Memory System Flashcards
What does your brain’s memory focus on?
Instead of unimportant factual memories, the memory focuses on important linked to strong emotions or things that come up regularly.
Where does the hippocampus receive information from?
From the brain’s primary sensory areas as well as neighboring areas like the rhinal and entorhinal cortices. Inputs also come from other areas like the amygdala, hypothalamus, and cingulate gyrus.
Where is information stored?
Memories are stored near places related to their context. Example: memory of a certain song will be stored close to the auditory cortex and memory of someone’s face will be stored close to the visual cortex.
Which part of the brain is crucial in storing memories?
Hippocampus.
What can damage to the hippocampus do?
This can prevent new long term memories from being formed but the old ones will stay because they’re generally not stored in the hippocampus.
Where does most of the input to the hippocampus come from?
The entorhinal cortex which has six layers and help process perceptual and sensory information before moving it along.
How many layers does the hippocampus have?
Three, making it a lot more simplistic but still as crucial.
What is short-term memory?
Short term memory is generally maintained in the prefrontal cortex in the top and side regions. The type of memory lets you retain information for a few minutes and doesn’t last long till you stop focusing on it.
What is long-term memory?
It is the result of three processes: encoding, storage, and recall. Encoding is learned and acquiring. Storage is storing the info away. Recall is the ability to remember the info.
What can long-term memory be divided into?
Explicit and Implicit memory.
What is explicit memory?
memory that can be consciously recalled. memory that is factual with no context or emotions (semantic memories). memory that is related to experiences or episodes (episodic memories) in your life. this memory must be consolidated by the hippocampus to be ready for long term storage.
What is implicit memory?
this is unconscious and unrehearsed memory. these types of memories or slower to encode but stick around for a lifetime.
What is a subtype of implicit memory?
Procedural memory, which is memory related to motor skills like riding a bike or playing an instrument. This involves motor regions of the brain like the cerebellum. Habits are also a subtype.
What else can implicit memories result from?
Priming - exposure to one stimulus affects and influences the memory.
What is Classical Conditioning?
This is getting one to form an association between something positive or negative (like candy or a shock) and something neutral (like a bench).
