Unit 1a: Brain Flashcards
Medulla
Breathing: The medulla controls the rate, depth, and rhythm of respiration
Pons
Alertness: The pons sets the body’s alertness level when waking up
Reticular Formation
when a person can sleep through loud traffic in a large city, but is awakened promptly by the sound of an alarm or crying baby
Cerebellum
the cerebellum plays a role in learning to ride a bicycle or play a musical instrument
Limbic System
involved when you need to eat
Thalamus
keeping you awake and alert
Amygdala
producing a loud banging noise
Hippocampus
learning how to memorize speeches or lines in a play
Cingulate cortex
Hypothalamus
if melatonin is released at the wrong time, we can have trouble falling asleep
Left/Right Hemisphere
In left-handed people, the motor cortex in the right hemisphere is dominant for fine motor behaviors, such as writing with a pencil
Corpus Callosum
riding a bike
Occipital Lobes
Your occipital lobe recognizes writing, and then it works with a part of your brain’s temporal lobe to recognize the written shapes and symbols
Parietal Lobes
Knowing if something is on your left or right side
Temporal Lobes
when you see a cup and recognize it as a container to drink out of
Frontal Lobes
self-control and inhibitions, attention span and working memory
Somatosensory Cortex
when a person could hold a spoon with their eyes closed and be able to identify the object as a spoon based on its texture, temperature, and shape
Motor Cortex
one cell may fire strongly when the hand is moved to the left, whereas it will be inhibited when the hand is moved to the right
Broca’s Area
responsible for producing language
Wernicke’s Area
if a person were to say, “I love Study dot com because it helps me study,
Computed Tomography–CT
llow better imaging of the activity of neurotransmitter
Magnetic Resonance Imaging–MRI
to scan a person’s brain while they are performing a specific cognitive task,
Electroencephalogram–EEG
EEG may be used to monitor the depth of anesthesia during surgical procedures
Positron Emission Tomography–PET
study the brain activity of individuals with depression by injecting a radioactive tracer that binds to dopamine receptors
Functional MRI–fMR
some subjects demonstrate a failure to activate specific frontal regions during a verbal working memory task
Lesioning Studies
one patient could not form sentences after damaging a specific area of his brain
Electrical Stimulation of the Brain
speech arrest
