What are the two main parts of the nervous system?
What are the Central Nervous System (CNS) and the Peripheral Nervous System (PNS)
This famous experiment involving dogs demonstrated the principles of classical conditioning.
What is Pavlov's dog experiment?
What is a cell of the brain called?
What is a neuron or glial cell?
You only use 10% of your brain.
What is false?
Brain imaging shows that all parts of the brain have a function, and even at rest, many areas are active. While you may not use all of it at once, you do use essentially 100% of your brain over time.
This disease involves plaques and tangles that damage memory and cognition.
What is Alzheimer’s disease?
What region of the brain is responsible for processing visual information?
What is the occipital lobe?
This phenomenon occurs when people fail to help in an emergency if others are present.
What is the bystander effect?
The junction between two neurons where signals are transmitted.
What is a synapse?
REM sleep is the stage of sleep when most dreaming happens.
What is true?
What disease is associated with a loss of dopamine and excessive tremors?
What is Parkinson’s Disease?
This type of injury often blocks communication between brain and body, resulting in paralysis from the waist down.
What is a spinal cord injury?
The founder of psychoanalysis who emphasized the role of the unconscious mind.
Who is Sigmund Freud?
The electrical signal that travels down a neuron’s axon.
What is an action potential?
The left hemisphere controls the left side of the body.
What is false?
The left hemisphere of the brain primarily controls the right side of the body (and vice versa). This is because motor and sensory pathways cross over in the brainstem.
This condition is caused by abnormal electrical activity in the brain, leading to seizures.
What is epilepsy?
This structure in the limbic system processes fear and emotions.
What is the amygdala?
What is the colloquial term for the heightened activation of the sympathetic nervous system?
Answer: What is the "fight or flight" response?
The brain’s ability to reorganize, change, and adapt to new experiences.
What is neuroplasticity?
The brain mostly stops developing when the prefrontal cortex matures in one’s late twenties.
What is false?
While structural maturation largely finishes by the mid-late twenties (often marked by the maturation of the prefrontal cortex), the brain continues to develop through lifelong neuroplasticity and functional development.
This autoimmune disease attacks the myelin sheath of neurons.
What is multiple sclerosis (MS)?
This part of the midbrain that produces dopamine, when degenerated, is stimulated with surgically-implanted electrodes as a treatment for Parkinson’s disease.
What is the substantia nigra?
This type of amnesia makes it hard to form new memories after brain injury.
What is anterograde amnesia?
These cells support neurons, provide insulation, and nutrition.
What are neuroglia or glial cells?
The quintessential function of dopamine is to signal pleasure and reward.
What is false?
While dopamine plays roles in motivation, learning, and reward prediction, its most fundamental and essential function is to control voluntary movement. This is why a lack of dopamine is associated with Parkinson’s Disease.
This progressive neurodegenerative disease is also known as Lou Gehrig’s disease.
What is ALS (amyotrophic lateral sclerosis)?
