In the correct order which way is visual information processed? correct answersphotoreceptors, ganglion cells, LGN cells, end-stopped cells A complex cell receives its input from several simple cells. When a light shines on the OFF region of the receptive field of one of the underlying simple cells, what will happen to the complex cell's response? correct answersanother simple cell that has light shining on the ON region of its receptive field will be excited, leading to an overall stronger ...

Which of these statements about the neuromuscular junction is accurate?Binding of acetylcholine to the nicotinic receptor on the motor end-plate causes an influx of Na+ and efflux of K+ through the receptor Which of these is not an example of primary active transport of ions across cell membranes?The sodium-glucose co-transporter on intestinal cells GABA is an inhibitory neurotransmitter that causes the membrane to hyperpolarize. From this information, what type of ion channel does GAB...

NSC 3361 Exam 1 Questions and Answers All Correct Sequence of transmission at chemical synapse - Answer-1. Action potential travels down axon to axon terminal. 2. Voltage-gated calcium channels open and Ca2+ enters. 3. Synaptic vesicles fuse with membrane and release transmitter into the cleft. 4. Transmitter binds to post-synaptic receptor, causing EPSP or IPSP. 5. May bind to the presynaptic autoreceptors, decreasing release. 6. Neurotransmitter is inactivated by degradation or reuptak...
