SCANS
An amplified recording of the electrical waves sweeping across the brain's surface. It shows the brain's functioning.
EEG scan
What are the 3 parts of the brain? Whats their function?
Hindbrain: controls basic life functions, Midbrain: motor control, Forebrain: voluntary actions, thinking, and processing.
These are segments of DNA that code for specific traits or proteins
Genes
The biological clock that regulates your sleep-wake cycle over a 24-hour period.
Circadian rhythm
Creates cross-sectional images of the brain. It shows its structure, NOT its function.
CAT scan
Which part of the peripheral NS controls parasympathetic and sympathetic functions?
Autonomic
2 areas located in the left temporal lobe which give us the ability to speak and understand language
Brocas area and Wenickes area
This molecule carries the genetic information that makes up chromosomes.
DNA
Which stage of sleep do you regularly experience hypnic jerks (sudden twitches)?
Stage 1
Visual display of the brain that detects a radioactive form of glucose while the brain performs a given task. It shows a function.
PET scan
The neurotransmitter that causes pleasure and controls voluntary movement
Dopamine
What are the 4 lobes of the brain and their functions?
Frontal lobe: thinking and doing
Parietal lobe: sensing touch and space
Occipital lobe: seeing
Temporal lobe: hearing and memory
This term describes the complete set of genetic material in an organism.
Genome
The stage where dreaming occurs and your brain is highly active, but your body is paralyzed to prevent acting out dreams.
REM sleep
It produces images while performing a task. Shows structure AND function
Neurotransmitter known as the "pain killer"
Endorphins
Which hemisphere of the brain controls creativity, and which controls logic?
Left = logic
Right = creativity
These are twins that develop from a single fertilized egg and share 100% of their genes.
identical (monozygotic) twins
Name me 3 types of sleep disorders
Insomnia: Difficulty falling asleep or staying asleep.
Sleep Apnea: Breathing stops and starts during sleep.
Narcolepsy: Sudden and uncontrollable sleep attacks.
Sleepwalking: Getting up and walking around while asleep.
Night Terrors: Intense fear during sleep, typically in deep sleep stages.
Its the study of the magnetic fields generated by the brain through neural activity. Shows brain functioning.
EMG scan
Name 5 neurotransmitters
Dopamine, Serotonin, Acetlycholine, Norepinephrine, GABA, Endorphins
Name all the cortexes of the brain
Motor cortex
Somatosensory cortex
Visual cortex
Auditory cortex
Prefrontal cortex
Association cortexes
This type of study helps researchers estimate the heritability of traits by comparing twins raised together vs. apart.
twin studies
What is Activation-Synthesis Theory, Information Processing Theory, and cognitive Development Theory?
Activation-Synthesis Theory: Dreams are just the brain’s attempt to make sense of random brain activity during sleep.
Information Processing Theory: Dreams help process and organize memories from the day.
Cognitive Development Theory: Dreams are part of cognitive development and reflect our thinking, problem-solving, and understanding of the world.
