Exam 6: Physiological Analysis-Nerve Cells and Behavior

The long cable like neurite that transmits information to other neurons is called a(n)

The small storage sacs containing the neurotransmitter in the presynaptic neuron are called

Which of the following statements regarding auditory and visual input in the barn owl is TRUE?

When the wavelength of a sound equals the head width of an animal, the sound is

For many species, neurons fire only if they meet a certain threshold. In other words, these neurons do not emit a partial response. This describes the

A process that results in the elevation of response of a postsynaptic neuron for minutes or hours is called

The area of the nervous system that determines whether the message of one neuron will generate an action potential in the next neuron is the

During the resting potential

Nottebohm (1965), in his study of the neurology of birdsong, made use of the fact that new neurons will incorporate chemical markers when they make DNA in preparation for cell division, but that old neurons do not, because they do not synthesize DNA. This information allowed him to demonstrate that

Although electrical synapses are much less common than chemical synapses, they are known for their speed of transmission and, thus, are most likely part of the neural circuitry that underlies

The intensity of a stimulus, e.g., the difference between a dim light and a bright light, is coded

Dupret and colleagues (2007), studying rats in a water maze test that makes use of a hidden platform, have found that spatial learning depends on

Electrical synapses differ from chemical synapses in that electrical synapses

An afferent neuron

Cockroaches run when exposed to a gust of wind from a predator, yet they ignore the wind that they create themselves when they walk. Plummer and Camhi (1981) were able to demonstrate that this happens because

A nerve impulse (action potential) is caused initially by the

Binaural comparison contributes to locating the source of a sound by allowing an organism to compare differences in

There is a correlation between the timing of the addition of new neurons to the affected song center and the song learning sequence in male zebra finches. This leads us to conclude that

What behavior is a noctuid moth most likely to display when its A1 auditory receptor cell is stimulated?

Roeder (1967) determined that the noctuid moth has two auditory receptors, A1 and A2, for each of its two ears. Which of the following statements about the receptors is TRUE?
