Mechanism of Ammonia‐Induced Brain Damage in Chinese Striped‐Necked Turtle (Mauremys sinensis)

Integrative Zoology, EarlyView.
High levels of ammonia disrupt the integrity of the brain barrier in Mauremys sinensis, leading to tissue edema. This, in turn, triggers a series of cascade reactions, including disturbances in neurotransmitter levels, particularly glutamate, which might further exacerbate the neurotoxic effects.
