Your Brain Is On the Brink of Chaos - Nautilus

In one important way, the recipient of a heart transplant ignores its new organ: Its nervous system usually doesn’t rewire to communicate…
Artur Alves's insight:

«Order and disorder enjoy a symbiotic relationship, and a neuron’s firing may wander chaotically until a memory or perception propels it into an attractor. Sensory input would then serve to “stabilize” chaos. Indeed, the presentation of a stimulus reduces variability in neuronal firing across a surprising number of different species and systems, as if a high-dimensional chaotic trajectory fell into an attractor. By “taming” chaos, attractors may represent a strategy for maintaining reliability in a sensitive system. Recent theoretical and experimental studies of large networks of independent oscillators have also shown that order and chaos can co-exist in surprising harmony, in so-called chimera states.

The current research paradigm in neuroscience, which considers neurons in a snapshot of time as stationary computational units, and not as members of a shifting dynamical entity, might be missing the mark entirely. If chaos plays an important role in the brain, then neural computations do not operate as a static read-out, a lockstep march from the transduction of photons to the experience of light, but a high-dimensional dynamic trajectory as spikes dance across the brain in self-choreographed cadence.«

Inspired by scientific studies, ordinary people are buying and building devices to send electrical current into their brains. Some say it has improved their memory and focus. Others have found relief from depression and chronic pain. But are they getting ahead of the science?

Adventures In Behavioral Neurology—or—what Neurology Can Tell Us About Human Nature | Conversation | Edge

Adventures In Behavioral Neurology—or—what Neurology Can Tell Us About Human Nature | Conversation | Edge | Gentlemachines | Scoop.it

Neurology is my kind of frontier: "Even Freud was a behavioral neurologist. We usually think of him as a psychologist, but he was also a neurologist. In fact, he began his career as a neurologist, comparable in stature with Charcot, Hughling Jackson, Kurt Goldstein. What they did was to look at patients with sustained injury to a very small region of the brain—and this is what we do as well in our lab. What you get is not a blunting of all your mental capacities or across the board reduction of your mental ability. What you get often is a highly selective loss of one specific function, other functions being preserved relatively intact. This gives you some confidence in saying that that region of the brain is specialized in dealing with that function."
