Electrochemical Basis of Behavior Flashcards
This is a recording device that connects to an OSCILLOSCOPE.
Millivoltmeter
This is the difference in charge on the two sides of the membrane of an axon.
Polarization
These ions are found OUTSIDE of a neuron during RESTING POTENTIAL.
Na+ (Sodium)
Cl- (Chloride)
These ions are found INSIDE of the membrane of a neuron during RESTING POTENTIAL.
Anions (large negative protein)
K+ (potassium)
RESTING POTENTIAL of a neuron is regulated by ___________.
Sodium Pump
The POSITIVE charge OUTSIDE of the neuron is due to ___________.
Sodium
The NEGATIVE charge INSIDE of the neuron is due to _____________.
Anions
During ACTION POTENTIAL, SODIUM ions___________ and POTASSIUM ions__________.
Sodium RUSHES IN
Potassium is ALREADY in
During ACTION POTENTIAL, the ANIONS __________ and the CHLORIDE ions __________.
Anions CANNOT GET OUT
Chloride STAYS OUTSIDE
POTASSIUM DIFFUSING out is a(an) ___________ process.
Passive
SODIUM and POTASSIUM ions being PULLED into the cell is a(an) ___________ process.
Active
DEPOLARIZATION has a recording of ___mV to ___mV.
- 70 to 0
* See illustration in notes*
REVERSE POLARIZATION has a recording of ___mV to ___mV.
0 to +30
See illustration in notes
This is the INCREASE in EXCITABILITY as a neuron moves TOWARD the THRESHOLD.
