Science and Its Philosophy From a Marxist Perspective
Source:Netherlands Institute for Neuroscience A new study at the Netherlands Institute for Neuroscience has examined how the dopamine system processes aversive unpleasant events. It is well known that the dopamine system plays a crucial role in motivation, learning and movement. One of the main functions of dopamine is to predict the occurrence of rewarding experiences and the […]
What Happens to the Dopamine System When We Experience Aversive Events?
Source:Max Planck Institute Selfless behavior and cooperation cannot be taken for granted. Mohammad Salahshour of the Max Planck Institute for Mathematics in the Sciences (now at Max Planck Institute of Animal Behavior), has used a game theory-based approach to show why it can be worthwhile for individuals to set self-interests aside. One of the most fundamental […]

Interesante artículo, sin embargo, debe tenerse cuidado de no caer en la tentación del reduccionismo. Tentación a la que parecen sucumbir los investigadores cuando señalan que “la conciencia debe investigarse con las mismas herramientas matemáticas que los físicos usan para otros fenómenos relativistas conocidos”. A pesar de ello, “Ella no usa órganos sensoriales, mide sus representaciones neuronales directamente por la interacción entre una parte de su cerebro con otras partes. Mide sus representaciones neuronales según sus relaciones con otras representaciones neuronales.” es un notable hallazgo en términos de la relación del todo y las partes y en términos de que lo fundamental en los fenómenos son sus relaciones internas. Esto refuerza diversos principios del Materialismo Dialéctico.
Source: Bar-Ilan University How do 1.4 kg of brain tissue create thoughts, feelings, mental images, and an inner world? The ability of the brain to create consciousness has baffled some for millennia. The mystery of consciousness lies in the fact that each of us has subjectivity, something that is like to sense, feel and think. […]

The announcement that US President’s Biden’s Inflation Reduction Act (IRA) has got the backing of pro-business, coal-mining owner Democratic Senator Manchin has been greeted with a wave of optimism that the US target of cutting carbon emissions in half before the end of this decade (or 40% compared with 2005 levels), can be met. “This bill will really turbocharge that transition to clean energy, it will transform markets where already solar PV, wind and batteries are in many cases cheaper than incumbent fossil fuels,” said Anand Gopal, executive director of policy at Energy Innovation, an open source research body. “Increasingly I’m more optimistic that keeping the temperature rise under 2C (3.6F) is more reachable. 1.5C is a stretch goal at this point.”
The bill will cut US emissions by between 31% and 44% below 2005 levels by 2030, according to Rhodium Group, a non-partisan research firm. A separate…

A BOOK WITH MANY SIDES
Review by Gunnel Minett
The average adult human brain weighs about 1.5 kg and accounts for about 2% of the adult body weight. It is very similar in shape and form for most human beings. Still it is unique to each individual. By the time a child is born the brain has billions of neurones that are wired together through trillions of interconnections into what can only be described as the most sophisticated supercomputer we can only begin to imagine.
This book describes the journey from the fertilised egg to the moment a new human being is born, and beyond. It is written by an experimental neurobiologist, describing the development of neurobiology which has lead to the increase in understanding of human evolution as well as the human brain.
Still, the story of how this development takes place is filled…

Source:Frontiers A new study has linked life satisfaction to the chemistry in our brains. People that release more of the neurochemical oxytocin are kinder to others and tend to be more satisfied with their lives. In addition, oxytocin release increases with age, showing why, on average, people are more caring as they get older. These […]
