How memories are formed and lost - Coggle Diagram
How memories are formed and lost
Neurons communication
dedicated sites called synapses
using specialized neurotransmitters
2 neurons communicate repeatedly
efficiency increase
called long term potentiation
memories stored long-term
Form
experience something. ex: Dialing a phone number
convert into a pulse of electrical energy
zip along network of neurons
short term memory in seconds-> minutes
long term memory through areas : hippocampus
storage regions across the brain
Lost
Age
older -> synapses begin to falter, weaken
affect to ability to retrieve memories
theory from scientist
brain shrinkage
hippocampus loses 5% neurons every decade
total: lost 20% by the age of 80 years old
drop in the production of neurotransmitters
ex: acetylcholine => affect to learning, memory
Mental, physical heath problem increase as age
interfere ability to pay attention
Chronic stress
constantly overloaded, personal responsibilities
the body in hyperalert
=> form Stress chemicals
mobilize energy
increase alertness
neg: body become flooded with chemicals
loss brain cells
inability to form new ones
affect to retain new information
Depression
40% develop memory problems
low level off serotonin
a neurotransmitter connected to arousal
result
less attentive to new information
dweling on sad events in the past
difficult to pay attention to the present
affect to store short-term memory
Solution
social interaction => give brain a mental workout
Physical active:
increase blood flow to the brain
eat well
keep the functioning correctly
give brain a workout
learn a new language
best defenses => keep memory intact
