to restore balance and alleviate symptoms of these disorders.
