Question and answer
Q: What are the relationships of brain functions that are specific to literacy and learning?
A: As it turns out, the very act of study­ing and learn­ing can help to keep the brain healthy. [ There is then a unique and ben­e­fi­cial inter­play between study­ing sci­ence, improv­ing health, and improv­ing brain function. To under­stand this inter­re­la­tion­ship, con­sider what hap­pens when you learn some­thing new. Every men­tal activ­ity — includ­ing learn­ing — is played out as pre­cise
elec­tri­cal and chem­i­cal activ­ity in brain cells. The elec­tri­cal activ­ity spe­cific to study­ing and learn­ing directly causes the release of a mol­e­cule called brain derived neu­rotrophic fac­tor or BDNF. BDNF was first iden­ti­fied as a growth and devel­op­men­tal fac­tor in the brain, but now is known to be linked to improved learn­ing and mem­ory. When BDNF is increased through this pre­cise learn­ing related neural activ­ity, men­tal func­tion improves. When BDNF is exper­i­men­tally blocked, mem­ory for­ma­tion is made more dif­fi­cult. How does BDNF help to improve brain func­tion? It helps to phys­i­cally build and reshape parts of brain cells so that the cells can strengthen their con­nec­tions to each other. These spe­cific mod­i­fi­able con­nec­tions between brain cells account for our abil­ity to form and strengthen mem­o­ries. Many details in this model of brain train­ing need to be filled in, but clearly, con­crete mol­e­c­u­lar links have been iden­ti­fied to sug­gest that cer­tain kinds of men­tal activ­ity are nec­es­sar­ily linked to improved men­tal ability. ]
