In what form do messages start as they are transmitted down the neuron?
Press to flip
As electrical signals or action potentials.
What initiates an action potential?
Electrical signals in the neuron.
What term describes the initial electrical signals in neurons?
Action potentials
What effect can chemical messengers have on the next neuron?
They can either trigger or quiet an action potential.
Why is the strengthening of synapses important?
It is vital for learning and adapting.
How do action potentials transmit messages across the synapse?
Action potentials transform into chemical messages to cross the gap.
Through what types of signals do neurons communicate?
Electrical and chemical signals
What physiological changes occur with repeated neuronal activity?
Synaptic strengthening.
Describe one mechanism essential for learning and memory in neurons.
The strengthening of synapses through repeated activity.
What is the function of action potentials?
They travel rapidly down a neuron to relay messages.
What transition occurs at the synapse during neuron communication?
The transition from electrical signals (action potentials) to chemical signals (messengers).
What is the term for the gap between two neurons?
Synapse
What are the roles of chemical messengers in neuron communication?
They transmit signals across the synapse and regulate action potentials in the next neuron.
How does a stronger synapse affect message transmission?
It makes message transmission more likely.
What happens to the synapse with repeated activity?
It strengthens.
