Answer
Question
cytoskeleton protein filaments   show
🗑
actin   show
🗑
G-actin (globular actin)   show
🗑
show 2-stranded helical polymer composed of globular actin  
🗑
show process of combining many monomers into a polymer  
🗑
show protein that depolymerizes F-actin  
🗑
show phosphorylation site of ADF/cofilin that regulates its ability to depolymerize F-actin  
🗑
LIMK1   show
🗑
show proteins located on the cell's surface that bind cells together  
🗑
show calcium-dependent cell adhesion molecules; strands of protein held together by Ca2+ ions; can exist as either monomers or cis-stranded dimers  
🗑
show theory that assumes that experience activates both the neurons that store the memory and other modulating neural-hormonal events that can influence the neurons that store the memory  
🗑
memory modulators   show
🗑
epinephrine (EPI, aka. adrenaline)   show
🗑
adrenoreceptors   show
🗑
norepinephrine (NE)   show
🗑
adrenergics   show
🗑
adrenergic receptors   show
🗑
propranolol   show
🗑
BLA (basolateral nucleus of the the amygdala)   show
🗑
show collection of neurons within the striatum that contribute to learning instrumental behaviors and may also modulate memory formation  
🗑
show frontal part of the cingulate cortex, believed to be involved in modulating memory formation  
🗑
vagus (aka vagal nerve or cranial nerve X)   show
🗑
show brain stem region that receives info from the vagal nerve  
🗑
show adrenal hormone that can modulate memory storage and is classified as a glucocorticoid  
🗑
glucocorticoid   show
🗑
RU 28362   show
🗑
clenbuterol   show
🗑
locus coeruleus   show
🗑
show syndrome in which individuals have unusually vivid recall of the traumatic events they experienced, accompanied by severe emotional responses  
🗑
secondary treatment   show
🗑
show brief crisis intervention usually administered within days of a traumatic event in which the trauma-exposed individual is encouraged to talk about his or her feelings and reactions to the event  
🗑
active trace theory   show
🗑
reconsolidation theory   show
🗑
show amnesia that is more pronounced for recently experienced events that for more remotely experienced events  
🗑
show theory that assumes that as episodic and semantic memories age they no longer require the medial temporal hippocampal system for retrieval  
🗑
show theory that assumes that a change in the strength of the memory trace is brought about by interactions b/t the MTH system and neocortex and which is assumed to take place over a long period of time, after the memory is initially established  
🗑
multiple trace theory   show
🗑
show method for imaging regional activity in the brain while the participant is engaged in cognitive activity  
🗑
show method for studying how rodents acquire food preferences from other rodents  
🗑
show system that is organized specifically to ensure that some particular need is met  
🗑
show innate behaviors that are supported by the fear system  
🗑
predatory imminence gradient   show
🗑
PAG (periaqueductal gray)   show
🗑
show region of the brain responsible for changes in the autonomic responses produced by the sympathetic nervous system that prepare an animal for action  
🗑
amygdala   show
🗑
CEc (lateral capsule)   show
🗑
show subnucelus of the CE of the amygdala thought to be an important part of the neural basis of fear; functions as the output region of the amygdala; when its neurons are activated, they in turn activate neurons in the PAG and LH that generate fear behaviors  
🗑
show pathway that carries info from the sensory thalamus to the lateral nucleus of the amygdala; thought to carry a somewhat impoverished representation of the sensory experience  
🗑
show pathway that carries info from the sensory thalamus to the neocortical regions of the brain where a richer, more detailed representation of the experience is constructed  
🗑
auditory cortex   show
🗑
show autonomic nervous system response related to the skin's ability to conduct electricity, used to measure defensive fear behavior  
🗑
show behaviors that can change or modify the environment and can be modified by the consequences that they produce  
🗑
show in a Pavlovian experiment, the elimination of a CR, achieved by presenting the CS w/o the US  
🗑
show hypothesis that assumes extinction is due to the CS-alone presentation eliminating the original CS-US association  
🗑
show hypothesis that assumes extinction produces a new association called a CS-noUS association, which the original CS-US association that produced the CR remains intact  
🗑
show recovery of an habituated response that occurs "spontaneously" with the passage of time  
🗑
show one of several ways to recover an extinguished CR, achieved by changing the context for extinction but later returning an animal to the training context to recover the CR  
🗑
show new association generated when the CS is no longer presented with the US; forms the basis of the competing memory theory in extinction studies  
🗑
intercalated neurons   show
🗑
show cortical region that is believed to suppress the action system and thus to play an important role in selecting which system--the action or habit system--controls instrumental behavior  
🗑
show drug that is a partial agonist and that binds to the glycine site of the NMDA receptor to enhance its opening  
🗑
exposure therapy   show
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
