I'm currently reading the textbook about neuroscience. I find this scientific topic fascinating. I decided to summarize some extracts from the textbook that I find particularly interesting. I don't know whether it is appropriate to publish such specific texts here, but I would be glad to get grammar corrections.

GABA and glycine are responsible for the inhibition in the brain. Inhibition should be tightly regulated in the brain. Too much inhibition leads to a coma and too little inhibition leads to seizures. Therefore GABAa receptor has beside the receptor site binding to GABA other receptor sites binding to chemicals that modulates the function of GABAa receptor. For example,such drugs as benzodiazepines and barbiturates bind to other receptor sites of GABAa receptor and modulate its function. However, these drugs are capable of doing it only in the presence of GABA. Benzodiazepines increase the frequency of channel openings and barbiturates increase the duration of channel openings. The result in each case is more inhibitory CL current, more postsynaptic inhibition and therefore certain behavioral consequences of the inhibition.
