Understanding Neuron Communication

Neurons communicate using electrical and chemical signals. Messages start as electrical signals, known as action potentials, traveling down a neuron. At the synapse, these signals convert into chemical messages to cross the gap between neurons. This process can either trigger or inhibit further action potentials. Repeated activity strengthens synapses, enhancing message transmission and enabling learning and adaptation.

How do neurons primarily communicate with each other?

• By light pulses

• Via sound waves

• Using both electrical and chemical signals

• Through magnetic signals

What is the term for the electrical signals that travel down a neuron?

• Action potentials

• Neural waves

• Synaptic pulses

• Chemical currents

What happens to an action potential when it reaches the synapse?

• It transforms into a chemical message

• It stops completely

• It becomes a magnetic signal

• It turns into a sound wave

What role do chemical messengers play at the synapse?

• They create new neurons

• They destroy old neurons

• They trigger or quiet action potentials in the next neuron

• They convert signals into light

How does repeated activity affect synapses?

• It weakens them

• It has no effect

• It makes them disappear

• It strengthens them

What is the result of synapses becoming stronger?

• The brain stops adapting

• Important messages are passed on more effectively

• Messages are more likely to be ignored

• Neurons become less active
