The parietal lobe is most involved in

GABA reuptake inhibitor (GRI)

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

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

An adult with a healthy sleep cycle is most likely to enter REM sleep

blocking receptors to prevent other neurotransmitters from binding to the neural receptors

Antagonists function by

Carl Wernicke discovered the region of the brain that is responsible for

Condition A included sentences such as "Strawberries are sweet," and Condition B included sentences such as "Strawberries are nervous."

Dr. Kovacs is conducting a study of how the brain responds to reading. He records subjects' brain activity using electroencephalography (EEG) while they read sentences. He is looking for the N400 signal, a negative EEG spike that occurs 400 milliseconds after someone processes something semantically surprising. There are two conditions in the study. The two figures below show average EEG activity for the subjects in the two conditions (Condition A on the left; Condition B on the right). The x-axis indicates time in milliseconds; time 0 indicates when the subjects first read the last word in each sentence. (A shows less squiggles around 400, B shows more)

GABA reuptake inhibitor

GRIs function by blocking the reuptake of gamma-aminobutyric acid (GABA), which means more GABA stays in the synapses and inhibits neurons from firing. This state is helpful in reducing seizures because seizures are caused by overactivity of neurons.

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

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

Because the connection between the right visual cortex and language center has been severed, split-brain patients are not able to retrieve the name of objects seen in the left visual field.

In a study mimicking Roger Sperry's work, Dr. Kornhauser compared the responses of split-brain patients against a control group of neurotypical participants. In his study, participants focused on a dot in the center of a computer screen and objects are presented in either the left or right visual field. After seeing the object, the participants named the object. The results of the experiment are presented below. (split brain: high accuracy in right visual field, low accuracy in left visual field control: even in both fields)

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

Josephine is more likely to be diagnosed with major depressive disorder than Abigail in response to a stressful or traumatic event.

Madeline has previously been diagnosed with major depressive disorder. She has an identical twin sister, Josephine, and a nonidentical sister, Abigail. Neither of Madeline's sisters have previously been diagnosed with major depressive disorder. Which of the following statements is true of Madeline's sisters?

parietal lobe for Group 1 and the temporal lobe for Group 2

Researchers trained monkeys to perform two tasks: an object-matching task and a location task. In the object-matching task, the monkeys are given an object and must choose a matching object from two objects placed in front of them. In the location task, an object is placed near one of two locations, and the monkeys must reach toward the location the object is closest to. Separating the monkeys into two groups, researchers created a lesion in one area of the brains of the monkeys in one group and a lesion in a different area of the brains of the monkeys in the second group. The researchers then tested the monkeys' performance on the two tasks. The figures below show the monkeys' accuracy on the two tasks. (group 1: higher object matching, low location group 2: high location, low object matching)

likely to be as similar and dissimilar to one another as are Vince's and Frankie's personalities (Identical twins raised apart have the capacity to be just as similar and dissimilar as twins raised together.)

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

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. (Neurons have an all-or-nothing response called an action potential, in which the neuron goes from being negatively charged at rest to being positively charged when it fires, then returning to its baseline negative.)

Which of the following describes what happens when a neuron sends a signal?

epinephrine
