Synaptic Transmission. In a chemical synapse, the pre and post synaptic membranes are separated by a synaptic cleft, a fluid filled space. The chemical event is involved in the transmission of the impulse via release, diffusion, receptor binding of neurotransmitter molecules and unidirectional communication between neurons. The neurotransmitter termination can occur in three ways - reuptake, enzymatic degradation in the cleft and diffusion.
Pride in Accomplishment: The Interstate H-3 Project. Hawaii, America's 50th state, is known around the world for gentle trade winds and tropical beauty. While Hawaii takes pride in these natural wonders, we are also proud of our human achievements. One truly spectacular accomplishment is the completion of the Interstate H-3 freeway on the island of Oahu. H-3, 37 years in the making, was officially opened on Dec.12, 1997.
The Colorado Department of Transportation ran a successful test of the $78 million toll lane on Dec. 13. The I-70 mountain corridor, which feeds businesses in Idaho Springs and other mountain communities, has been the focus of state transportation officials for several years. CDOT crews expanded the eastbound approach to the Veterans Memorial Tunnels â formerly the Twin Tunnels â to three lanes in 2013.
