Tiempo y Consciencia

Tiempo y Consciencia

Esta representación del universo puede arrojar luz sobre cómo se forma en nuestra mente el concepto del tiempo, el flujo del tiempo, la separación del pasado, presente y futuro, y de la jerarquía de los presentes. La mente es un producto del cerebro, y el cerebro tiene una organización secuencial y limitada. El cerebro no puede captar ni la verdadera realidad, ni la verdadera totalidad.

The unknown brain: Von Economo neurons

The unknown brain: Von Economo neurons

At the end of the 19th century, the Ukrainian anatomist Vladimir Betz described a group of cells that attracted his attention because of their shape: “These spindle cells of the cingulate gyrus are notably larger (two or three times) than the other neurons of the V plate”. Similarly, the Spanish neuroanatomist Santiago Ramón y Cajal referred to them as “giant spindle cells” during his histological studies of the cerebral cortex.

HBP: The challenge of simulating the brain

HBP: The challenge of simulating the brain

In October 2013, the European Commission for the Future and Emerging Technologies (FET) launched an international research initiative with an ambitious goal: to simulate the human brain. With the Human Brain Project (HBP), the European Union established a state-of-the-art research platform to study the brain for 10 years, from molecular scales to higher cognitive processes.

Interneurons and Cerebral Circuits

Interneurons and Cerebral Circuits

Until about a decade ago, knowledge of this type of cell was merely descriptive. However, recent genetic and functional studies have established much better their properties and roles. Possibly, in the coming years, we will realize that they fulfill a more important function than we imagined, and like the little-studied glial cells, they could provide some clues about the genesis of CNS diseases.

How many cells are in our brains?

How many cells are in our brains?

Since the school years, the idea that neurons are the cells of the brain has entered our heads. Well, I think it is absolutely necessary that we start to change this very limited perspective on the central nervous system (CNS). In reality, the brain is composed of a diverse multicellular population, and although neurons add up to a significant number, the rest of the cells are by no means negligible.

The secrets of the brain

Lorem Ipsum is simply dummy text of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into electronic typesetting, remaining essentially unchanged. It was popularised in the 1960s...
