Q

why does correlation not equal causation

A
  • correlation tells us how variables are related and the degree/strength of that relationship
  • not manipulating variables
  • extrenous variables

Q

Expain the process of how a neuron passes info to another neuron

A

Neurons communicate using electrical impulses. There is a gap called the presynaptic, sending neuron, and the postsynaptic, receiving neuron. the axon in the presynaptic neuron sends signals to the neurotransmitters which decide if they should fire or not. these neurotransmitters can bind to receptor sites on dendrites. if the neurotransmitter is unable to bind to the specific shape or there are already too many known neurotransmitters the presynaptic takes back the neuron through reuptake

transferring the sensation into a neural impulse
