Gait is a sensory-motor function, which needs the adequate interaction between major systems for:
1⃣ Generating force
2⃣ Orientation in space
3⃣ Refine force
4⃣ Collate and interpret sensory information; select and modify motor programs

But first, what is phenomenology?
That is a term that refers to the description of the movement. Instead of trying inmmediately to put a label on what you see, first I suggest start by watching and describing. 🤔

Sleep is divided in 4 phases, each of them is repeated during the 🌕in a cycle.
N1: vertex waves
N2: sleep spindles, k complexes
N3: slow-wave-sleep (restorative phase)
REM: rapid horizontal eye movement occurs, we dream and there is no muscle tone

What is the root cause of migraines? Currently 'TBC', unfortunately.
But evidence suggests it involves neurological, vascular, hormonal and genetic factors are working in concert
Applies to pretty much anything in the brain, it never makes it easy

But if there IS one specific 'root cause' of migraines, most fingers point to Cortical Spreading Depression, CSD
What's that?
It's when a neuron, brain cell, experiences a sudden burst of activity (depolarisation), followed by a period of inactivity, as if it's exhausted

Empathy, as in recognising, understanding, and *sharing* the emotional state/experience of others, is a vital ability of the human brain. It makes us what we are.
However, one problem is, that our own emotions and experiences can distort the process.

However, one problem is, that our own emotions and experiences can distort the process.
Here's more #BrainStuff

A surprising amount of our brain's processes are geared towards detecting, recognising, and recreating the emotions of others. We're constantly, often without realising, broadcasting our inner state, and human brains have evolved to recognise and interpret these cues.

As I say, we often don't even realise this is happening. You ever walked into a room after a huge argument has happened and immediately felt uncomfortable, or noted a 'frosty atmosphere'? That's what's happening there.

Why do we readily remember someone's face, but regularly struggle to remember their name?
What makes names so hard to remember, when far less salient/important/useful stuff is often recalled so readily?

When you meet someone, they tell you their name. But very rarely is that the only information dispensed by the encounter. A conversation normally ensues, where a lot of basic personal info is exchanged. Their name is a small part of this.

There is variant of JC virus that will attack the granule cells in the cerebellum causing a lot of the same symptoms. Here we demonstrate the need for good clinical history & a f%^&* smart neurologist. We see a plethora of PML, IRIS, HIV encephalopathy but this is new one for me
Educar sin premios ni castigos es posible, si crees que castigo es pegar y dar premios es equivalente a reforzar.🤦♂️ Decir que el condicionamiento es malo por eso, es divulgar sobre algo que se desconoce y hacer una irresponsabilidad como divulgador y como periódico. (Dentro hilo)
Para empezar, dar un premio no es reforzar, y castigar no consiste en hacerle algo desagradable a alguien. Yo puedo darle "un premio" (Y lo pongo entre comillas, porque sería dar algo socialmente considerado como premio, p.e.: un diploma o una Copa) y estar justamente castigando.
El problema esta en considerar que estamos reforzando (procedim. Operante) por dar un premio (social) y confundir castigo (procedim. Operante) con castigar (dar palos). Se entiende que sea difícil de comprender, porque tampoco se han puesto los mejores nombres como p. operante.
