AP Psych Unit 2

A person whose body is producing too much testosterone is most likely to exhibit

overly aggressive behavior

Antagonists

Block receptors

The Parietal Lobe

Controls processing sensory information

Which hormone is released when a person is under stress?

Cortisol

Agonists

Increase the effectiveness of a neurotransmitter at the receiving neuron.

If a body does not have enough potassium, how might that affect neuronal firing?

The neurons will struggle to fire because there will not be enough positively charged ions to trigger the firing of the neuron.

A neuron sends a signal along its

axon

The medulla oblongata is a part of the

brain stem

The hormone most associated with the fight or flight response is

epinephrine

A person whose body is not producing enough testosterone is most likely to exhibit

fatigue

Johnny often hits his brother even though his brother does not do anything to antagonize him. Johnny's aggression is most likely due to a combination of

his genetic makeup, the environment he grew up in, and the fact that aggression can be evolutionarily adaptive

At a synapse, neurotransmitters released by the sending neuron do which of the following?

They bind to receptors at the receiving neuron, which opens ion channels.

Carl Wenickle

Discovered the part of the brain that's responsible for language comprehension

A drug that is used to treat seizures functions by preventing inhibitory neurotransmitters from returning to the presynaptic neuron. This slows the rate of neurons firing by increasing the amount of the inhibitory neurotransmitter in the synapse. The drug is most likely to be classified as a

GABA

What does the Thalamus do?

It relays most sensory signals to the cortex.

Describes what happens when a neuron sends a signal.

The neuron goes from being negatively charged to briefly being positively charged, and finally returns to being negatively charged again. The magnitude of the negative charge is fixed regardless of the strength of the input signal it receives.

Ruth and Debbie are identical twins who were raised by the same family. Vince and Frankie are identical twins who were separated at birth and raised by different families. According to research on the heritability of personality traits, Ruth's and Debbie's personalities are statistically

likely to be as similar and dissimilar to one another as are Vince's and Frankie's personalities
