Natureza ou Criacao? Novos estudos indicam que a criacao pode mudar a genetica imediatamente. Porem, a Matrix/DNA suspeita da experiencia

(obs: aqui vai dois links para dois papers, cada um sugerindo o contrario do outro. Enquanto um paper encontrou que a criacao modela a configuracao cerebral e Portanto os comportamentos, o outro paper encontrou que as cinco principais doencas mentais, como esquizofrenia, autism, bipolar desordem apresentam um mesmo padrao de expressao de genes, sugerindo que estas doencas tem causas geneticas. Mas pode ser que os papers falam de coisas diferentes pois os comportamentos com disturbio psicologico ou anormais sao uma coisa e estas doencas sao outra coisa.

Nature, meet nurture

Single-cell analysis reveals diverse landscape of genetic changes in the brain after a sensory experience

Is it nature or nurture that ultimately shapes an organism? A new study reveals a dramatic landscape of gene expression changes across all cell types in the mouse visual cortex after a sensory experience, many linked to neural connectivity and the brain’s ability to rewire itself to learn and adapt.

E’ a natureza genetica ou a criacao que realmente modela um organismo? Um novo estudo revela que dramaticas experiencias modificam a expresso de genes no cerebro, fazendo o cerebro se reconfigurar para aprender o novo e adaptar-se.

Louis Charles MorelliI think there is a big mistake in this study. The sensory experience can not evolve light or absence of it. The building blocks of biological genes came from a primordial building block made off just, only light. So, despite that we can’t see this light in the neurons, it must be there at its deep foundations. If I am right, it is obvious that outside light not configured like the internal light will force their changes. The sensory stimulus must be another thing, like a ferocious cat, etc.

Gene Expression Overlaps Among Psychiatric Disorders

Transcriptional profiling of post-mortem human brains reveals commonalities in the genes over- and under-expressed in schizophrenia, bipolar disorder, autism, and major depression. 

Neste estudo encontrou-se padroes comuns na expressao de genes nas doencas mentais
