Innate Immunity and Thalamic Dysfunction in Autism

Sensory processing defects are a prominent feature of autism with descriptions of an over-reaction to noise, light, and touch and increased pain thresholds. The thalamus is the gateway of these sensory signals and recent reports indicate a marked suppression of thalamic metabolic activity in autistic children. Other studies reported excessive brain growth during the early life. The cause of these functional and structural brain abnormalities and resulting behavioral impairments remain unknown. A clue may be the recent finding of inflammation-activated glia in most autism brains. The inflammation was composed of glial cell growth and peptide secretion. Neurons perform the signal transmission and computations unique to the brain, while glial cells support these neuron functions. Resting glia provide structural and metabolic support to neurons improving their signaling properties. The effect of inflammation-activated glia on neurons is largely unknown. This project seeks answers to this question to understand what influence the inflammation-activated glia found in autism might have on the brain of individuals suffering from autism.

Career Development Award for Lindsay Oberman

This grant provides support for Dr. Lindsay Oberman in a translational research project that will extend and bridge two independent lines of research, both previously funded by the NLMFF. Specifically, with funding from NLMFF as well as NIH and Harvard Catalyst, Dr. Alvaro Pascual-Leone and Dr. Oberman have developed methods to noninvasively measure experience-dependent cortical plasticity both in healthy controls and patients with idiopathic ASD and Fragile X syndrome. Using noninvasive repetitive transcranial magnetic stimulation (rTMS), Drs. Oberman and Pascual-Leone have shown that patients with idiopathic ASD show an exaggerated LTD-like suppression of cortical excitability following a short train of rTMS while those with Fragile X (without ASD) syndrome show a complete lack of LTD-like suppression in response to the same rTMS protocol.

Under a separate line of research, also previously funded by the NLMFF, Dr. Matthew Anderson developed a mouse model of ASD based on triplication of the UBE3a gene (the genetic mutation that causes idic15 in humans) that reconstitutes correlates of the three core behavioral deficits that define ASD. Furthermore, they have developed a model mechanism where they propose that social deficits in individuals with idic15 may be a consequence of excessive experience-dependent social homeostasis.

Independently, these two lines of research have both contributed to our understanding of the underlying pathophysiology of the behavioral deficits that characterize ASD. A complete understanding, however, requires the direct translation of insights that we gain from basic science to applications that have direct impact for patients with the disorder. With this focus, this project aims to create a multi-disciplinary collaboration between the Anderson and Pascual-Leone lab with Dr. Oberman as the catalyst of this translational bridge. Thus, the aim is to develop novel assays, based on the previous work in the Anderson and Pascual-Leone lab, to evaluate neurological and behavioral phenotypes in human patients with a specific syndromic form of ASD, idic15.

Integration of iPads and Other AAC to Improve Communication for Individuals with Autism

Dr. Ashby’s research team aims to understand the potential of the iPad and other mobile technologies in supporting communication and inclusion of individuals with autism. What applications are most useful for individuals who do not speak or whose speech is highly limited? How can the iPad help individuals with autism develop greater independence, improve their motor planning, or develop verbal speech? Also, while the iPad has nearly unlimited potential, Dr. Ashby’s research team also wants to understand how it can be meaningfully integrated in school and community settings along with other communication strategies to increase meaningful access to academic, work, and social experiences. Technology alone is not sufficient; training and ongoing support is necessary to ensure that use of the technology enhances communicative interactions and educational access. Many schools and agencies are purchasing iPads with no plan for meaningful integration and no plan for how this new technology fits into a larger total communication approach.

The goal of this project is to enhance our understanding of the potential for iPads and other mobile AAC devices to support communication. Through this grant, Dr. Ashby’s research team will explore, evaluate, and organize applications that are most useful in helping non-speaking individuals with autism develop skills related to typed communication and achieving independent communication. The grant will also support the development of a pilot app, a multifaceted assessment tool that will aid in determining candidacy for facilitated communication training, current pointing skills and literacy levels. Finally, this project will focus specifically on the use of the iPad for helping individuals with autism develop greater physical independence when typing to communicate.

Sensory Perception Deficits and Cortical Coherence in Children with Autism: A Study of the 'Noisy Cortex' Hypothesis 

Autism is a behaviorally diagnosed disorder with defining impairments in socialization, interests, and communication abilities. Autism is also characterized by deficits in processing of simple visual and auditory information such as loudness discrimination or perception of moving dots, as well as complex visual and auditory information such as faces and language. Additionally, there is evidence of abnormal tactile sensitivity in autism. These functional findings are complemented by anatomical ones, the most robust of which is that the brains are large. Other neuroanatomical findings include neuroinflammation, and disrupted inhibitory circuitry. To date, no robust models have been formulated for either the neurobiological origin of the observed abnormalities, or the relationship between the pervasive anatomic abnormalities and the neural systems dysfunctions which are characteristic of autism. Furthermore, while the observed anatomical pathologies are distributed rather than localized, the vast majority of functional studies focus on localized features. The main objective of this project is to test the model that the neural substrates underlying the functional deficits of autism at the cortical level stem from a noisy cortex which has a poor signal to noise ratio. To this end, Dr. Kenet will employ magnetoencephalograpy (MEG) to record functional activation in response to sensory stimuli in children with autism and age matched controls. The central hypotheses are: (1) that the cortex of individuals with autism is inherently and internally a "noisy" cortex, i.e. a cortex with a low signal to noise ratio; (2) that the "noisiness" of the cortex is widely distributed rather than localized, resulting in widespread functional abnormalities; and (3) that from this distributed "noisy" cortex emanates a network in which connectivity is disrupted, with ensuing functional abnormalities that include widespread perceptual deficits, and alterations in neural circuitry that may drive higher order cognitive and social impairments emanating at least in part from abnormal network properties.

Exploring Communication Pathways in Nonverbal Individuals with Autism Spectrum Disorder: Speech and Print

To date, research in Autism Spectrum Disorder (ASD) has focused on individuals who are high functioning. Additionally, most of the research has been with infants and young children. In contrast, little is known about adult individuals on the spectrum who do not speak and may or may not have intellectual disabilities. These individuals pose a challenge to study due to compliance issues and difficulties with producing a reliable response. Additionally, they frequently present with co-morbid inattention, anxiety, aggression and sensory problems. Insofar as the ability to communicate is considered a positive prognostic indicator for individuals with ASD, Dr. Mody and colleagues focus their efforts on the neurobiology of communication deficits in nonverbal adults with ASD for a clearer understanding of the underlying disruptions for potential application in improved intervention. They take advantage of recent advances in neuroimaging using EEG, MEG, fMRI and DTI with passive paradigms, in the context of a novel combination of experiments targeting speech and print to assess the integrity of spoken and written communication pathways in the brain in nonverbal ASD. Specifically, nonverbal adults with ASD and age- and gender-matched neurotypical controls will participate in three experiments in which investigators will examine (a) oromotor representations for speech vs. non-speech; (b) access to meaning via print; (c) structural and functional intactness of speech and reading networks. Taken together, these experiments have the potential to reveal articulatory and orthographic mappings as related to speech-language deficits in nonverbal ASD.

Career Development Award for Elizabeth Torres

Natural behaviors flow continuously. They are dynamically composed of movements with different levels of intent, ranging from deliberately controlled motions to motions that spontaneously occur largely beneath our conscious awareness. The signatures of motor output variability from these movement classes carry an ever-changing blend of noise and signal that informs the central nervous system of critical changes at the periphery. They help discriminate sensory changes of relevance to the biological organism. The modulation and control of this efferent output flow depends on the returning afferent stream, which such motions themselves cause.

Although physical movements have been exclusively treated as efferent output in autism, they also constitute a form of sensory input that can be measured at the periphery in non-invasive ways. The returning afferent information can thus be precisely parameterized in a controlled manner and paired with other forms of sensory feedback to augment the sensory bubble of the autistic system. In this way, there is a higher probability of inducing perceptual stability along some sensory modality so as to create proper anchors or frames of reference to scaffold the type of sensory-motor integration processes that enable predicting ahead, in a causal manner, the sensory consequences of impending actions. In turn such feedback can be used to make the system cognizant of its own spontaneous actions and intentions, and of the spontaneous actions and the intentions of others in the social environment.

Recent work from Torres’ laboratory has taken the first steps towards this paradigm shifting approach to movement in autism. They have invented a new statistical platform for individualized behavioral analyses (SPIBA). This platform helps close the feedback loops in autism, to detect real-time changes in the internal somatosensation of the child as a function of external sensory guidance. SPIBA combined with physical body micro-movements that are hidden to the conscious human eye has helped shift the stochastic regimes of the autistic system from random and noisy to predictive and reliable, thus broadening the bandwidth of their peripheral motor-sensory signal. Even in 25 non-verbal children with ASD Dr. Torres’ team was able to systematically evoke volitional control of their actions and enhance intentionality in their spontaneous gestures, according to the shifts in the stochastic signatures of their motor output variability, the rate of which was unique to each child.

This project will combine SPIBA, the new conceptual framework for motor control and wearable sensing technology to open a window into the hidden communicative capacities of the autistic system. Torres’ lab will combine movement-based peripheral sensory feedback with precisely parameterized external sensory input to engage the autistic child in the intentional control of actions and decisions. The impact of the peripheral signal on centrally driven decisions will also be assessed.
