Amor: Corazón o Cerebro

AMOR:

CORAZÓN O CEREBRO.

"Amo como ama el amor. No conozco otra razón para amar que amarte. ¿Qué quieres que te diga además de que te amo, si lo que quiero decirte es que te amo?

Fernando Pessoa.

El amor, ah que bonito es sentir mariposas en el estómago, nuestro corazón palpitar rápidamente, sonrojarnos al ver a esa persona especial, estoy segura que la mayoría de nosotros hemos estado o están enamorados.

"Un corazón que ama nunca envejece".

Pero realmente amamos por el corazón?, estudios muestran lo contrario y nos dicen que amamos por el cerebro.

“Hay que escuchar a la cabeza, pero dejar hablar al corazón”. Marguerite Yourcenar

Aunque se sientan mariposas en el estómago y el corazón palpite, el amor empieza en la cabeza. El cerebro manda señales y libera sustancias tales como la noradrenalina, la dopamina, la oxitócica, la vasopresina, que generan ese estado de confusión y entusiasmo.

Georgina Montemayor Flores, investigadora de la Facultad de Medicina de la UNAM, explica que en las primeras etapas del amor perdemos la razón porque “se activan las zonas que controlan emociones, como el tálamo, la amígdala, el hipotálamo, el hipocampo, el giro cingulado (responsable de la asociación de memorias a olores y al dolor) y las partes del sistema límbico (principal responsable de nuestra vida emocional, y la formación de memorias)”.

El llamado amor verdadero, explica la especialista, llega cuando se produce en el cerebro la feniletilamina que se encarga de inundarnos de dopamina, esta sustancia es el neurotransmisor responsable de los mecanismos de refuerzo del cerebro, es decir, de la capacidad de desear algo y de repetir un comportamiento que proporciona placer. Mientras estamos enamorados también liberamos serotonina que nos lleva a un aumento progresivo del bienestar y la felicidad con mayor estímulo sexual.

Así que ya saben el próximo San Valentín ustedes pueden regalar como algo original cerebros o cerebros en forma de corazón, bueno creo que eso no importa, sólo vivan y disfruten el amor.

Political fanaticism.

Political fanaticism. In recent years, a very latent phenomenon that has been growing dangerously and vertiginously, in a context of high polarization; this distorter is presented as an enemy of electoral conscience and a healthy and mature democracy, it is political fanaticism. But let's start by defining fanaticism: According to the definition of the Royal Spanish Academy : it is an “excessive passion and tenacity in the defense of beliefs or opinions, especially religious or political ones”. For Voltaire: “Fanaticism is to superstition what delirium is to fever, what rage is to anger. He who has ecstasies, visions, who takes dreams for realities and his imaginations for prophecies is a novice fanatic with great hopes; he may soon get to kill for God's sake." Therefore, fanaticism is identified by the desire to impose their ideas, despise those who are different, be based on a series of thoughts that are unquestionable, have a square view of t

Earthquakes-Mexico

Earthquakes in Mexico. In Mexico along with other countries, earthquakes are very common and this is because it is part of the Belt or Ring of Fire, located on the coasts of the Pacific Ocean and is characterized by concentrating some of the most important subduction zones of the world, which causes an intense seismic and volcanic activity in the areas covered.
