Brain Quiz Review

Question 1

What are Early Assumptions vs Mordern Understadnings of brain development

Answer 1

Believed that brain developement happens onlyin chilldhood but brain actually still grows during 20s adn 30s

Question 2

When does prefrontal cortex develope?

Answer 2

Start of puberty to when you become stable adult

Question 3

What is prefrontal cortex

Answer 3

HJelps with desciiosn making and impulse control. Biggest in animals

Question 4

What is an example of structural brain changes in teenagehood

Answer 4

Grey matter inceases in chidlhood. peeks in early teens and goes down in late teens. This is because of synaptic pruning which gets rid of unused synapes. Increases brain efficeny. Men peak later bcuz they start puberty later

Question 5

What is a medial prefonrotal cortex

Answer 5

Controls things like memory, emotion regualtion, desicions making. Commonly used in teens

Question 6

Drawbacks of only using medial prefonrotal cortex?

Answer 6

Lack of udnerstanding for others perspectives

Question 7

Why do teens take more risks?

Answer 7

Limbic system is more sensetive to dopamine which is gotten from risk taking behaviors. Prefrontal cortex is developing so there’s bad risk analysis

Question 8

What is CNS?

Answer 8

Central nervous system is brain and spinal cord - for analysze info like sight and sound

Question 9

What is PNS?

Answer 9

• Peripheral Nervous System
• Comtains neurons.
• There’s two types motor and sensory noeurons. motor heelps with movement and carries singals out from CNS.
• Sensory neurons gather info form 5 senses as brings singals to CNS

Question 10

What are action potientals

Answer 10

electric singals that nerve cells trasmit

Question 11

What are noeuron transmitters

Answer 11

Nerve cell transmits checmical signals

Question 12

What is synaptic connection

Answer 12

allows comms between nuerons

Question 13

What are interneurons

Answer 13

connectors between sensory and motor neurons

Question 14

How many neurons does brai have

Answer 14

86 billion neurons

Question 15

Synapes meaning

Answer 15

Connected between neurons. Nuerons have gaps for them called synaptic gap

Question 16

Whaat are Neurotransmitters

Answer 16

• Chemical messages.
• Transmit messages btwn neurons andnuerons to muscle.
• These are realased by CNS through synapes.
• Hormones released in endocrime sys.
• Hormones and nuerotramistters can be relaeased in the same gland

Question 17

What is adrenaline

Answer 17

Fight/flight

Question 18

What is noradrenaline

Question 20

What is Serotonin

Answer 20

Mood

Question 21

What is Endorphins

Answer 21

Euphoria

Question 22

What is Cerebrum

Answer 22

responsible for complex functions like thought, language, and movement, and is divided into two hemispheres connected by the corpus callosum

Question 23

What is cerebellum

Answer 23

Regualtes motor behaviors, posture and blaance. Has most nerve cells and accounts for 10% of brain’s weight)

Question 24

What is brain stem

Answer 24

Base of brain, regulates automatic functions like sleep cycle, breathing and digestion

Question 25

Explain nesting

Answer 25

Center part of brain does simpler tasks but are older like breathing and pumping blood (has white matter). Outer part becomes more complex like empathy and emotilan regulation (has grey matter)

Question 26

What are two hemispehre of brain connected by

Answer 26

Corpus callosum which is a band of neural fibers. They need brains to be connected because tasks require both parts of brain so comms between both sides is important

Question 27

WHat is limbic system

Answer 27

Regualte human behavior and processes memory+movitation

Question 28

What is Amygdala

Answer 28

Process fear and emotions. Instinct + movitational behavior (when someone punches you flinch). Fight/flight/freeze

Question 29

What is Hyptothalamus

Answer 29

Keeping body steady like regualting hunger, bod temp etc

Question 30

What is circandian rhythm

Answer 30

regualtes waking up to sleep cycle; contrlled by hyptothalamus

Question 31

What is hippocampus

Answer 31

Long term ememory - turns thigns into pernament memorry

Question 32

What is cerebral cortex

Answer 32

Outermost layer of cerebrum

Question 33

What is frontal lobe

What is Learning over Life cycle look like?

Answer 44

Child's brain focuses on needs and wants Teen's brain focuses on limbic system Adult's brain focuses on prefrontal cortex

Question 45

Question 49

Takeaways from mike's transplant

Answer 49

mike was blind since 4 because he never seen, his brain neve learned to use sight until he got eye surgery and can see seeing was hard because there's depth perception, shadows and other thigns to consider when seeing. he couldn't recongize his children therefore seeing is not just eyes but brain aswell
