Influence of Physical Environment and Sensory Stimuli on Behavior of Neonatal Pigs
… of piglets is affected by both physical and sensory factors.

Affordances In The Design Of Virtual Environments
… realized in the natural world and how lack of sensory stimuli may lead to realization failures in virtual environments. Implications of the model were empirically investigated by examining three affordances: passability, catchability, and flyability. The experimental design involved four …

THE INFLUENCE OF GAME DESIGN ON THE COLLABORATIVE PROBLEM SOLVING PROCESS: A CROSS-CASE STUDY OF MULTI-PLAYER COLLABORATIVE GAMEPLAY ANALYSIS
… games. The following game design attributes: sensory stimuli elements, level of challenge, and presentation of game goals and rules were examined to determine their influence on game player's collaboration and joint problem solving processes. Six participants were placed into four …

Relations between sensory-related factors and stress in autistic and non-autistic adults
… indicating that differences in self-reported sensory processing may be associated with differences in levels of stress in adult populations. Parenting often comes with increased sensory stimulation, such as noise or tactile stimulation. Therefore, responsivity to sensory stimuli could be a …

Categories of Mystical Experience in The Voice of the Silence by Helena Petrovna Blavatsky.
… passivity, transiency, indifference to sensory stimuli, and belief. These categories were compared and contrasted with James' four marks of religious experience. This analysis led to the discovery of two new categories, indifference to sensory stimuli and belief, which contribute to our …

Yin and Yang: Qualitative and Quantitative Research Investigating Physical and Psychological Effects Following a 6-Month Taiji (T'ai Chi) and Qigong (Ch'i Kung) Intervention With Older Adults
… in situations of inaccurate or conflicting sensory stimuli. Taiji practitioners also adopted significantly wider stance widths than their control group counterparts. The adoption of a wider stance may be one mechanism contributing to the observed improvements in functional balance.

Descending Control of Limb Movements in Drosophila melanogaster
… control on limb movements in a context where sensory feedback can be is reduced while leaving the nervous system, musculature, and cuticle of the animal relatively intact. Lastly we use in-vivo whole cell patch clamp electrophysiology to characterize the role of individual DNs in response to …

Interactions between the auditory and vibrotactile senses : a study of perceptual effects
… interactions between auditory and tactile stimuli. These experiments present vibrotactile stimuli to the fingertip and auditory tones diotically in broadband noise. Our hypothesis states that if the auditory and tactile systems integrate, the performance of the two sensory stimuli presented …

Impact of Brain State On Visual and Prefrontal Population Coding In Behaving Animals
… regarding how the brain processes incoming sensory stimuli. However, the interaction between behavioral activity and brain states throughout the cortical hierarchy of primates has not been understood. In particular, technical considerations have greatly limited the range of physical …

EFFECTS OF CHARACTER VOICE-OVER ON PLAYERS' ENGAGEMENT IN A DIGITAL ROLE-PLAYING GAME ENVIRONMENT
… 2002). Furthermore, despite the possibility that sensory stimuli can be factors influencing digital game players' engagement, there have been very few attempts to examine empirically the relationship between engagement and sensory stimuli. This study examined the effects of game characters' …

EXPERIENCE-DEPENDENT STRUCTURAL PLASTICITY IN A NATURALLY BEHAVING ANIMAL MODEL
… in future behavior via altered processing of sensory stimuli. The following chapters of this dissertation are aimed at identifying signaling pathways that control structural plasticity in the Kenyon cells of the worker honey bee brain correlated with foraging experience and identify how those …

Mechanisms of Specificity in Neuronal Activity-regulated Gene Transcription
<p>The ability to convert sensory stimuli into long-lasting changes in brain function is essential for animals to interact with and learn from their environment. This process is achieved by encoding sensory stimuli into temporal patterns of neuronal activity, which in turn modulate the connectivity …

Eisenia hortensis Detects Chemesthetic Irritants through TRP Channels
… used to image live cells in response to specific sensory stimuli. From our results, we conclude that E. hortensis possess TRPA1-like and TRPM8-like channels while lacking functional TRPV1 channels.

Multiple spatial memories in the brain : decoding and modification using microstimulation
Sequential processing --- using multiple sensory stimuli to plan and control a set of ordered movements --- is a central aspect of human behavior. Because previous and future movements must be stored during the execution of any movement in a sequence, memory is an indispensable aspect of sequential …

In Vitro, In Vivo, and In Silico Studies of Reticulospinal Circuits and Generalized Arousal
… a.) locomotor output, b.) responsiveness to sensory stimuli, and c.) emotional reactivity. Previous studies have identified the nucleus gigantocellularis (NGC), a small group of large-bodied neurons in the hindbrain reticular formation, as a potential neuronal substrate for GA. These neurons …

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 …

Touching Autism Spectrum Disorder: Somatosensory Abnormalities in Shank3b and Cntnap2 Mouse Models
… Today, several studies show that disturbances in sensory processing are a crucial feature of autism. Indeed, around 90% of individuals diagnosed with autism show atypical responses to various sensory stimuli. These sensory abnormalities (described as hyper- or hypo-reactivity to sensory …

The Dissociation of Sensory Integration and Associative Learning in Caenorhabditis elegans and the Molecular Mechanisms Leading to Memory Acquisition
… tyrosine kinase. scd-2 plays role in both sensory integration and associative learning, and was used to dissociate these two processes at the genetic, cellular, and behavioural levels. At the genetic level, it interacts differently with fsn-1, which expresses part of a ubiquitination …

Adenosine Production Is Essential for Closing the Critical Period of Cortical Plasticity
<p>Sensory inputs from the external world are represented as highly organized systems in the adult brain for effective adaptation to the environment. At the cortical level, this organization is referred to as cortical maps. The establishment of cortical maps begins with early life experiences …

Striatal Control of Sensory-Driven Behavior and Its Relevance for Neuropsychiatric Disorders
… how the tail of the striatum (TS), a major sensory hub within the basal ganglia, regulates actions in response to sensory stimuli. Mice performed an auditory Go/NoGo task while we recorded cell-specific activity from TS neurons to identify how distinct striatal pathways contribute to …
