Yuri Popov — as we remember him

As we may remember

How we remember what we can do

According to the motor simulation theory, the knowledge we possess of what we can do is based on simulation mechanisms triggered by an off-line activation of the brain areas involved in motor control. Action capabilities memory does not work by storing some content, but consists in the capacity, rooted in sensory-motor systems, to reenact off-line action sequences exhibiting the range of our po...

The fibrocyte in pulmonary hypertension: we seek him here, we seek him there.

T he fibrocyte is one of many populations of bone marrowderived cells that can be detected in the peripheral blood and is considered to represent a mesenchymal progenitor cell [1]. The fibrocyte, as we currently understand this term, was originally described by BUCALA et al. [2] in 1994 and is defined by the expression of a variety of cell surface antigens, including the stem cell marker CD34, ...

What we remember from a stressful episode.

A stressful episode is thought to be consolidated better because of a stress-induced activation of the hypothalamus-pituitary-adrenal (HPA) axis. However, human experimental studies addressing this hypothesis directly are lacking. Thus, we investigated memories of the stressful episode itself. Furthermore, we aimed to determine the influence of stress on recollection and familiarity processes. ...

Neurons that Remember How We Got There

In this issue of Neuron, Daie et al. (2015) show that the eye velocity-to-position neural integrator not only encodes the position, but also how it was reached. Representing content and context in the same neuronal population may form a general coding principle.
