A student is completing revision notes about the communication between neurons in the system that Eysenck linked to psychoticism.
| Stage | Sequence |
|---|---|
| 1 | An electrical impulse reaches the end of the sending neuron. |
| 2 | Small sacs open and release chemical X into the synapse. |
| 3 | Chemical X crosses the gap and attaches to structures labelled Y on the receiving neuron. |
| 4 | If enough of structures Y are occupied, the receiving neuron fires an electrical impulse. |
Name chemical X.
State the name of structures Y.
