Towards a neocortically-inspired ab initio cellular model of associative memory
… the real world. Such systems have a variety of sensory inputs that provide access to the richness, complexity, and noise of real-world signals. Specifically, the systems we design and implement are ab initio (simulated) spiking neural networks (SNNs) with cellular resolution and complex network …

Taking attention away from the auditory modality : investigations of the effect on speech processing using machine learning
… processing often takes place in complex multisensory environments. Listeners may need to prioritize sensory inputs from modalities other than audition. Selective attention is thought to be critical in selecting the sensory modality most relevant to the task at hand. Two critical research …

Characterizing Locust Anemotaxis: The Impact of Sensory Perturbations on Flight Behavior
<p>This thesis investigates the effects of sensory perturbations on locust flight behavior, with the goal of better understanding how locusts integrate multiple sensory inputs to maintain flight control. Through a series of experiments, locusts were subjected to visual impairment, turbulent wind …

Risk factors for Achilles tendinopathy in runners - an investigation of selected intrinsic, kinematic, kinetic and muscle activity factors that are associated with Achilles tendinopathy
… This study also aims to understand how different sensory inputs, such as shoe or pain may affect biomechanics. Thirty four uninjured runners (UN) and twenty one runners with Achilles tendinopathy (AT) composed the population sample for this study. Questionnaire and lower limb measurements were …

Generation and tuning of learned sensorimotor behavior by multiple neural circuit architectures
… have a remarkable ability to respond to complex sensory inputs with intricate, tuned motor patterns. How does the brain organize and tune these motor responses, and are certain circuit architectures, or connectivity patterns, optimally suited for certain sensorimotor applications? This thesis …

Effect of neck muscle vibration on upper limb sensorimotor integration and motor performance
… cerebellum is heavily involved in SMI of neck sensory inputs and motor learning; therefore, it is likely that altered neck sensory input will impact cerebellar processing. However, it is unclear whether acute models of altered afferent input from vibration impacts SMI, somatosensory processing, …

Autistic Traits and Cognitive Biases for Emotional Faces in Neurotypicals
… biases can involve the tendency to extract some sensory inputs while ignoring others. Cognitive biases impact perception, and subsequent processing decisions made on the basis of perception. Cognitive biases can disrupt accurate and efficient processing of social information, and may underlie …

Analyzing Multimodal Interactions through Improved Partial Information Decomposition Estimation
… models by integrating information from diverse sensory inputs such as text, audio, and vision. However, significant challenges remain in understanding how these different modalities interact and contribute to downstream tasks. In particular, we seek to characterize how modalities complement each …

Hmm-Based Semantic Learning for a Mobile Robot
… the underlying structure of continuous-valued inputs and representing that structure in the states of the model. These states can then be treated as symbolic representations of the inputs. We show how a model consisting of a cascade of HMMs can be embedded in a small mobile robot and used to …

Gelsight robotic fingertip
… This paper discusses the primitives and the sensory inputs they would require to create more precise manipulation models. We then propose a gelsight tactile sensor around those primitives, creating a design that can recover shear, deflection, compliance, and contact area information. Lastly, …

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 …

A Neuropsychological Investigation of Cerebral Dominance and Dyslexia
… measured with procedures designed to deliver sensory inputs to only one side of the brain initially. Visually, stimuli can be presented tachistoscopically to either the right or left visual hemifields, and tactually, stimuli can be presented to either the right or left hand. Since sensory …

Content representation in the human medial temporal lobe
The transformation of sensory inputs into complex memory representations is fundamental to human experience; yet, little is known about how this crucial process is achieved. When you meet your friend at the new cafe in town, what part of the brain encodes this novel scene into long term memory? …

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 …

Multisensory Integration in Early Toddlerhood: Interrelationships with Context, SES and Expressive Vocabulary
… environment, we receive information from various sensory inputs, and yet, we perceive and integrate the incoming information in a way that is meaningful. Remarkably, infants and toddlers are capable of sensory integration early in life. By integrating information, particularly speech, infants …

The role of renal afferent signalling in chronic intermittent hypoxia-induced sympathoexcitation and hypertension
Introduction: Sensory inputs from the kidney induce sympatho-excitation, and are integrated in brainstem regions receiving protective sensory inputs from high- and low-pressure baroreceptors. Blunted baroreflex control of renal sympathetic nerve activity (RSNA) was revealed in hypertension models …

Investigating Experience-Dependent Plasticity in the Accessory Olfactory Bulb
Chemosensory information processing in the mouse accessory olfactory system (AOS) guides the expression of social behavior. After salient chemosensory encounters, the accessory olfactory bulb (AOB) experiences changes in the balance of excitation and inhibition at reciprocal synapses between mitral …
