Question 1

How many neurons does each person have?&#10;A) 100 million&#10;B) 128 thousand&#10;C) 33 billion&#10;D) 55 billion&#10;E) 86 billion

Accepted Answer

On average, each person has around 86 billion neurons in their brain.

Question 2

James called the way that our mind jumps from one thought to another:&#10;A) Overthinking&#10;B) Stream of consciousness&#10;C) The unconscious&#10;D) Daydreaming&#10;E) Mindless thought

Accepted Answer

James is referring to the literary technique known as "stream of consciousness," where a character's thoughts are depicted as a continuous flow without any clear structure or direction.

Question 3

The time frame for hormones to take effect is:&#10;A) Minutes to hours&#10;B) Hours to days&#10;C) Minutes to months&#10;D) Second to days&#10;E) Seconds to months

Accepted Answer

D

Question 4

In individuals with PTSD (post-traumatic stress disorder), a mildly fearful stimulus produces an overreactive:&#10;A) Hypothalamus&#10;B) Thalamus&#10;C) Amygdala&#10;D) Hippocampus&#10;E) Cingulate gyrus

Accepted Answer

The amygdala is responsible for processing and regulating emotional reactions, particularly fear and anxiety. In individuals with PTSD, the amygdala becomes overactive and responds to even mildly fearful stimuli with an exaggerated fear response. This leads to hypervigilance, avoidance of triggering situations, and other symptoms of PTSD.

Question 5

Which area of the brain is involved in the smooth movement of our bodies?&#10;A) Hindbrain&#10;B) Midbrain&#10;C) Pons&#10;D) Medulla&#10;E) Cerebellum

Accepted Answer

The cerebellum is located in the hindbrain and is responsible for coordinating and regulating movements, including fine motor skills and balance. It receives and processes sensory input from various parts of the body to ensure smooth and coordinated movements.

Question 6

A map of neural connections in the brain is known as a:&#10;A) Connectome&#10;B) Brainbow&#10;C) Pictogram&#10;D) Histogram&#10;E) Brain-ray

Accepted Answer

A map of neural connections in the brain is known as a connectome. The term was first coined in 2005 by Olaf Sporns to describe the idea of creating a comprehensive map of the neural connections in the brain, similar to a genome sequence. The development of new imaging techniques and computational methods has made it possible to create increasingly detailed connectomes, which has led to new insights into brain function and dysfunction.

Question 7

What does the f in fMRI stand for?&#10;A) Fractional&#10;B) Functional&#10;C) Follicle&#10;D) Frequency&#10;E) Factorial

Accepted Answer

The f in fMRI stands for "functional," as it measures changes in brain activity associated with different mental processes.

Question 8

This type of scan involves using a radioactive tracer:&#10;A) MRI&#10;B) fMRI&#10;C) PET&#10;D) EEG&#10;E) MEG

Accepted Answer

PET (Positron Emission Tomography) scans involve the use of a radioactive tracer, such as a sugar or protein, which is injected into the bloodstream. As the tracer travels to different parts of the body, it emits gamma rays that can be detected by the PET scanner, creating a 3D image of the area being examined. This type of scan is often used to detect cancer, brain disorders, and heart disease.
