Most of the information on the effects of benzene center around its hematotoxic and genotoxic effects. However, its effect on central neurotransmitters is inconclusive in terms of cognitive behavior of the host.

This was paralleled with loss of short term memory, as evidenced by passive avoidance test, of the benzene treated animals.
