Cysticercosis is a sickness caused by ingesting the tapeworms found in pork. When tapeworm larvae spreads to the human brain, it is a very serious problem resulting in a condition referred to as neurocysticercosis. If a tapeworm infestation problem exists, there are medications sold over-the-counter for this problem.
Glutamate. Glutamate is an excitatory relative of GABA. It is the most common neurotransmitter in the central nervous system-as much as half of all neurons in the brain-and is especially important in regards to memory. Curiously, glutamate is actually toxic to neurons, and an excess will kill them.
Glutamate is the principal excitatory neurotransmitter in mammalian brain and has long been implicated in the generation of epileptic discharges. Administration of glutamate or glutamate analogues to experimental animals can elicit seizures, whereas glutamate antagonists are both anticonvulsant and neuroprotective (1).
