Episode #31 is here: Neural Pruning, Synesthesia, and Autism
What aspects of the brain differ between autistic people and non-autistic people? Do these brain differences lead to things like synesthesia in autistic people? Synesthesia is when your senses or perceptions overlap, like when you think of a number and see waves of red or some other colour. Or when you can feel in your own body the sensations and physical pain of another, just by looking at them!
In this episode, I also talk about ableist perspectives in autism research, secondary autism, neurons, glial cells, early brain development, mirror-touch synesthesia as the basis of deep empathy, and much more!

Kristen Hovet: 1:06
Today we’re talking about neural pruning and how it differs in the brains of autistics versus the brains of neurotypicals. I’ll also discuss synesthesia. I don’t know if I’m saying that right. I’m saying it. I think I tried getting Google Translate to help me and I’m still not saying it right. Actually, speaking of Google Translate, I think she’s going to help me in this episode, so I’m going to need her here. One sec, okay, synesthesia. Synesthesia, yeah, where one sensory or cognitive pathway activates a second or maybe even third sensory or cognitive pathway.
