Introduction

On aimerait tous savoir parler plusieurs langues, par contre le problème est que quand j’ai envie de faire un bilan, toutes les langues que j’ai apprises paraissent manquer quelque choses pour qu’elles soient parfaites. Et bien, grace au principe du rasoir d’Ockham, j’écrirai comme je parle à moi-même, peu n’import quelle langue. D’un côté, cela demandera moins d’effort; de l’autre, cela me permettra exprimer mes réflexions brutes sans qu’ils soient partiellement cachées à cause de la honte ou alors la peur qu’on me juge.

Evolving thought

The perception of human society (updated)

6 minute read

Published:

Background

Years ago, I claimed that the world was running irrationally. I was 95% wrong. I want to update my thoughts on this point as I have been dwelling in the field of medicine and neuroscience for 4 years. We, humans, perceive nature through senses and cognition. I define cognition as the ability to reason, abstract, and communicate (information transfer). Scientifically, at least based on the literature to date, cognition is grounded on our sensations. For example, we like to make visual analogies to explain a concept, such as sphere-atom, river-time, and numerous 2D illustrations in scientific publications.

Existence

Prelude

We perceive the world through vision, sensation, sound, smell, taste. Mechanistically, the receptor of the cells senses the environment and transduce the signals/molecules/electrical activities to the brain. A fundamental problem of defining existence in the world is: how do we define the existence that can not beb sensed. I find a less intimidating way to formulate the question: if the signal from cell receptor takes a certain period to reach our brain, can we tell if the stimuli occurs at the present time.

Mind

Universal law in mind

Why do humans need to find the universal law (time-space for example)?

We are living in a complex world. Finding universal law often requires taking countless factors into account, which inevitably exceed human’s capacity to represent constructs in mind. For example, human’s spatial ability are three-dimensional. The Coordonnées cartésiennes is how we use to communicate the spatial property of an entity.
if a universal law existed, I am interested in if the the universal law requires that human transcends mind’s ability to represent existence.

An practical guide of statistical analyses in Neuroscience studies (for beginners)

47 minute read

Published:

Introduction

This notebook aims to provide statistical functions, build dataFrame, and perform statistical analyses. The conditions/groups are push/pull+ healthy/lf-patients/hf-patients/sham-patients + before/after-TMS The hypotheses tested are:

  • difference between healthy subjects and patients (includng lf/hf/sham-TMS) in push/pull epochs()
  • the regression between CMMN properties (including components-SPMIs and graph properties) and FMA
  • clustering analyses on CMMN properties (UE-brunnstrom clusters)
  • ANOVA and MANOVA and post-hoc analyses (details are missed)
