- Synapses
- What are they?
- Synapses are gaps in between neurons.
- Synapses transmit signals in between nerve cells, by way of a chemical micro-transmitter
- Impulse Travel
- First, an electrical impulse travels along an axon.The nerve ending releases neurotransmitters. the chemicals diffuse across the synapse and bind with receptor molecules on the membrane of the next neuron. This stimulates the second neuron to transmit the electrical impulse
- Receptor molecules only bond to specific transmitters
- Ecstasy and anti-depressents
- Ecstasy blocks the serotonin receptor sites in the synapses in the brain. This prevents the serotonin from being absorbed by the receptor molecules. As a result, the level of serotonin in the synapse increases.
- Anti-depressents cause serotonin concentration to build up in synapses. They block the re-uptake of serotonin from a synapse.
- Serotonin is a hormone that promotes a feeling of happiness and well-being. it is released when you feel happy or important.
