对于信息传播概念的旧理解 -> 新理解(补充) -> 新旧理解结合去解释一个概念, 说明信息传播比想象中要复杂
Neural information processing
Traditional view: synaptic transmission
- like electrons travel through conduits of circuits
- follow specific routes
- more rapid form (+)
- emit chemical signals into the extracellular fluid (-)
New concept: volume transmission (complements, rather than contradicts, synaptic transmission )
- signal through cerebrospinal fluid
- similar to radio broadcast
- more protracted timescales
- regulates brain’s reaction to synaptic activity (+)
RC Answers: EEABB
Premise: physical activities corr. with longevity;
Counter: physical activities (could be fake cause) -> social activities (real cause) -> longevity
Q: evaluate whether physical activities alone -> longevity
Gap: eliminate the middle cause. Directly compare physical activities's corr with longevity
