Synaptic transmittion 0.0 / 5 ? PsychologyApproachesASAQA Created by: ThucydidesCreated on: 17-05-18 00:18 what is the process by which the synaptic vesicles release the neurotransmitters across the synaptic gap? exocytosis 1 of 10 what produces the exitatory or inhibitory impulses? the Receptor molecules - after being bound to certain neurotransmitters 2 of 10 what determines how long the effects of the neurotransmitters are? the speed of re uptake 3 of 10 How are neurotransmitters turned off? by enzymes produced in the body 4 of 10 If an exitatory neuro tranmitter binds to a receptor site what happnens? It sends an electric charge through the cell membrane creating excitatiory post synaptic potential EPSP 5 of 10 what does IPSP stand for inhibitory synaptic potential 6 of 10 can a neerve cell recive booth EPSPs and IPSPs at the same time? yes 7 of 10 What is spatial summation? large numbers of EPSPs generated across multiple synapses increasing the chance of exitatory sinaptc tansmittion 8 of 10 What is temporal summation? the generation of large number EPSP's at one synapse by multiple action potential signalsif exitatory 9 of 10 What happens if exitatory synapses are more active what happens? the cell fires at a higher rate 10 of 10
