Neuroplasticity and Visual Constraints
Though I get pretty het up over the way dominant culture has disfavored vibration, I really don't care which biases humans want to rummage around with. Take your pick. But Feldenkrais is predictable: we're gonna want you to be in choice, to have three ways to do something. To get out of a rut, even for a fleeting moment. As with differentiating a standard muscle habit, when you let go of favoring one sense over the other, for even a moment, and then go back to your old pattern, the old pattern returns to you more smoothly.
You can differentiate one muscle system from another; you don't have to tighten your tongue when you squint your eyes. Likewise, you can differentiate almost anything you are aware of. This is how I design a 'neuroplasticity' lesson – to invite you to play with your sensorial 'architecture.' Visual architecture is not your only option for abstract thought – maybe we can use something different for a bit. And then, go back to what you were doing before. But, oh, you'll feel like your brain had a bath! Anyway, that's how I feel, and how my clients say they feel.
