This time in Jan 2022
With my Haas Scholars Cohort on the UC Berkeley Campus.
We were back to in-person meetings though fully masked indoors.
Implications for autism. Application and interventions is my big thought always.
I think by now it is pretty established that there are glitches in multisensory processing in autistics.
Past studies indicate TBW (Temporal Binding Window) larger in autistics - individual cortical columns were strong, but not talking to columns in other domains.
I want to highlight that this paper says that this balance between distributed vs local information can be a tool to explore differences in multisensory processing. The paper also goes on to say that this can be used to develop effective interventions aimed at improving performance on tasks requiring coordination between different sensory modalities.
So how exactly can we start to do this. What kind of experiment design can we set up so that we get to big goal of interventions. Do we first check for what regions of the brain are involved in autistics, while we do a task.
In a world of noise and chaos,
My mind is a storm, a tempest tossed.
The overwhelming sensation,
Meltdown, a state of frustration.
My senses heightened,
Sounds and lights, so brightened.
A cacophony of noise,
A confusion that destroys.
A feeling of impending doom.
As I try to find an escape room.
But there is no escape,
From this overwhelming state.
I am trapped in my mind,
A prisoner of my own fate.
Is there a glimmer of hope,
A lifeline to help me cope.
To regain control, and continue on
But in the middle of the meltdown, all that is long gone.
Pretty much every SLP I've been to over the years, has mentioned these terms. So what exactly are they.
Apraxia, dyspraxia, and oral-motor apraxia are all related to deficits in motor planning and execution, but they differ in their specific manifestations and underlying neural mechanisms.

Application to Autism.
The advantage of a good filtering system is less getting overwhelmed by your sensory environment in the real world, but the disadvantage was that you could lose out on critical information. This almost automatic value-based filtering ability is, I think, an issue many autistics like me struggle with. But even with extensive experience, value-based filters could vary around task domain, context-specific or even things like predictability. Which is still, i think, why we still face challenges in trying to understand what exactly is going on in the non-neurotypical populations.
Summary of the paper we discussed in my Multisensory Integration seminar this week.
