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