An Investigation Of The Role Of Amygdalar Circuits In The Production Of Social Behavior, Joseph Fd Dwyer
An Investigation Of The Role Of Amygdalar Circuits In The Production Of Social Behavior, Joseph Fd Dwyer
Doctoral Dissertations
Adaptive social behaviors allow animals to survive, thrive, and successfully reproduce. These behaviors, including mating, parenting, affiliation, and aggression, can be stereotyped in response to specific stimuli but often display sex-specific, and interoceptive-dependent variations in their execution. A conserved set of brain regions collectively known as the social behavior network (SBN) interprets sensory information about social cues and generates an appropriate behavioral response. In this dissertation I present 5 chapters. Chapter 1 introduces historical research focusing on the neural circuits that drive social behavior and the potential impact of environmental factors on the activity of these circuits. Chapter 2 describes …
The Consolidation Of Memory Associations, Kyle A. Kainec
The Consolidation Of Memory Associations, Kyle A. Kainec
Doctoral Dissertations
Creating memories is a fundamental challenge for the human brain. To create memories, defining features of experiences must be stored distinguishably without forgetting other memories. Memory associations represent co-occurring features and defining features across experiences. Memory associations are represented as networks of information that are stored in the brain. New memory associations are encoded during experiences and can be used to update existing memory associations during offline intervals. However, the mechanisms that underlie how encoded memory associations are stored within existing networks during offline intervals remains unclear. The experiments in this dissertation address a significant theoretical gap in understanding the …
Noradrenergic Regulation Of Decision-Making In Female And Male Rats, Emma S. Dauster
Noradrenergic Regulation Of Decision-Making In Female And Male Rats, Emma S. Dauster
Doctoral Dissertations
Decision-making is regulated by many associated brain regions, including the locus coeruleus (LC) and the prefrontal cortex (PFC). Disruptions in decision-making are a key feature of many disorders including attention-deficit/hyperactivity disorder which is disproportionately diagnosed in one sex over another for reasons unknown. LC or its primary neurotransmitter norepinephrine (NE) have been implicated in the etiology or treatment of disrupted decision-making. Understanding the relationship among LC, PFC, and decision-making across sexes may provide insight into the basic neurobiology of cognition and disorders that lead to disrupted decision making. There are sex differences in LC anatomy, however studies investigating sex differences …
