exercise
What is neuroscience?
the study of the brain
How does the speaker interact with the audience?
She makes them exercise for a minute.
Who gave the presentation?

How much exercise do you need to do to experience the benefits to your brain?
30 minutes 3-4 times a week
What type of scientist is the presenter?
neuro-scientist
What did the speaker study before looking into the effects of exercise?
Memory
While exercise doesn't cure the brain of disease like Alzheimer's and dementia, what can the extra volume in the brain do?
slow down the effects of the diseases
What were the two important areas of the brain discussed in the Ted Talk?
prefrontal cortex, temporal lobe (hippocampus)
Why did the presenter decide to change their research?
her personal experience
What benefits did the speaker find about exercise?
better mood, focus, energy
What functions does the prefrontal cortex help preform?
decision-making, focus, personality
What does the hippocampus do?
retain long-term memories/events
Long-term exercise can change the hippocampus by increasing the number of cells and volume of the brain. What benefits does this have?
Better long-term memory
How does the prefrontal cortex change from exercise?
better focus
How much time does research show that focus is improved after a single workout?
2 hours
What is one chemical in the brain released during exercise that improves mood?
dopamine, serotonin, nor-adrenaline
What example does the speaker give about what you can do with improved reaction time?
Catching Starbucks cups of coffee from falling
What does the presenter compare extra brain growth to?
