Preserved Consciousness In The Absence Of A Cerebral Cortex, The Legal And Ethical Implications Of Redefining Consciousness And Its Neural Correlates: A Case For A Subcortical System Generating Affective Consciousness, Shadia Kawkabani
Williams Honors College, Honors Research Projects
Historically, the scientific and medical communities have taken a corticocentric view on consciousness, emphasizing the need for a cortex in producing the conscious experience. The preserved consciousness observed in hydranencephalic children and decorticated rats suggests that some form of consciousness may be produced by a subcortical network. The brainstem, a phylogenetically ancient and conserved brain structure, could serve as the major integrative machinery to produce this form of consciousness, which is called affective consciousness—the evolutionary antecedent to the reflective consciousness that allows humans to reflect on their experiences. The functional convergence of the brainstem with the amygdala, motor system, and …

Quantifying Cortical And Cancellous Bone Volume: A Computed Tomography Approach, Hannah Rutkowski

Human identification primarily uses long bones of the body such as femora and tibiae which have a high cortical bone amount, these are thought to contain the highest amount of DNA. However, current research shows this is not the case, cancellous bone could contain more DNA in the porous spaces than dense cortical bone. This study aims to measure the variation in the amount of cortical and cancellous bone taken from sampling sites of seven individuals from ten different skeletal elements: femur, tibia, middle rib, calcaneus, first cuneiform, patella, third metacarpal, third metatarsal, first distal phalanx, and cervical vertebra. This …
