In 2004, a research group at Peking University First Hospital discovered a mutation in the gene coding for a sodium-channel ...

Today it seems self-evident that neurons make their electrical signals by opening gates of water-filled pores (ion channels) in the plasma membrane. But it was not always so. Remarkably ...

Opening and closing ion channels changes the membrane potential. When the neuron is triggered, it activates voltage-gated sodium channels at the beginning of the axon. This causes an influx of ...

When a neuron receives a stimulus ... Additionally, the authors identified two ion channels that are essential for the change of membrane voltages triggered by sensory stimulation.

Hence, researchers often simulate the brain as a network of coupled neural masses, each described by a mean-field model. These models capture the essential features of neuronal populations while ...

Scientists have uncovered a crucial pathway that links brain cell activity to the activation of genes responsible for ...

The nucleus where the genes that modify neuron function are controlled is ... mechanism involving the activation of receptors and ion channels generating calcium signals that rapidly communicate ...
