How good are neuron models?

How good are neuron models?

Neuroscience

By Jorge Mejías

For several decades now, physicists, mathematicians, neurobiologists and other specialists have been joining efforts to build realistic mathematical models of neurons. A typical model consists on one or several differential equations that are able to predict the evolution of the membrane potential of a neuron for a given input. When introduced in a computer, these […]

Strange as it may sound to many people, the fact is that some of the most interesting work on epistemology that is being currently done in Spain is carried out at the headquarters of the Spanish gendarmerie (the well known force called Guardia Civil), in particular, at the Area of Statistics within the corps’ Service […]

Artificial intelligence (AI) is one of the most actives fields of computer science. The idea of a computer learning, in an autonomous way, complicate tasks is exciting from both the fundamental and applied points of view. One very recent and interesting approach to this problem is Deep Learning . This technology is becoming popular very […]

Scientists use 3D printer to create networks of artificial cells Researchers have developed networks of water droplets that can act like biological tissue cells. The researchers created the networks using a three-dimensional printer. The networks can support up to 35,000 droplets and have the potential to be a scaffold for growing synthetic tissues or a […]

Reinforcement learning in the brain

Neuroscience

By Jorge Mejías

The term reinforcement learning is well known among researchers in the areas of machine learning and artificial intelligence. It refers to a type of algorithms which are designed to solve a task by maximizing some kind of reward. In a simplified way, we could say that a typical reinforcement learning algorithm works as follows: our […]

Do I flower now or do I wait a little bit more?

Biology

By Daniel Marino

Flowers are the reproductive organs of angiosperms (flowering plants) and flowering is therefore the phenomenon by which the undifferentiated cells from the meristems (similar to animal stem cells) differentiate into a floral meristem that will then produce the different components of the flower (sepals, petals, stamens and carpels). This transition from a plant vegetative to […]

By Daniel Manzano

Quantum computers are one of the most promising technologies under development, and all their promises are completely justified. Quantum systems are extremely expensive to compute, where “expensiveness” can be measured either by the memory or the computational time required in classical computers. But it should be much cheaper if the computer uses quantum mechanics rules […]
