Virtually modelling the human brain in a computer

Neurons that remain active even after the triggering stimulus has been silenced form the basis of short-term memory. The brain uses rhythmically active neurons to combine larger groups of neurons into functional units. Until ...

Does physical activity influence the health of future offspring?

Physical and mental exercise can affect the learning ability of future offspring, at least in mice. This particular form of inheritance is mediated by certain RNA molecules that influence gene activity. These molecules accumulate ...

New model for the origin of grid cells

Ludwig Maximilian University of Munich neurobiologists present a new theory for the origin of the grid cells required for spatial orientation in the mammalian brain, which assigns a vital role to the timing of trains of signals ...

How sensorimotor intelligence may develop

It is fascinating to observe a robot exploring its physical possibilities and surroundings, and subsequently developing different self-taught behaviors without any instructions. In their paper published on October, 26, 2015 ...

Study visualizes mRNA transport in test tube

(Phys.org) —Much of biomedical science – both mystifying and awe-inspiring to the lay public – depends on an unwavering focus on things that can't be easily seen, like the inner-workings of cells, in order to determine ...

RNA on the move

In the fruit fly Drosophila, oskar mRNA, which is involved in defining the animal’s body axes, is produced in the nuclei of nurse cells neighbouring the oocyte, and must be transported to the oocyte and along its entire ...
