Synapse, the name for the signal-receiving site on a neuron, comes from the Greek word for contact. Neuroscientists used to maintain that neurons form one-to-one relationship to contact one another....

The neurons in this video contain a dye that fluoresces when it encounters calcium ions. When the neuron is excited, calcium floods into the cell and the neuron fluoresces. The researchers monitored...

Dopamine Pathways
2 May 2013 - 15:34
In the brain, dopamine helps regulate reward and body movement. As part of the reward pathway, dopamine is produced by neurons in the ventral tegmental area (VTA) and released in the nucleus...

Spiny Neurons Receive Dopamine
2 May 2013 - 15:30
The dendrite branches of spiny neurons are littered with spines, or receptor sites, for neurotransmitters, including dopamine. Spiny neurons play a crucial role in initiating and regulating movements...

These cells grown from embryonic mouse cortex have beautiful green stained dendrites but the red stain would show the presence of spines as lines of dots along the dendrites.  In this control...
