Exam 3: Neurons and Synapses

Sensory neurons use _____, rather than single spikes, to encode stimuli.

Many inotropic receptors allow only a particular type of ion to pass through.

The idea of neurons forming coalitions suggests that membership in particular groups is:

Myelin sheaths come in short segments. The gaps between the segments are referred to as:

When there are more ions outside of the neuron than inside the neuron, they may be driven inside because of the:

The axon hillock is the part of the neuron that starts:

Local coding is more versatile than population coding.

Neurotransmitter is released into the synaptic cleft after:

Action potentials can move both forward and backward in a neuron.

Neurons communicate using both _______ and ________ signals.

Explain how an action potential is created and moves through the cell.

Information collected by the dendrites is sent to the soma for integration.

The role of calcium in action potentials is to:

An excitatory postsynaptic potential (EPSP) occurs when:

According to the population view, any given neuron may:

During saltatory conduction, action potentials _______ instead of _______.

Action potentials do not travel backward because of _____.

Neurons are connected to each other by dendrites.

Loss of myelination around axons would most likely affect:

When a psychoactive drug prevents the reuptake of a neurotransmitter, it should be classified as an _____ drug.
