Your answer
How did motor learning experience impact spine formation?
*
Spine formation increased
Spine formation decreased
Spine formation stayed the same
How did trimming whiskers impact spine formation in enhanced environment?
*
Spine formation rate was roughly same as without whiskers trimmed
Spine formation rate was roughly same as it was in standard environment
Spine formation rate was more than it was without whiskers trimmed
Which of the statements are true?
*
Spines not eliminated were strongly correlated with learned motor performance
90% of early formed spines persist over an animals life
After fast spine formation early in life there is also net loss of spines after for some period
New experience leads to increased elimination of existing spines
Required
What are the two populations of stably maintained spines that were distinguished?
*
New spines formed early during development
Spines maintained throughout life
Spines maintained only for several months
