Additional Psychology Flashcards

 


 

Cards

Term
what is psychology
Definition

Definition

-mental events can cause BOTH mental/physical events

-physical events can cause BOTH mental/physical events

Term
psychophysical parallelism
Definition

neuron
Definition
electrically excitable cell that processes and transmits information by electrical and chemical signaling
Term
3 functions of neuron
Definition

1 recieve inputs from senses and other neurons (dendrites and soma)

2 integrate this input (axon hillock)

3 generate an output (axon, synaptic terminals)

Term
resting potential
Definition
inside neuron is -70 mv w respect to outside 
Term
action potential
Definition

ALL OR NOTHIGN

charge = -55mv

inside goes from -70mv to +30mv and back

milisecond, have to wait to do it again

Term
synaptic potentials 
Definition
release chemicals to next cell (release signal, let diffuse)
Term
epsp (excitatory post-synaptic potentials)
Definition
takes neuron to threshold (-55mv)

ipsp (inhibitory post synaptic potentials)
Definition
takes neurons away from threshold (-55mv)
Term

produce myelin

phagocytes (cleans mess in body)

development (radial glial)

supportive matrix
