2) #ChildRaising & #NARCISSISM
Defined: Self-centered, self-important. = Inflated sense of self.
Not necessarily at the clinical level, although some of the most dangerous people fall within this classification.
3) #ChildRaising & #NARCISSISM
Are narcissists insecure "deep down inside"? NO
They have high self-esteem, but only in individual/personal areas, NOT caring traits.
So glad this one came out! "After Midnight at the Zap Stop" by @ouranosaurus is an awesome story - full of late-night grease, and the luckless & the worthy. But also because it's a #neuroscience teaching opportunity. Might even be a #NeuroThursday!
One offhand line explains a technology as "stimulating a particular set of mirror neurons." Which works as a story element just fine. It sounds plausible and authoritative! But as a neuroscientist, I have strong opinions about #mirrorneurons. I don't think they're real.
To be clear, mine is a controversial opinion. Many neuroscientists would disagree. But it's a hill I'm willing to fight on, especially given how often "mirror neurons" crop up in popular science.
This phenomenon - when you look away from a moving thing, and you briefly see illusory motion in the other direction - is the "Motion Aftereffect," and it comes from some very basic brain maneuvers. Who wants to join me on going full #NeuroThursday here? en.wikipedia.org/wiki/Motion_af…
Most neurons in the brain (and elsewhere) do this thing called "adaptation," where they accept whatever's going on as the new normal. For example, if you sit down with your laptop on your lap, you'll soon stop noticing the weight.
This can arise from the crudest single-cell level: some ion channels in the cell membrane have negative feedback loops that self-dampen.
#NeuroThursday is back this week to talk about the #neuroscience of #synesthesia. What does it mean for a letter to have an intrinsic color, for a number to have a distance? And why the heck would this trait evolve in humankind?
Synesthesia is when "stimulation of one sense automatically provokes a secondary perception in another." The secondary perception can be direct ("9's are red") or associative ("9's make me think of red"), either counts.
Synesthesia comes in countless forms, but color-based are the most frequent. The most well-known is "grapheme-color" synesthesia, where a grapheme (written shape, e.g. letter or numeral) has a color - like the opening picture.
