exercise Flashcards
What are three things that rodent models show that aerobic exercise does to them?
- supports hippocampal neurogenesis and behavioral memory performance
- also supports new blood vessels and synpases in the entire brain
- decreases in brain inflammation
What is the modulating factor leading to increase in neurogenesis in dentate gyrus?
exercise
T or f: significantly less neurons are born as a result of aerobics
false, there are more neurons
What were the findings in exercise, hippocampus & memory in OLDER ADULTS?
- participants who engaged in aerobic exercise saw increases in hippocampal volume
- increases in volume were correlated with increases in memory performance
- increases in volume correlated with increased fitness level
What were the results in exercise, hippocampus, and memory in CHILDREN?
- higher-fit children had large hippocampi
- hippocampal volume correlated with relational memory performance
- ## hippocampal volume was not correlated with item memory
What was found about YOUNG ADULTS and their exercise, hippocampus & memory?
- aerobic fitness level correlated with hippocampal viscoelastic measure of tissue
- hippocampal viscoelasticity correlated with relational memory performance
What is the term for the non-invasive shear wave imaging technique for probing mechanical properties of biological tissues?
MRE
What was true about dietary intake and children?
- better dietary intake resulted in better relational memory for 7-9 yr olds
What are carotenoids?
- pigments producing the bright yellow, red, and orange color in food
What is a type of carotenoids?
lutein
What is the primary carotenoid in developing the hippocampus?
- lutein
What was the result in the macular carotenoids, health, and relational memory study?
- higher aerobic fitness, lower body fat, and higher lutein results in fewer swap errors aka better relational memory
Who was AJ?
- she has really good memory and remembers when she was a newborn
- she also organizes her memories due to a tramautizing move
- also keeps diaries from everything she experiences
What is the name of the syndrome AJ has?
- hyperthymestic syndrome
What is synesthesia?
a neurological condition in which stimulation of one sensory or cognitive pathway leads to involuntary experiences in another
What is the patients name that has synesthesia and can recall very detailed memories?
S
What is a memory palace/ method of Loci?
mnemonic device or technique used to improve memory by associating information with specific physical locations or “places” that are familiar to you.
What are super-recognizers?
- individuals who are exceptionally good at recognizing faces?
