Morphologic and electrophysiologic maturation in developing dentate gyrus granule cells

Dentate gyrus granule cells from immature (7-28 days) Sprague-Dawley rats were examined with whole cell patch clamp recordings and biocytin filling in in vitro hippocampal slice preparations. Although recordings were confined to the middle third of the suprapyramidal limb of the dentate, the granule cells exhibited marked variability in their physiologic properties: input resistance (IR) ranged from 250 MOmega to 3 GOmega, and resting membrane potential (RMP) from -82 to -41 mV. Both IR and RMP were inversely correlated with dendritic length, a morphometric indicator of cell maturity. Thus the highest IR cells were the youngest, and maturation was characterized by a progressive decrease in IR, hyperpolarization of RMP, and elongation of the dendritic arbor. When cells were grouped by IR, significant intergroup differences were found in RMP, dendritic length, and number of dendritic terminal branches. Although cells of all IR categories were examined throughout the age spectrum under study, none of the inter-IR group differences was age-dependent. These data suggest that IR provides a reasonable estimate of granule cell maturity and that maturation entails predictable changes in cell properties and morphology. These aspects of maturation correlate with each other, are independent of animal age, and most likely proceed according to a program related to cell birth.     

Physiology and pharmacology of native glycine receptors in developing rat ventral tegmental area neurons

Properties of whole-cell glycine-activated currents (I(Gly)) of neurons freshly isolated from ventral tegmental area of rats between postnatal day (P) 0 and 40 (P0-P40) were examined using the gramicidin-perforated patch technique. I(Gly) was present throughout the period of investigation and displayed age-related alternations in its kinetics, reversal potentials (E(Gly)) and sensitivity to antagonists. During development, the time constant for desensitization of I(Gly) decreased about two-fold, and the E(Gly) shifted to more negative potentials. Specifically, E(Gly) was -29 mV in neonatal (P0-P7) and decreased to -50 mV in adult (P24-P40) neurons. While the neonatal glycine receptors (GlyRs) are resistant to strychnine, the adult GlyRs are sensitive to STR. The values for 50% inhibition (IC(50)) of I(Gly) was 110 and 12 nM in P0-P3 and P24-P40 neurons, respectively. Picrotoxin, on the other hand, was more effective in blocking neonatal neurons. The IC(50) values were 17 and 231 microM for the neonatal and adult neurons, respectively. These observations are discussed in terms of developmental changes of subunit composition of GlyRs and of intracellular Cl(-) concentrations.
