Two well-known neurochemicals found to be involved in sub-second perception, cognition

In first-of-their-kind observations in the human brain, an international team of researchers has revealed two well-known neurochemicals - dopamine and serotonin - are at work at sub-second speeds to shape how people perceive the world and take action based on their perception.

Study elucidates the role of ERβ in growth of skeletal muscle in female mice

Researchers at Kumamoto University, Japan generated mice lacking the estrogen receptor beta (ERβ) gene, both fiber-specific and muscle stem cell-specific, which resulted in abnormalities in the growth and regeneration of skeletal muscle in female mice.

Scientists discern molecular mechanisms underlying plant parasitism, cross-species grafting

Using the model Orobanchaceae parasitic plant Phtheirospermum japonicum, scientists from Nagoya University and other research institutes from Japan have discerned the molecular mechanisms underlying plant parasitism and cross-species grafting, pinpointing enzyme β-1,4-glucanase (GH9B3) as an important contributor to both phenomena.

Nerve cell activity indicates the confidence in decisions

Should I or shouldn't I? The activity of individual nerve cells in the brain tells us how confident we are in our decisions. This is shown by a recent study by researchers at the University of Bonn.

NTHU research could have significant impact on the treatment of dementia

One of the causes of neurodegenerative diseases such as Parkinson's and Alzheimer's is the calcification of the basal nucleus of the brain, which blocks the membrane protein channels on the surface of brain cells, preventing the transmission of signal molecules and nutrients to the cells.

Research team discovers a new key player in long-term memory

A McGill-led multi-institutional research team has discovered that during memory consolidation, there are at least two distinct processes taking place in two different brain networks - the excitatory and inhibitory networks.

Researchers create p16-Cre ERT2 -tdTomato mouse model to characterize in vivo senescent cells

Cell senescence is a state of permanent cell cycle arrest that was initially defined for cells grown in cell culture. It plays a key role in age-associated organ dysfunction and age-related diseases such as cancer, but the in vivo pathogenesis is largely unclear.
