Malathion is an acetylcholinesterase inhibitor, a diverse family of chemicals.Upon uptake into the target organism, it binds irreversibly to the serine residue in the active catalytic site of the cholinesterase enzyme.
Carbaryl is a cholinesterase inhibitor and is toxic to humans. It is classified as a likely human carcinogen by the United States Environmental Protection Agency (EPA.) [13] The oral LD 50 is 250 to 850 mg/kg for rats and 100 to 650 mg/kg for mice. [8] Carbaryl can be produced using methyl isocyanate (MIC) as an intermediary. [5]
Malathion is an organophosphate parasympathomimetic which binds irreversibly to cholinesterase. Malathion is an insecticide of relatively low human toxicity.

All mammals, including humans, have four different lobes in their cortex: occipital, parietal, temporal, and frontal lobes. All four of these lobes play a key role in the functioning of our brain.
The periaqueductal gray (PAG), also known as the central gray, is a brain region that plays a critical role in autonomic function, motivated behavior and behavioural responses to threatening stimuli. [1] [2] PAG is also the primary control center for descending pain modulation. It has enkephalin-producing cells that suppress pain.
The human brain is the central organ of the nervous system, and with the spinal cord, comprises the central nervous system. It consists of the cerebrum, the brainstem and the cerebellum. The brain controls most of the activities of the body, processing, integrating, and coordinating the information it receives from the sensory nervous system ...
