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. The figure presents two line graphs, labeled A and B, each representing the EEG activity for the subjects with two conditions. The horizontal axis indicates the values 400 and 800. The vertical axis indicates the value, 0. A horizontal line extends across the graph at value 0. Negative values appear above the horizontal axis and positive values appear underneath the horizontal axis. In graph A, the EEG result fluctuates slightly above and slightly below the value of 0. In graph B, the EEG result also fluctuates slightly above and slightly below the value of 0, with a spike into the negative range occurring at 400 milliseconds. Which of the following pairs of conditions would produce results such as the ones Dr. Kovacs found? A Condition A included sentences such as "Strawberries are sweet," and Condition B included sentences such as "Strawberries is sweet." B Condition A included sentences such as "Strawberries is sweet," and Condition B included sentences such as "Strawberries are sweet." C Condition A included sentences such as "Strawberries are nervous," and Condition B included sentences such as "Strawberries are sweet." D Condition A included sentences such as "Strawberries are nervous," and Condition B included sentences such as "Strawberries are furious." E Condition A included sentences such as "Strawberries are sweet," and Condition B included sentences such as "Strawberries are nervous."

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. The figure presents a bar graph with four bars of data. Two categories are listed on the horizontal axis: Group 1 and Group 2. A key indicates that both categories contain data for object matching and location. The vertical axis is labeled, Accuracy, and the numbers 0 through 1.0, in increments of 0.2, are indicated. The data represented in the bar graph are as follows. Note that all values are approximate. Group 1, Object Matching; Accuracy, 0.95. Group 1, Location; Accuracy, 0.48. Group 2, Object Matching; Accuracy, 0.55. Group 2, Location; Accuracy, 0.90.

Yes
Say yes to pass the question how are genes and behavior linked? Charles Darwin's theory of evolution explains behavior as the result of natural selection. Variation among individuals and competition for resources lead to survival of the most adaptive behavior and features. This principle underlies human behavior, as well as that of other animals. Research in genetics has clarified for the biological basis for natural selection and inheritance. Our chromosomes contain thousands of genes, carrying traits inherited from our parents. Each gene consists of a DNA segment that encodes for a protein. Proteins, in turn, serve as the building blocks for the organism's structure and function, including the functioning of the brain. While a draft of the human genome was recently completed, we do not yet know precisely how specific genes influence behavior and mental processes.
Yes
Say yes to pass the question how does the body communicate internally? the body's two communication systems are the nervous system and the endocrine system. the neuron, the basic unit of the nervous system, is specialized for processing information. It receives messages by means of stimulation on the dendrites and soma and, when sufficiently aroused, generates an action potential along the axon. neurotransmitter chemicals relay the message to receptors on cells across the synapse The nervous system, composed of billions of interconnected neurons, has two main divisions: the central nervous system (the brain and the spinal cord) and the peripheral nervous system. The peripheral nervous system, in turn, can be divided into the somatic nervous system (further divided into sensory and motor pathways) and the autonomic nervous system, which communicates with the internal organs and glands. The somatic division of the autonomic NS is most active under stress, while the parasympathetic division attempts to maintain the body in a more calm state. The glands of the slower endocrine system also communicates with cells around the body by secreting hormones into the blood stream. It's activity is controlled by the pituitary gland attached to the base of the brain, where it receives orders from the hypothalamus. Psychoactive drugs affect the nervous system by influencing the effects of neurotransmitters. Moreover, they may act as a agonist or antagonist. Unfortunately for drug users, many neural pathways in the brain may employ the same neurotransmitter, causing unwanted side effects.
yes
Say yes to pass the question how does the brain produce behavior and mental processes? Early medicine learned about the brain from the study of brain injured persons, such as Phineas Gage. In modern times, researchers have opened windows on the brain, using the electroencephalogram to sense the brains electrical activity, along with electric probe sometimes used to stimulate the brain during surgery. In recent years, computer technology has led to brain-scanning techniques, such as CT, PET, MRI, and FMRI-each having its advantages and disadvantages. We can' conceive of the brain as being organized in three integrated layers. The brain stem and associated structures (including the medulla reticular formation Pons thalamus and cerebellum) control many vital body functions, along with influencing alertness and motor movement. The limbic system (including the hippocampus, amygdala, and hypothalamus) plays vital roles in motivation, emotion, and memory. The cerebral cortex contains highly specialized modules-each with distinct functions. It's frontal lobe's involve both motor functions and higher mental functions. The parietal lobes specialize in sensation, especially the senses of touch and body position. the occipital lobes deal exclusively with vision, while the temporal lobe's have multiple roles involved in vision, hearing, and smell. Even though the functions of the brain are highly localized within specific modules, they normally work seamlessly together. The two cerebral hemispheres are also differently specialized. Language, analytical thinking, and positive emotions are regulated by specific parts of the left hemisphere, while circuits in the right hemisphere control spatial interpretation, visual and musical memory, and negative emotions. If the hemispheres are surgically severed, as when the corpus callosum is cut and split brain patients, a duality of consciousness emerges. In such cases, each hemisphere functions independently and has no direct awareness of stimulation or cognitive activities affecting the other. In people with intact brains, however, the two hemispheres communicate and cooperate with each other.

n 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. The figure presents a bar graph with four bars of data. Two categories are listed on the horizontal axis: Split-brain and Control. A key indicates that both categories contain data for the left visual field and right visual field. The vertical axis is labeled, Accuracy, and the numbers 0 through 100, in increments of 10, are indicated. The data represented in the bar graph are as follows. Split Brain, Left Visual Field; Accuracy, 5. Split Brain, Right Visual Field; Accuracy, 90. Control, Left Visual Field; Accuracy, 90. Control, Right Visual Field; Accuracy, 90. What is the most appropriate conclusion Dr. Kornhauser can draw from the results? A Split-brain patients cannot process objects using the right half of their brain and thus are not able to identify the objects in the right visual field. B Split-brain patients have a much faster reaction time to objects in the right visual field due to having a more direct connection between the visual cortex and their language center. C Because the connection between the left visual cortex and language center has been severed, split-brain patients are not able to retrieve the name of objects seen in the right visual field. D 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. E Because accuracy in the control group was low, the objects he used were likely too difficult for the participants.
