I’ve just been laying back drooling to an alpha/gamma session. The zero-touch glasses and AKG headphones are the bestest combination I’ve yet used.

The session is a kind of puzzle. It’s a play on numbers. Lots of instances of a particular number in its structure. Some so subtle that if you listen for them, you can completely forget to hear anything else. And then when the brain gets bored with counting, there’s nothing but you and your thoughts, which have been gently nudged into a chosen mode, or rhythm.

Mine went to the brain as it often does. I’ve been thinking about rhythms and how they may relate to the “distance” from which a memory might have to be retrieved. As is, I suspect, a common error, I confined my model to the regions of the brain encased within the skull.

It is convenient to create an us-and-them scenario between the brain and the body, with a picture of all these robot-like appendages under the brain’s supervision and control. A mere twist of language facilitates the visualisation – neurons are brain-stuff, nerves are body-stuff.

But, of course, the animal that is I is not so conveniently subdivided. Nerves are but a particular type of neuron. Specialised, but having most of the same structure as any old neuron. Most importantly, they have an axon. The axon is the (hopefully) well-insulated conduit between the neuron’s input and its output. There are neurons with one end up in the skull and the other in our digestive tract – big cells! Most of our nerves don’t have a direct line, but arrive at ganglia in various locations, particularly at intervals up the spine, where initial message prioritisation is performed before being dispatched to “head office”.

Nearly all of my AVS experience has been focused on perception and consciousness, with only brief excursions into sensory awareness of body. There’s been many a time that I have had unexpected sensations, quivers and tremors while using AVS, and I’ve put them down to “just nervous twitches”. Ummm. “Just a nervous twitch” is fully a neural response, and thus its implications must be considered in light of the whole mental state at the time, and the stimuli present.

Why restrict AVS experimentation to the bit between the ears? The entire Central Nervous System is fair game!!!
