Exam 3: Neurophysiology: The Generation, Transmission, and Integration of Neural Signals

Explain the events that occur at the axon hillock to trigger an action potential.

A ligand is a

Transporter molecules are involved in the _______ of neurotransmitter at the synapse.

After release, neurotransmitters are deactivated in the synapse by

Inhibitory postsynaptic potentials are characterized by _______ the postsynaptic membrane.

Discuss how an action potential can be likened to a toilet. Highlight each component of the action potential and the aspects of flushing to which each corresponds.

Action potentials generally are not propagated along dendrites because dendrites usually have few

Event-related potentials are particularly useful for diagnosing problems with _______ at birth.

Action potentials are all-or-none phenomena. This means that

After the spike of an action potential, axons may exhibit small potential changes, called

Neurophysiology is the study of

Which statement regarding ions is true?

A key causal event in the release of neurotransmitter molecules from vesicles into the synaptic cleft is the

The early components of event-related potentials are associated primarily with

Describe some of the mechanisms by which the actions of neurotransmitters are stopped rapidly. Why is this process important?

Research is currently underway into _______ as a potential treatment for seizures.

During the process of _______, transmitter molecules are reabsorbed by the same axon terminal that originally released them.

Nicotine, which acts like a transmitter at a receptor, is referred to as an _______ of that receptor.

Complex partial seizures are often preceded by an unusual sensation referred to as

Give a detailed explanation of how the resting membrane potential is established and how it is maintained.
