Electromagnetic Differences In The Brain During Memory Retrieval, Warren Scott Merrifield
Electromagnetic Differences In The Brain During Memory Retrieval, Warren Scott Merrifield
Loma Linda University Electronic Theses, Dissertations & Projects
The primary objectives for this experiment were to analyze the neuroanatomical correlates of autobiographical, episodic and semantic memory, use a different paradigm to promote episodic memory retrieval, and employ a different analysis technique to understand retrieval processes. Autobiographical and episodic memories are personal memories from the past. Autobiographical is more general (e.g. a street name of a house growing up) and episodic is more specific to time (e.g. 13th birthday party that took place on a street). For autobiographical and episodic memory retrieval operations, there is no general consensus as to the localization of function, but bilateral activation of the …

In week-old rats, lesions of the dorsolateral pontine tegmentum (DLPT) and nucleus pontis oralis (PnO) have opposing effects on nuchal muscle tone. Specifically, pups with DLPT lesions exhibit prolonged bouts of nuchal muscle atonia (indicative of sleep) and pups with PnO lesions exhibit prolonged bouts of high nuchal muscle tone (indicative of wakefulness). Here we test the hypothesis that nuchal muscle tone is modulated, at least in part, by cholinergically mediated interactions between these two regions. First, in unanesthetized pups, we found that chemical infusion of the cholinergic agonist carbachol (22 mM, 0.1 µL) within the DLPT produced high muscle …
Application Of Microsatellite Dna Markers To Discriminate Maternal And Genetic Effects On Scalation And Behavior In Multiply-Sired Garter Snake Litters, Gordon Burghardt
Application Of Microsatellite Dna Markers To Discriminate Maternal And Genetic Effects On Scalation And Behavior In Multiply-Sired Garter Snake Litters, Gordon Burghardt
Gordon Burghardt
Incomplete knowledge of pedigrees sometimes limits the methods of estimating quantitative genetic parameters (heritability, genetic correlation) in nature and may result in estimates that are inflated by nongenetic sources of variation. North American garter snakes and their allies provide a model system for investigating evolutionary quantitative genetics, but estimates of quantitative genetic parameters in these snakes are mostly based on offspring-dam regression and full-sib analysis, methods that fail to discriminate between maternal genetic, maternal environmental, and direct genetic effects on traits of interest. Using data from the garter snake Thamnophis sirtalis, we demonstrate that microsatellite DNA markers can be used …

Observations Of Rough-Toothed Dolphins (Steno Bredanensis) Off The Coast Of Utila, Honduras, Stan A. Kuczaj Ii, Deirdre Yeater
Observations Of Rough-Toothed Dolphins (Steno Bredanensis) Off The Coast Of Utila, Honduras, Stan A. Kuczaj Ii, Deirdre Yeater
Psychology Faculty Publications
Local dive shop operators and fishermen report that rough-toothed dolphins (Steno bredanensis) are frequently encountered off the coast of Utila, Honduras, (16°05'46.5"N 86°55'47.8"W). Our observations suggest that at least some of these animals may constitute a resident population, although the extent of the resident group’s home range has not been determined. Twenty-eight rough-toothed dolphins were identified using photoidentification techniques, 15 of which were re-sighted on two or more occasions. The 12 animals that were re-sighted four or more times were typically seen together, suggesting that they constitute a stable social group. At least one of these dolphins is …
