Boffins Find Evidence for Novel Brain Cell Communication

...d to inhibit one another, on the other hand. The excitation and inhibition take place because the activity of nerve cells leads to the release of particular chemicals, called neurotransmitters, which act as a classic means of communication between nerve cells, and lies at the base of most of current understan...

$1.5 Million Grant to Yale for Narcolepsy-Neurotransmitter Study

...igh levels of release might swing the tide over to excitation and increase cognitive arousal. However, on another target, NPY neurons, hypocretin directly excited the cells, byt dynorphin had little direct effect. Rather, dynorphin contributed to increased nerve cell activity by reducing the release of inhibi...

Discredited Drug may Be Used to Aid Mental Development in Down’s Syndrome Patient

...excited. In general, learning involves neuronal excitation in certain parts of the brain. Says Garner "For example, caffeine, which is a stimulant, can make us more attentive and aware, and enhance learning." PTZ does this by causing more GABA to be available in the brain. Overdoing this process can cau...
