The N-methyl-D-aspartate (NMDA) receptor complex in brain is a glutamate receptor subtype with several recognition sites including a glycine site that is able to modulate and activate allosterically the receptor. This receptor may be important in the regulation of developmental synaptic plasticity. The release of glutamate and consequent overstimulation of(More)
1. Homogenates of human infant and adult temporal cortex were used to measure [3H]-TCP and [3H]-MK-801 binding to the N-methyl-D-aspartate (NMDA)-coupled ion channel phencyclidine site. 2. Both [3H]-TCP and [3H]-MK-801 binding increased in infant cortex by > 100% between term and 26 weeks suggesting that the numbers of NMDA receptors increase during(More)
An instructor's quest to express her personality and passion for teaching in an online course, without compromising academic rigor, led to the creation of a five-step instructional development model. This article describes the process from inception to assessment in the context of an online Histology course and provides a guide for others considering(More)
Polyamines regulate cell division in developing brain. Neuronal membranes and the NMDA receptor have polyamine binding or functional sites. We have visualized [3H]spermidine binding in human cerebellum sections. Autoradiographs showed high specific [3H]spermidine binding in granule cell layer and low binding in molecular layer in neonate, infant and adult(More)
In vitro autoradiography and test-tube assay of the sodium-dependent binding of D-[3H]aspartate were used to localize and quantify the uptake site for the excitatory amino acid neurotransmitters glutamate and aspartate in the cerebellar cortex of human cerebellar hemispheres. Autoradiograms revealed a pronounced heterogeneity in the distribution of(More)
The binding of D-[3H]aspartate to the specific uptake site for the excitatory amino acids glutamate and aspartate was measured in homogenates of temporal lobe cortex taken at postmortem from 76 human infant and adult brains. Binding levels were very low in brains of preterm and term infants but increased rapidly during the first 20 postnatal weeks to reach(More)
