Schatner Terms Flashcards
retrograde/anterograde amnesia
retrograde- amnesia in which one is unable to retrieve old memories
anterograde- amnesia in which one is unable to form new memories
consolidation
is a category of processes that stabilize a memory trace after its initial acquisition.[1] Consolidation is distinguished into two specific processes, synaptic consolidation, which is synonymous with late-phase LTP[2] and occurs within the first few hours after learning, and systems consolidation, where hippocampus-dependent memories become independent of the hippocampus over a period of weeks to years. Recently, a third process has become the focus of research, reconsolidation, in which previously-consolidated memories can be made labile again through reactivation of the memory trace.
Korsakoff syndrome
amnesia produced as a result of long term alcoholism
limbic system
Combination of structures that include the hippocampus and the brain. The limbic system supports a variety of functions including adrenaline flow, emotion, behavior, motivation, long-term memory, and olfaction.[3] Emotional life is largely housed in the limbic system, and it has a great deal to do with the formation of memories.
caudate nucleus
The caudate nucleus is one of three basic structures that make up the basal ganglia. Along with the putamen and globus pallidus, as well in conjunction with the thalamus and two related structures the caudate nucleus constitutes a system that is responsible largely for voluntary movement.[1]
basal ganglia
a collection of structures that are critical for the execution of learned movements
evidence that 36 month old babies have preliminary episodic memory
infant is placed in a crib with a mobile that makes pleasant music when it kicks.
when the infant is placed back in the same environment it kicks again
children will demonstrate the same type of memory when looking for toys
perceptual representation system
a memory system whose purpose is to recognize items and terms, permitting rapid identification of formerly encountered stimulants.
unconscious plagiarism
occurs when a forgotten memory returns without it being recognized as such by the subject, who believes it is something new and original. It is a memory bias whereby a person may falsely recall generating a thought, an idea, a song, or a joke,[1] not deliberately engaging in plagiarism but rather experiencing a memory as if it were a new inspiration.
intrusive recollection
e first one is the most unique and is what sets PTSD apart from other anxiety disorders, and that is that the traumatic event has a life of its own. It continues to intrude. And we call these intrusive recollections, that someone is trying to listen to this interview, and they can’t because they can’t get it out of their mind what happened last night with an abusive partner or the traffic accident or the convoy that was attacked or what have you. These recollections are not invited; they’re not welcome guests, but they won’t go away, and you can’t not think about them.
weapon focus
during moments of high stress we may focus on items that can harm us or (help us harm others)
what is the result of electrical stimulation of amygdala
There are functional differences between the right and left amygdala. In one study, electrical stimulations of the right amygdala induced negative emotions, especially fear and sadness. In contrast, stimulation of the left amygdala was able to induce either pleasant (happiness) or unpleasant (fear, anxiety, sadness) emotions. Other evidence suggests that the left amygdala plays a role in the brain’s reward system.
psychogenic amnesia
is a memory disorder characterized by sudden retrograde autobiographical memory loss, said to occur for a period of time ranging from hours to years.
fugue state
a state in which a person is completely unaware of having lost all memory of who they are. They tend to focus on a set goal and only realized their state when they are told to identify themselves
dissociative disorder
previously known as multiple personality disorder (MPD),[1] is a mental disorder on the dissociative spectrum characterized by at least two distinct and relatively enduring identities or dissociated personality states that alternately control a person’s behavior, and is accompanied by memory impairment for important information not explained by ordinary forgetfulness.
