How are memories recalled?
Context
Three types of memory according to retention duration
Immediate, working, and long-term memory
Type of memory according to retention duration that is just usually a snapshot or point in the environment. In milliseconds.
Immediate Memory
Type of memory according to retention duration where you remember an event and this include facts, observation, and information useful for a particular task. In minutes.
Working memory (Ang gina muno ni Doc Licup nga dapat ang mga basics mangin part don kadaya hay gamiton ta on a daily basis.)
Where does working memory get consolidated?
Hippocampus
The more emotionally uninvolved you are on a certain experience, the more you will recall it.
False (Must be more emotionally involved)
Type of memory according to retention duration that is the consolidation of working memory. Hours to many years.
Long-Term Memory
Which structures do storage of long-term memory depend on?
Prefrontal Cortex and Inferior Temporal Cortex
Two types of memory according to function
Declarative and Procedural
Type of memory according to function which is memory in words and is a conscious recall.
Declarative
Type of memory according to function which is memory in pictures, might be unconscious, preconscious, subconscious and is involved in skills and habits.
Procedural
Why is there infantile amnesia?
There is a lack of words to describe experiences during ≤2 y.o.
It is the link between emotion, stress, and memory.
Memory Modulation
It happens during recall and is the chance to change the memory everytime it is recalled.
Reconsolidation
Emotion or feeling is evoked to stimulate recall of memories long ‘forgotten’ by an individual.
Unconscious Recall
Primary neurotransmitter that helps store memories in a way that they are easy to remember.
Glutamate/Glutamic Acid
Neurotransmitter present during hyperarousal.
Glutamate/Glutamic Acid
Block the action of glutamate thus calms and makes an individual sleep
GABA
GABA receptor that works in tandem with glutamate receptors to balance the excitation of the brain in response to external events such as stress.
Synaptic GABA receptor
GABA receptor that is internally modulated and ignore glutamate. Involved in memory in dream states.
Extra-Synaptic GABA receptor
GABA receptor that changes the brain’s state to make us aroused, sleepy, alert, sedated, inebriated or even psychotic
Extra-Synaptic GABA receptor
GABA receptor that helps encode memories of fear-inducing event and stores them away from consciousness.
Extra-Synaptic GABA receptor
If a traumatic event occurs when extra-synaptic GABA receptors are activated, the memory of this event can be accessed unless these receptors are activated once again.
False (memory of event can’t be accessed)
Critical for retrieval of intermediate-term contextual and spatial memories but not necessary for retrieval of consolidation of memories in general.
Adrenergic signaling (Epinephrine and Norepinephrine)
Role of Norepinephrine in retrieval of memory requires signaling through which receptor in the hippocampus?
β1-adrenergic receptor
Disorder based on narrower trauma criteria that focus on acute life threatening situation, serious injury, or sexual violence by way of direct or indirect confrontation.
PTSD
It refers to a great misfortune causing great amount of material damage and human suffering and overwhelms the coping mechanism.
Disaster
Which is more traumatizing, natural vs. human caused?
Human caused
Which is more traumatizing, visible impact vs. low point (no physical evidence)?
Low point
Duration before post traumatic stress response is considered a disorder?
~ 8 weeks
Prevalence of PTSD on general population?
5 – 10%
It is a fight or flight or freeze response.
Trauma
Duration of acute stress syndrome.
3 days to 1 month
T or F: Younger age group is less prone to PTSD.
False (more prone)
In which level of the brain do differences in person’s responses to trauma could be seen?
Limbic System
T or F: Main problem in trauma is separating feelings from event or thought because it is difficult to deal with.
True
