Physiological properties of CA1 pyramidal neurons recorded from young and aged rats

IR, MΩ RMP, mV Sp Amp, mV
Young (n = 12) 37.0 ± 2.5 −62.8 ± 1.5 80.6 ± 1.9
Aged (n = 40) 37.8 ± 1.1 −61.9 ± 0.6 82.8 ± 0.7
  • The values for input resistance (IR), resting membrane potential (RMP), and spike amplitude (Sp Amp) are indicated as mean ± SE. The number in parentheses indicates the number of cells from the young and aged animals.
