What Dreams May Come.

Interrogating the Dream Anyone who caught my talk at Ratio back in 2017 might vaguely recall a curious claim: that the Human corpus callosum—that bundle of neurons connecting our cerebral hemispheres—has a bandwidth in the same ballpark as that of a modern cell phone, once you take noise correction and synaptic redundancy into account. I […]

The Split-brain Universe

An extended Nowa Fantaskyka remix. The year is 1982. I read Isaac Asimov’s newly-published Foundation’s Edge with a sinking heart. Here is the one of Hard-SF’s Holy Trinity writing— with a straight face, as far as I can tell— about the “consciousness” of rocks and trees and doors, for Chrissakes. Isaac, what happened? I wonder. […]

HemiHive, in Hiding

If you’ve been following my writing for any length of time, you’ll know how fascinated I am by Krista and Tatiana Hogan, of British Columbia. I’ve cited them in Echopraxia’s end notes, described them in online essays; if you caught my talk at Pyrkon last year you might remember me wittering on about them in […]

Dolphinese

This is how you communicate with a fellow intelligence: you hurt it, and keep on hurting it, until you can distinguish the speech from the screams. —Blindsight Believe it or not, the above quote was inspired by some real-world research on language and dolphins. Admittedly the real-life inspiration was somewhat less grotesque: scientists taught a […]

Insect Awakenings.

Another PSA announcement: If anyone’s trying to email me, I’m not ignoring you. I haven’t got email for going on 4 days now. Alleged attempts by Dreamhost (the ISP that hosts rifters.com) to fix the problem have so far succeeded in changing its status from from “Everything’s pretty much cool, just a bit of leftover […]

No Brainer.

For decades now, I have been haunted by the grainy, black-and-white x-ray of a human skull. It is alive but empty, with a cavernous fluid-filled space where the brain should be. A thin layer of brain tissue lines that cavity like an amniotic sac. The image hails from a 1980 review article in Science: Roger […]

False Prophecy

(…being another reprint of a months-old Nowa Fantaskya column, because I’m still in Vancouver and haven’t yet had time to do my epic comparison of Fury Road and Kingsman) I’ve been called a prophet now and again. Articles about neuron cultures running robots or power grids generally provoke a comment or two about the “smart […]

Desperately Seeking Citation.

Can anyone point me to an anecdote about an introvert who manifested a sudden extrovertian personality change (cracking jokes, hitting on the nurses) when one of his cerebral hemispheres was anesthetized prior to brain surgery? I’m almost certain it hails from one of Ramachandran’s books, but I can’t find the damn thing and it’s relevant […]

Psychotic Dreams and Strange Extremes

Where do you start with dreams? People say you’re asleep when you dream, but you’re not really; it’s just that the input you’re consciously processing is generated internally, instead of coming from outside. It’s a kind of consciousness that believes the most ridiculous things, though. Your best friend doesn’t look anything like your best friend […]

Sleepwalk to Enlightenment

Judging by the number of links I’ve received, a lot of you are already familiar with this paper on consciousness and the claustrum. Or at least you’re familiar with the tsunami of popsci coverage it’s received. For the rest of you, the tale goes something like this:  54-year old female epileptic, seizure-free for four years […]
