Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron Jul 2016

Insects Have The Capacity For Subjective Experience, Colin Klein, Andrew B. Barron

Animal Sentience

To what degree are non-human animals conscious? We propose that the most meaningful way to approach this question is from the perspective of functional neurobiology. Here we focus on subjective experience, which is a basic awareness of the world without further reflection on that awareness. This is considered the most basic form of consciousness. Tellingly, this capacity is supported by the integrated midbrain and basal ganglia structures, which are among the oldest and most highly conserved brain systems in vertebrates. A reasonable inference is that the capacity for subjective experience is both widespread and evolutionarily old within the vertebrate lineage. …


Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown Jan 2016

Comparative Evolutionary Approach To Pain Perception In Fishes, Culum Brown

Animal Sentience

Arguments against the fact that fish feel pain repeatedly appear even in the face of growing evidence that they do. The standards used to judge pain perception keep moving as the hurdles are repeatedly cleared by novel research findings. There is undoubtedly a vested commercial interest in proving that fish do not feel pain, so the topic has a half-life well past its due date. Key (2016) reiterates previous perspectives on this topic characterised by a black-or-white view that is based on the proposed role of the human cortex in pain perception. I argue that this is incongruent with our …


The Effect Of Visual Wulst Lesions And Trigeminal Nerve Sectioning On The Discrimination Of Magnetic Inclination In The Homing Pigeon (Columba Livia), Merissa Acerbi Jan 2013

The Effect Of Visual Wulst Lesions And Trigeminal Nerve Sectioning On The Discrimination Of Magnetic Inclination In The Homing Pigeon (Columba Livia), Merissa Acerbi

Honors Projects

The ability of homing pigeons to return to their loft from unknown places has fascinated scientists for centuries. It is well established that homing pigeons, like migratory birds, posses an innate magnetic inclination compass to determine direction by measuring the angle between the magnetic field vector and the Earth's surface. Recent work has indicated that the avian magnetic compass is light mediated and appears to mediate magnetic information to the brain. This occurs via a visual pathway with processing in the visual Wulst area of the forebrain. There is, however, also evidence from other avian species that magnetic direction may …


Cortical Representation Of Lateralized Grasping In Chimpanzees (Pan Troglodytes): A Combined Mri And Pet Study, William D. Hopkins, Jared P. Taglialatela, Jamie L. Russell, Talia M. Nir, Jennifer Schaeffer Oct 2010

Cortical Representation Of Lateralized Grasping In Chimpanzees (Pan Troglodytes): A Combined Mri And Pet Study, William D. Hopkins, Jared P. Taglialatela, Jamie L. Russell, Talia M. Nir, Jennifer Schaeffer

Functional imaging studies in humans have localized the motor-hand region to a neuroanatomical landmark call the KNOB within the precentral gyrus. It has also been reported that the KNOB is larger in the hemisphere contralateral to an individual's preferred hand, and therefore may represent the neural substrate for handedness. The KNOB has also been neuronatomically described in chimpanzees and other great apes and is similarly associated with handedness. However, whether the chimpanzee KNOB represents the hand region is unclear from the extant literature. Here, we used PET to quantify neural metabolic activity in chimpanzees when engaged in unilateral reach-and-grasping responses …


Winter Behavior Of Big Brown Bats (Eptesicus Fuscus) In A Building Roost: Intermittent Feeding, Passive Rewarming, And Energy Conservation, Amy L. Fairbairn Dec 2006

Winter Behavior Of Big Brown Bats (Eptesicus Fuscus) In A Building Roost: Intermittent Feeding, Passive Rewarming, And Energy Conservation, Amy L. Fairbairn

All-Inclusive List of Electronic Theses and Dissertations

I investigated the use of torpor and arousals during winter of 2005 - 2006 by freeliving big brown bats (Eptesicus fuscus) by measuring skin temperature (remotely using data loggers) and used those measurements to estimate winter energy expenditure. Torpor bouts lasted for a mean of 3 .3 days ( d) with a mean of 3 .6 d and 2.2 d for males and females, respectively. There was no correlation between ambient temperature (Ta) during torpor and torpor bout length, but there was a significant correlation between Ta and length of the active period. Arousals lasted on average 5.0 hours (h). …


The Role Of Facial Pits In The Thermoregulatory Behavior Of Pitvipers (Viperidae: Crotalinae) Behavioral, Ecological And Phylogenetic Perspectives, Aaron R. Krochmal Dec 2003

The Role Of Facial Pits In The Thermoregulatory Behavior Of Pitvipers (Viperidae: Crotalinae) Behavioral, Ecological And Phylogenetic Perspectives, Aaron R. Krochmal

All-Inclusive List of Electronic Theses and Dissertations

Pitvipers (Viperidae: Crotalinae) possess unique sensory organs, the facial pits, capable of sensing subtle fluctuations in thermal radiation. Prey acquisition has long been regarded as the sole function of the facial pits. However, the ability to sense thermal radiation could also direct thermoregulatory behavior by remotely sensing nearby surface temperatures. Using a series ofbehavioral arenas of varying spatial complexity and ecological relevance, I surveyed the ability of western diamondback rattlesnakes (Crotalus atrox) to direct successful thermoregulatory movements with either functional or disabled facial pits. I found that western diamondback rattlesnakes could base thermoregulatory decisions on thermal radiation cues when their …
