Zusammenfassung der Ressource
action potential
- information carried between neurons chemically -
neurotransmitters - within neurons electrically
- sensory neurons send information to CNS - tissue damage
triggers series of action potentials in group of neurons
- motor neurons send information
from CNS to muscles
- sudden brief change in electrical
resting voltage in cell and return - in
fraction of a second
- information encoded in 'frequency'
of a potential - very cold > cold so
more action potentials
- important role in understanding nervous sytem - way
of measuring how information is transmitted
- accurate measurement by comparing activation
with stable values at rest
