What are synapses?
Synapses are the tiny gaps between neurons, the brain's specialized cells. They act as bridges, allowing electrical and chemical signals to pass from one neuron to another. This transmission of signals is essential for everything we do, from thinking and feeling to moving and learning.
How do synapses work?
When an electrical signal reaches the end of a neuron, it triggers the release of chemical messengers called neurotransmitters. These neurotransmitters cross the synapse and bind to receptors on the next neuron, generating a new electrical signal. This process repeats, forming complex neural circuits that control our thoughts and actions.
Why are synapses important?
Synapses are crucial for brain function and development. They strengthen with repeated use, forming the basis of learning and memory. Conversely, weakening or loss of synapses can contribute to neurological disorders.
Can synapses change?
Yes! Synapses are highly adaptable and can be strengthened or weakened depending on their activity. This process, called synaptic plasticity, allows us to learn new things and adapt to our environment.
