A presynaptic neuron in the cerebrum transmits information to hundreds of other neurons. This process is an example of (a) convergence (b) divergence (c) temporal summation (d) spatial summation (e) a graded potential
The release of a neurotransmitter from a terminal button produces an inhibitory postsynaptic potential (IPSP) in the postsynaptic neuron. What is the most likely mechanism by which this occurs? A. the neurotransmitter opens chemically activated chloride channels B. the neurotransmitter activates a second messenger which then opens calcium channels C. the neurotransmitter is glutamate D. the neurotransmitter acts on a G-protein linked receptor which opens sodium channels
How do neurotransmitters directly affect the postsynaptic neuron? A)They cause a change in the electrical potential, exciting the neuron and causing it to fire b)They cause a change in the electrical potential, either exciting or inhibiting the next neuron. C)They cause a change in the electrical potential, inhibiting the neuron and stopping it from fi d)They connect with the appropriate receptor on the postsynaptic neuron
You reach for your smartphone and then put it down. You reach for it again but different neurons were activated for the same movement. This is an example of _________. A.neuroplasticity B.allostasis C.saltatory conduction D.degeneracy
In chemical synapses, transmission occurs in a forward direction because :-a- neurotransmitter receptors are found only in the postsynaptic membraneb- the subsynaptic membrane does not contain neurotransmitter vesiclesc- the subsynaptic membrane is more sensitive than the membrane of synaptic knob to the effect of neurotransmittersd- the subsynaptic membrane contains both ligand-gated and voltage-gated ionic channels
Sense of smell, also known as olfaction, is the ability to perceive and interpret odours.

In the hippocampus, when glutatmate is released into the synaptic cleft, but the postsynaptic cell is NOT depolarized, there is only a small postsynaptic response. Why is this the case? A. Ca++ ions block the NMDA ion channel B. Mg++ ions block the NMDA ion channel C. Glutamate is an inhibitory amino acid neurotransmitter D. There are no NMDA receptors on the postsynaptic cell
Which of the following is the role of axonal Calcium (Ca2+) channels in neuronal communication at the synapse? a) they inhibit the action potential causing it to stop b) Calcium channels have no role in this process c) by allowing calcium to exit the cell, they promote the propagation of action potential across the synapse by creating depolarization d) by blocking calcium entrance, they mediate the contraction of presynaptic axon to facilitate movement e) when they open, calcium enters the presynaptic terminal, promoting fusion of neurotransmitter vesicles with presynaptic membrane, and release of neurotransmitters to the synaptic cleft
Of the below, what do neurotransmitters do? stimulate presynaptic terminals. remain in the synaptic cleft for long periods of time. do not affect membrane channels in the postsynaptic membrane. bind irreversibly to the receptor molecules of the postsynaptic membrane. cause the production of action potentials in the postsynaptic membrane.
