Traumatic brain injury (TBI) causes persistent neurobehavioral deficits and increases the risk of psychiatric disorders, including depression, anxiety, and cognitive dysfunction linked to disrupted neuroplasticity, neuroinflammation, and serotonergic (5-HT) signaling.

This scoping review aimed to explore the various applications of...
A single non-anaesthetic dose of ketamine, a non-competitive NMDA receptor (NMDAR) antagonist with hallucinogenic properties, induces cognitive impairment and psychosis, and aggravates schizophrenia symptoms in patients. In conscious rats an equivalent dose of ketamine induces key features of animal models of acute psychosis, including hyperlocomotor activity, deficits in prepulse inhibition...
