Effects Of Adolescent Alcohol Binge Drinking On Prefrontal Myelin, Wanette M. Vargas-Rodriguez
Effects Of Adolescent Alcohol Binge Drinking On Prefrontal Myelin, Wanette M. Vargas-Rodriguez
Doctoral Dissertations
Alcohol binge drinking is highly prevalent in teenagers and is associated with various harmful health effects and social problems. During adolescence, brain regions such as the prefrontal cortex (PFC) are still undergoing active development, characterized by increases in white matter volume. While the morphological details and the cellular and molecular sequences governing adolescent white matter development are not fully known, it is known that this development process is sensitive and can be disrupted. Although consumption of alcohol in a binge drinking pattern has been linked to lower white matter integrity in humans, it is important to determine if alcohol is …
Spider Brain Morphology & Behavior, Skye M. Long
Spider Brain Morphology & Behavior, Skye M. Long
Doctoral Dissertations
Spiders are ideal model animals for experimental and comparative studies of behavior, learning and perception. They display many complex behaviors, such as the multimodal mating dances of lycosid spiders, the stealthy hunting strategies of the jumping spider Portia sp., to the labile sociality of theridiids. Spiders also demonstrate a wide range of cognitive capabilities. Spiders perceive their environment using multiple sensory modalities including: chemosensory organs; lyriform and slit-sense organs and specialized hairs that detect vibration and air movement; and up to eight eyes that vary in function, some able to detect polarization and a broad spectrum of light, including …
