When we listen to a moving piece of music or feel the gentle pulse of a haptic vibration, our bodies react before we consciously register the feeling. The heart may quicken and palms may sweat, resulting in subtle electrical ...

Brain's mechanical properties influence synapse formation and electrical signal development, study finds

In the brain, highly specific connections called synapses link nerve cells and transmit electrical signals in a targeted manner. Despite decades of research, how synapses form during brain development is still not fully understood.
