Lactate is a carbohydrate breakdown product typically produced in astrocytes, a type of glial cell, and transported to neurons within the brain. This type of metabolic coupling is commonly referred to as the astrocyte neuron lactate shuttle (ANLS). While numerous studies have shown that the ANLS is involved in cognition in mammals few have taken into consideration sex differences, changes with age, or evolutionary conservation in invertebrates. Lactate metabolism is controlled by the enzymatic interconversion of pyruvate and lactate in a reaction catalyzed by lactate dehydrogenase (LDH). In this thesis I examined cognitive changes across lifespan affected by genetic manipulation …

Myeloarchitectonic Maps Of Cat Auditory Cortex, Austin Robertson
Electronic Thesis and Dissertation Repository
The cerebral cortex contains myriad cortical areas that differ in structure, function, and connectivity. Current methods of delineating cortical structures and their subregions are insufficient for in vivo applications, either being highly invasive or requiring a detailed knowledge of a region’s tuning properties. To address this, we seek to establish a structural biomarker capable of delineating the cortex that possesses a non-invasive correlate. We explore myelin as a potential candidate by evaluating its efficacy in parcellating the feline auditory cortex through the generation of depthwise myelin density profiles for each of the 13 auditory cortical subregions. Our analyses revealed significant …
In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber
In Search Of Psychiatric Kinds: Natural Kinds And Natural Classification In Psychiatry, Nicholas Slothouber
Electronic Thesis and Dissertation Repository
In recent years both philosophers and scientists have asked whether or not our current kinds of mental disorder—e.g., schizophrenia, depression, bipolar disorder—are natural kinds; and, moreover, whether or not the search for natural kinds of mental disorder is a realistic desideratum for psychiatry. In this dissertation I clarify the sense in which a kind can be said to be “natural” or “real” and argue that, despite a few notable exceptions, kinds of mental disorder cannot be considered natural kinds. Furthermore, I contend that psychopathological phenomena do not cluster together into kinds in the way that paradigmatic natural kinds (e.g., chemical …
