Understanding how the brain creates a map of the space around us has implications for research into learning and memory disorders ranging from autism to Alzheimer's disease, where subjects often have an incorrect perception ...

Neurons in the brain play a role as an electric wire conveying an electrical signal. Because this electric wire is connected with various joints (synapse), various brain functions can occur. A neuron which has dendritic trees ...

(Medical Xpress)—When brain cells are overwhelmed by an influx of too many calcium molecules, they shut down the channels through which these molecules enter the cells. Until now, the "stop" signal mechanism that cells ...

It takes a village—of neurons—that is, to process sensory inputs in the brain. For example, when a line appears in our visual field, networks of neurons fire together and send messages throughout the brain to identify ...

Just as humans use their noses for the sense of smell, insects such as fruit flies use their antennae—covered in sensory hairs called sensilla—for olfaction. In flies, the sense of smell plays a fundamental role in courtship.

Researchers have identified a new mechanism controlling brain development: that neurons not only 'smell' chemicals in their environment, but also 'feel' their way through the developing brain.

Information flows in a well-defined direction in the brain: Chemical and electrical signals are passed from one neuron to the other across the synapse, from the pre-synaptic to the post-synaptic neuron. Now, Peter Jonas and ...
