Using sensory cues to curate, study and support autobiographical remembering across the lifespan
… with experimenter-provided stimuli as memory cues. Self-selected stimuli produced more specific memories overall and once again, the different stimuli evoked memories that reflected distinctive lifespan retrieval curves. Given that the musical reminiscence bump remained reliable in all …

Neural Sequences Underlying Directed Turning in C. elegans
… organization of the circuits that integrate sensory signals to select and execute appropriate motor sequences is not well understood. Here, we characterize the architecture of neural circuits that control C. elegans olfactory navigation. We identify error-correcting turns during navigation …

UNDERSTANDING THE PROCESS OF MULTISENSORY INTEGRATION
Multisensory integration, the process by which the brain integrates inputs from different senses, has enormous survival value, and the search for its guiding principles has yielded substantial insight into this remarkable process. At the single neuron level, responses are more robust to …

The ethology of the Malayan false vampire bat (Megaderma spasma), with special emphasis on auditory cues used in foraging
… impose different restrictions on the use of sensory cues by hunting bats, a primary focus of my work was to determine what cues are used by foraging M. spasma, and their role in generating adaptive behavioral responses.

A Scent of Direction: Exploring Adaptive Olfactory Navigation in Drosophila
<p>Animals rely on environmental cues, such as odors, to navigate through complex and often dynamic landscapes. While olfactory navigation has traditionally been modeled as a reflexive behavior driven by immediate sensory cues, whether flies can leverage more sophisticated strategies, integrating …

Generative AI for Human-Centric Design in Extended Reality Applications
… in XR, providing insight into how immersion and sensory cues affect human experience beyond self-report. Finally, a generative framework using variational autoencoders and latent diffusion is proposed for generating anthropometrically plausible yet diverse 3D human body models, also referred to …

Do Olfactory Stimuli Increase Presence During Exposure Tasks: A Comparative Study
… the exposure therapy process by presenting multi-sensory cues (e.g., sights, smells, sounds) to increase the patient*s sense of presence. While studies have shown that scents can elicit emotionally charged memories, no prior research could be identified that examined the effect of olfactory …

Dopamine and the Temporal Dependence of Learning and Memory
… or painful shock, impart meaningful valence onto sensory cues in the animal's environment. The ability of animals to form associations between a sensory cue and a rewarding or punishing reinforcement permits them to adapt their future behavior to maximize reward and minimize punishments. Animals …

Modulation and modeling of anticipatory postural adjustments for gait initiation in persons with Parkinson's disease
… and slower, less-coordinated gait initiation. Sensory cues have been demonstrated to improve gait initiation behaviors, possibly because they provide relevant information for movement to the motor cortex through cerebellar-thalamo-parietal pathways that remain intact during the disease process. …

The Role of Sensing Modalities in Shaping Collective Motion and Group Behavior
… environments. We explore how combining these sensory cues in a three-dimensional space affects the way groups move and behave. Our findings reveal that integrating auditory and visual information allows for more effective group coordination, combining the strengths of both senses. We also look …

Classification of Human Postural and Gestural Movements Using Center of Pressure Parameters Derived From Force Platforms
… Subtle body movements that can be caused by sensory cues such as visual or auditory, affective, cognitive, pathological or many other factors besides intended movements can be easily captured in the sway patterns derived from ground reaction forces and the body's center of pressure (COP). The …

Microfluidics for Calcium Imaging of C.elegans Neurons During Temporally Precise Odor Stimulation
How neurons process sensory stimuli to give rise to different behaviors is one of the most pursued and complex questions in neuroscience. With recent technologies, scientists have been able to map how sensory cues, like odors, are represented in the brain. However, it has been proven difficult to …

The Effects of System Reliability and Task Uncertainty on Unmanned Aerial Vehicle Operator Performance under High Time Pressure
… pilot. An UAS operator does not get the same sensory cues as a pilot and their field of vision is significantly restricted among other limitations.</p> <p>This study examined the effects of system reliability and task uncertainty on UAS operator performance, measuring image processing accuracy …

Use of magnetic and olfactory cues for orientation by a fossorial rodent, Thomomys talpoides
… of movement and reduced, or altered, sensory cues. I examined the ability of the North American pocket gopher, Thomomys talpoides, to use magnetoreception and olfaction in navigation and foraging. Magnetoreception was tested using three manipulative experiments: 1) field homing of …

Mnemonic information in the rodent hippocampus during wake and sleep states
… traces in the absence of active behavior or sensory cues, specifically during offline-periods such as sleep. While experience-dependent reactivation occurs during slow-wave sleep, there is no evidence for such activity during REM sleep, despite its association with human dreaming and putative …

Motion perception with conflicting or congruent visual and vestibular cues
… conflicting or ambiguous, information from both sensory sources (e.g. vestibular organs, visual, proprioceptive), and non-sensory sources (e.g. efferent copy, cognition)). This "spatial orientation" is normally subconscious, and information from multiple sense organs is automatically fused into …

Abdominal-B Neurons Control Drosophila Virgin Female Receptivity
… dimorphic courtship behaviors, a suite of sensory back-and-forth that offers an excellent model for studying the neural circuitry of complex behavior (Dickson, 2008). However, the study of Drosophila courtship has focused overwhelmingly on the male, and little is known about how the female …

Sensory Aspects of Foraging Behavior in the Least Weasel (Mustela Nivalis) (Prey Detection, Carnivora)
… behavior from the perspective of the predator's sensory abilities. Five least weasels were filmed while foraging within a 2.4 x 2.4 m grassland of durum wheat. Trials were filmed under daylight conditions and during manipulations designed to disrupt the weasels' perception of acoustic and visual …

Response to visual threats in Aedes aegypti mosquitoes
… as evade them. In order to do this, they rely on sensory cues that they must be able to continuously re-evaluate during host tracking to potentially decide to quickly escape at any point during these interactions. Host seeking is mediated by multiple sensory modalities such as vision, olfaction, …

Sensory and Neuromodulatory Entrainment of Foraging States in C. Elegans
