Psych 115 Exam Questions and Answers
100% Pass
This type of declarative memory stores information about events in the past.
What is episodic memory?
This technique to memorize long strings of information was used by Cicero, a lawyer from Ancient
Rome.
What is "Memory Castle"?
These kinds of memories are not dependent upon the hippocampus
What is nondeclarative/procedural memory (skill learning, priming, or conditioning)?
This kind of memory for facts and information is not tied to any specific time or place.
What is semantic memory?
Patient HM exhibited these two types of amnesia.
What is anterograde amnesia and temporally graded retrograde amnesia.
Lesions in the hippocampus do not impair remote memories, but do impair these kinds of memories.
What are recent memories?
Hippocampal lesions do not impair fear conditioning to auditory cues, but do impair this kind of
conditioning.
What is context conditioning?
This behavioral technique can be used to assess declarative memory in primates
What is the delayed non-match to sample (DNMS) task?
in the delayed non-match to sample (DNMS) task in primates, lesions in this brain region impairs long
delays.
What is the hippocampus?
In the delayed non-match to sample (DNMS) task in primates, lesions in this brain region impairs short
delays.
What is the prefrontal cortex?
The hippocampus is necessary for this kind of memory
What is declarative memory (episodic and semantic)?
This subregion of the hippocampus is involved in pattern completion.
What is the CA3 region?
This highly organized circuit is revealed by a transverse cross section of the hippocampus, composed
of three connections.
, What is the tri-synaptic loop?
This subregion of the hippocampus is involved in pattern separation.
What is the dentate gyrus?
These cells are one of the two neural populations in the mammalian brain that undergoes adult
neurogenesis.
What are dentate granule cells?
The opposite of long-term potentiation (LTP) reduces the size of the stimulus response.
What is long-term depression (LTD)?
This type of stimulus frequency results in long-term potentiation.
What is high-frequency stimulus (or HFS or 100 Hz)?
This type of receptor functions as a coincidence detector and is important for LTP.
What are NMDA receptors?
In LTP (Long-term Potentiation), this transcription factor activates the expression of genes which
results in proteins that build new dendritic spines.
What is CREB?
Much research on LTP/LTD has been based on this bundle of axons which connects hippocampus
region CA3 to CA1.
What are Schaefer collaterals?
Each place cell fires when the animal visits this preferred location.
What is the cell's place field?
When contextual cues rotate, place cell firing patterns re-orient themselves in this way.
What is place cell firing pattern rotation?
This kind of "heat map" has hot colors which indicate areas of high firing and cool colors which
indicate areas of low firing.
What is a firing rate map?
Border cells and grid cells are located in this brain region.
What is the entorhinal cortex?
When a place cell fires, it bursts rhythmically at this rhythm.
What is the theta rhythm (or 8 Hz)?
Rats with hippocampal lesions are impaired at this memory task.
What is the Morris Water Maze?
