The Limits of Neuroplasticity in the Brain

Posted by in categories: biological, neuroscience, science

New research shows that the brain‘s neuroplasticity isn’t as flexible as previously thought.

One of the brain’s mysteries is how exactly it reorganizes new #information as you learn new tasks. The standard to date was to test how neurons learned new behavior one #neuron at a time.

Carnegie Mellon University and the University of Pittsburgh decided to try a different approach. They looked at the population of neurons to see how they worked together while #learning a new behavior. Studying the intracortical population activity in the primary motor cortex of rhesus macaques during short-term learning in a brain–computer interface (BCI) task, they were able to study the reorganization of population during learning.

The Neurogenesis Debate

Written by Nicholi Avery

On March 7 2018, a study was published in the highly esteemed journal Nature by an international team of scientists claiming that #neurogenesis starts to rapidly decline in the #human brain as early as 13 years old and becomes undetectable in adults. This rocked the scientific community as there has been a long-established theory that neurogenesis takes place throughout the course of life in the mammalian #brain. Until the 1990s, neurologists were practicing their profession under the doctrine established in the late 19th to early 20th century by the prominent histologist Ramon y Cajal, often referred to as a god of neuroscience;

Losing Your Mind? Great Thinkers on the Brain

Posted by in categories: biological, biotech/medical, cryonics, neuroscience, philosophy, science, theory

Aristotle is frequently regarded as one of the greatest thinkers of antiquity. So why didn’t he think much of his brain?

In this brief history of the brain, the GPA explores what the great minds of the past thought about thought. And we discover that questions that seem to have obvious answers today were anything but self-evident for the individuals that first tackled them. And that conversely, sometimes the facts which we simply accept to be true can be blinding, preventing us from making deeper discoveries about our our world and ourselves.
