What kind of plasticity did Sajal overlook in his statement? . mental exercise promotes in the most involved areas a greater development of the protoplasmic extensions fle, dendrites] and faxon) collaterals As a result, associations that have alreody been created between certain celf groups strengthen themselves notably by multiplying the terminal twigs of the protopiasmic extensions fie, dendrites] and faxon] collaterols. In addttion, entirely new intercellular connections may establish themselves thanics to the formation of new collaterols and the expansion of Idendrites!" Ramon y Calal 1894 9. How would you expect the neocortex of professional baseball players to differ from that of people who have never played basebal?

Hebbian plasticity phenomenon work on synaptic connection selectively. Where as synaptic scaling works with other homeostatic neurons. This is how synaptic scaling is anti Hebbian
