Objective: Combinations of various teaching strategies have been employed to enhance neuroanatomy teaching, to little success. Herein, we describe the use of integrated clinical scenarios in anatomy laboratory sessions as an educational strategy to improve the learning process for students undertaking neuroscience course. Methods: We assessed the perception and performance of students who utilised the integrated clinical resources in the neuroanatomy labs. We also compared the performance of the students on their neuroscience course with the performance of the previous year's students (who did not use the clinical scenarios). Results: A total of (130) 88% of the registered student both …
Physiological Effects Of Activity-Based Anorexia In Female Rats And An Overview Of Eating Disorders, Madelyn Uyemura
Physiological Effects Of Activity-Based Anorexia In Female Rats And An Overview Of Eating Disorders, Madelyn Uyemura
Regis University Student Publications (comprehensive collection)
The aim of this thesis is to bring AN to the foreground of conversation both in a scientific and sociological framework. Nearly 40 million Americans suffer from anxiety disorders, which is characterized by the feeling of a loss of control. In some cases, another disorder called anorexia nervosa (AN) can codevelop. AN is characterized by a refusal, and inability, to maintain a healthy body weight. Some suffering from anxiety may restrict caloric intake and increase exercise to cope with stress. This results in extreme caloric deprivation. AN can be modeled in rats using an activity-based anorexia (ABA) method. In …
Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar
Medical Schools Ignore The Nature Of Consciousness At Great Cost, Anoop Kumar
Journal of Wellness
The essential question of the relationship between consciousness and matter is ignored in medical school curricula, leading to a machine-like view of the human being that contributes to physician burnout and intellectual dissatisfaction. The evidence suggesting that the brain may not be the seat of consciousness is generally ignored to preserve the worldview of the primacy of matter. By investigating new frameworks detailing the nature of consciousness at different levels of hierarchy, we can bring intellectual rigor to a once opaque subject that supports a fundamental reality about our experience: We are human beings, not only human bodies.
Spinal Motor Neuron Excitability And Balance Control Changes Following Downslope Walking, Nikki Aitcheson-Huehn
Spinal Motor Neuron Excitability And Balance Control Changes Following Downslope Walking, Nikki Aitcheson-Huehn
Theses and Dissertations (Comprehensive)
Downslope walking (DSW) has been proposed as a rehabilitation tool for people with Multiple Sclerosis (PwMS) although there are mixed findings in young adults (YA) regarding the balance control changes, despite both populations experiencing depressed spinal motor neuron (MN) pool excitability. Our aim was to determine whether YAs could demonstrate improved balance control in conjunction with SOL H reflex depression (estimate of spinal MN excitability) following DSW. We also aimed to determine whether reciprocal inhibition was a potential mechanism for H reflex depression via conditioned SOL H reflexes. Thirty young adults (23±1.4y, 6 males) were assigned to 30-minutes of DSW …
Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal
Neuroanatomy Of The Blackspotted Rockskipper, Entomacrodus Striatus, Pooja Dayal
Williams Honors College, Honors Research Projects
Here I characterized the central neuroanatomy of the Blackspotted Rockskipper, Entomacrodus striatus, native to French Polynesia. The neuroanatomy of E. striatus has not been studied prior to this paper. I used several histology and antibody staining techniques to accomplish this, including Crystal Violet, immunohistochemistry, immunofluorescence, and Bielschowsky’s Silver Nitrate staining. This paper describes the most successful techniques used, identifies major structures in the species’ neuroanatomy, and also explains why studying E. striatus is important in the future of vertebrate research.
Melanopsin-Expressing Retinal Ganglion Cells In Control Vs. Glaucomatous Retinas, Edward Hamad
Melanopsin-Expressing Retinal Ganglion Cells In Control Vs. Glaucomatous Retinas, Edward Hamad
Williams Honors College, Honors Research Projects
Glaucoma is a common cause of vision loss worldwide and has a large scope of symptoms, ranging from pupillary reflex defects to sleep disorders. These issues can be explained partially by a recently found subtype of retinal ganglion cells that express melanopsin, denoted melanopsin-expressing retinal ganglion cells or mRGCs for short. These cells function primarily as photoreceptors in the non-image forming pathway, but can receive input from rods and cones. Since mRGCs play a role in the pupillary reflex and regulation of the sleep-wake cycle, I investigated if glaucoma leads to the degeneration of these cells in a mouse model …
Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre
Seeing Eye To Eye: A Machine Learning Approach To Automated Saccade Analysis, Maigh Attre
Honors Scholar Theses
Abnormal ocular motility is a common manifestation of many underlying pathologies particularly those that are neurological. Dynamics of saccades, when the eye rapidly changes its point of fixation, have been characterized for many neurological disorders including concussions, traumatic brain injuries (TBI), and Parkinson’s disease. However, widespread saccade analysis for diagnostic and research purposes requires the recognition of certain eye movement parameters. Key information such as velocity and duration must be determined from data based on a wide set of patients’ characteristics that may range in eye shapes and iris, hair and skin pigmentation [36]. Previous work on saccade analysis has …

Every year, millions of children undergo anesthesia for a multitude of procedures. However, studies in both animals and humans have called into question the safety of anesthesia in children, implicating anesthetics as potentially toxic to the brain in development. To date, no studies have successfully elucidated the mechanism(s) by which anesthesia may be neurotoxic. Animal studies allow investigation of such mechanisms, and neonatal piglets represent an excellent model to study these effects due to their striking developmental similarities to the human brain.
This protocol adapts the use of enzyme-based microelectrode array (MEA) technology as a novel way to study the …
Thalamocortical Processing Of Temporal Cues In Sounds, Kasey Smith
Thalamocortical Processing Of Temporal Cues In Sounds, Kasey Smith
Honors Scholar Theses
The ability of the brain to extract meaningful information from complex sounds is what allows mammals to understand species-specific communication as well as important environmental cues such as the sound of water or of potential predators or prey. The auditory cortex of humans and other mammals contains multiple cortical regions that unique sensitivities to both spectral and temporal sound cues. This discourse will explore three main factors proposed to determine these distinct processing capabilities in regard to temporal sound cues; the distribution of glutamate transporters in the thalamus, the architecture of afferent pathways between the thalamus and auditory cortex, and …

Habituation And Prepulse Inhibition Of The Acoustic Startle In Rodents, Bridget Valsamis, Susanne Schmid
Habituation And Prepulse Inhibition Of The Acoustic Startle In Rodents, Bridget Valsamis, Susanne Schmid
Anatomy and Cell Biology Publications
The acoustic startle response is a protective response, elicited by a sudden and intense acoustic stimulus. Facial and skeletal muscles are activated within a few milliseconds, leading to a whole body flinch in rodents. Although startle responses are reflexive responses that can be reliably elicited, they are not stereotypic. They can be modulated by emotions such as fear (fear potentiated startle) and joy (joy attenuated startle), by non-associative learning processes such as habituation and sensitization, and by other sensory stimuli through sensory gating processes (prepulse inhibition), turning startle responses into an excellent tool for assessing emotions, learning, and sensory gating. …

We present MINEMO (Minimal Information for Neural ElectroMagnetic Ontologies), a checklist for the description of event-related potentials (ERP) studies. MINEMO extends MINI (Minimal Information for Neuroscience Investigations)to the ERP domain. Checklist terms are explicated in NEMO, a formal ontology that is designed to support ERP data sharing and integration. MINEMO is also linked to an ERP database and web application (the NEMO portal). Users upload their data and enter MINEMO information through the portal. The database then stores these entries in RDF (Resource Description Framework), along with summary metrics, i.e., spatial and temporal metadata. Together these spatial, temporal, and functional …
