Question 1

By electrically stimulating specific _______________ areas with electrodes, researchers can study the behavioral effects.

Accepted Answer

Researchers can study behavioral effects by electrically stimulating specific areas of the brain with electrodes, as the brain is responsible for processing and regulating behavior.

Question 2

The _______________ uses electrodes placed on the scalp to record the brain's electrical activity.

Accepted Answer

EEG, or electroencephalogram, is the technique that involves placing electrodes on the scalp to record the brain's electrical activity.

Question 3

The _________________ provides three-dimensional, highly detailed views of the brain using electrical signals generated by the brain in response to magnetic fields.

Accepted Answer

MRI (Magnetic Resonance Imaging) scanner uses magnetic fields and radio waves to generate detailed images of the brain and other parts of the body, including three-dimensional views. Unlike EEG (Electroencephalogram) which measures electrical activity of the brain, or ECG (Electrocardiogram) which is used for heart activity, MRI provides a more detailed structural imaging. CAT (Computed Axial Tomography) scan also provides detailed images but through X-rays, not magnetic fields.

Question 4

A new technique that takes a rapid series of brain images that are then put together by a computer to produce clear, sharp "movies" of brain activity is called________________.

Accepted Answer

Functional MRI (fMRI) is a technique that measures and maps the brain's activity by detecting changes associated with blood flow. This method allows for the creation of dynamic images, effectively producing "movies" of the brain in action, which is not a capability of traditional MRI, CAT scans, or EEG.

Question 5

The ___________________ provides color coded images of the brain's activity by measuring the amount of glucose used in different brain regions.

Accepted Answer

The PET scan (Positron Emission Tomography scan) provides color-coded images of the brain's activity by measuring the amount of glucose used in different brain regions, indicating areas of high and low activity.

Question 6

The ___________________ includes the hindbrain and the midbrain which are located at the base of the brain.

Accepted Answer

The brainstem consists of the midbrain, pons, and medulla oblongata, and it connects the rest of the brain with the spinal cord, performing critical functions in controlling the heart, breathing, and consciousness.

Question 7

The __________________ connects the spinal cord with the rest of the brain.

Accepted Answer

The hindbrain, specifically the brainstem, connects the spinal cord with the rest of the brain.

Question 8

The three structures that make up the ________________ are the medulla, pons and cerebellum.

Accepted Answer

The medulla, pons, and cerebellum are structures that make up the hindbrain, which is responsible for various functions including motor movements, balance, and autonomic processes.

Question 9

The ____________________ controls vital life functions such as breathing, circulation and muscle tone.

Accepted Answer

The answer of The ____________________ controls vital life functions such...

Question 10

The _________________ connects other regions of the brain to the cerebellum which helps coordinate and integrate movements on each side of the body.

Accepted Answer

The Pons is a part of the brainstem that links the medulla oblongata and the thalamus. It plays a crucial role in relaying messages between various parts of the brain, especially the cerebellum, thereby helping in coordinating and integrating movements on each side of the body.

Question 11

The brain structure that is part of the brain stem and is an important relay station that helps coordiante auditory and visual information before sending it on to higher brain centers is called the ___________________.

Accepted Answer

The midbrain is a part of the brainstem that acts as a major relay station for auditory and visual information, coordinating these sensory inputs before they are sent to higher brain centers for further processing.

Question 12

The __________________ is involved in motor control and contains a large concentration of neurons that produce dopamine.

Accepted Answer

The substantia nigra is a part of the brain involved in motor control and contains a high concentration of dopamine-producing neurons, which are crucial for movement regulation.

Question 13

The outer portion of the forebrain is called the _____________________ which is divided into two cerebral hemispheres.

Accepted Answer

The outer portion of the forebrain is known as the cerebral cortex, which is divided into two cerebral hemispheres. This area is responsible for many complex brain functions including memory, attention, perceptual awareness, thought, language, and consciousness.

Question 14

A thick bundle of axons called the __________________ connects the two hemispheres and serves as their primary communication link.

Accepted Answer

The corpus callosum is the thick bundle of axons that connects the two hemispheres of the brain, facilitating communication between them.

Question 15

The __________________ lobe is near the temples and contains the primary auditory cortex and is where the auditory information is received.

Accepted Answer

The temporal lobe is located near the temples and is responsible for processing auditory information, as it contains the primary auditory cortex.

Question 16

The ___________________ lobe is involved in processing somatosensory information, such as touch, temperature, body position and temperature.

Accepted Answer

The parietal lobe is responsible for processing somatosensory information, which includes sensations like touch, temperature, and the perception of body position.

Question 17

The ____________________ lobe processes voluntary movement and is involved in anticipatory thinking, planning, and emotional expression and control.

Accepted Answer

The frontal lobe is responsible for processing voluntary movement and is involved in functions such as anticipatory thinking, planning, and emotional expression and control.

Question 18

The __________________ are involved in processing and integrating sensory and motor information, language, abstract reasoning, creative thought, and the integration of perceptions and memories.

Accepted Answer

Association areas in the brain are responsible for integrating and processing sensory and motor information, as well as higher functions such as language, abstract reasoning, creative thought, and the integration of perceptions and memories.

Question 19

The prefrontal association cortex is involved in the ____________________________.

Accepted Answer

The prefrontal association cortex is primarily involved in the planning of voluntary movements, decision making, and personality expression. It does not directly process somatosensory, auditory, or visual information; those functions are handled by other specific areas of the brain.

Question 20

The _____________________ consists of the hypothalamus, hippocampus, amygdala and thalamus.

Accepted Answer

The limbic system includes the hypothalamus, hippocampus, amygdala, and thalamus, and is involved in emotion, memory, and arousal.
