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

Compare and contrast electroencephalograms and event-related potentials, describing how each arises and their electrophysiological bases. What abnormal conditions can they be used to diagnose?

Spontaneous electrical rhythms that can be recorded from the surface of the scalp

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

Refer to the figure. This figure depicts the process of

Loss of consciousness and symmetrical involvement of the body are characteristic of _______ seizures.

Which process is not involved in chemical synaptic transmission?

Whether a synapse is excitatory or inhibitory is determined by the

Muscarine and nicotine mimic the action of

Otto Loewi's experiments showed that the _______ releases acetylcholine, which _______.

The myelin sheath that encases some axons is interrupted by _______, small gaps spaced about every millimeter along the axon.

Describe the function of two kinds of acetylcholine receptors. Explain how specific exogenous ligands affect each receptor type.

The _______ is the site at which the action potential is initiated.

Refer to the figure. This diagram illustrates
