The membrane properties of cells within the pineal gland of guinea pigs were studied using intracellular electrophysiological techniques. The electrotonic responses to intracellular current injection decayed with a single exponential in approximately 60% of cells but was preceded by a quicker component in the remainder. The membrane time constant was 2.8 ms. Depolarization beyond -29 mV activated an outward current that reversed at around the value of the resting potential. Hyperpolarization… CONTINUE READING
