Input: Consider Input: Tardive dyskinesia (TD) is a movement disorder characterized by abnormal involuntary facial movements induced by chronic therapy with classical antipsychotic medications. Currently, there is no satisfactory pharmacotherapy for TD, which represents a major limitation to therapy with classical antipsychotics. In order to develop or optimize therapies for TD, and to develop new APDs with lower indices of motor side effects, the pathology underlying TD must first be understood. The use of animal models has been used to further this objective. Here, we review different preparations that have been used to model TD and discuss the contribution of neuroimaging studies conducted in these models. Studies in animal models have lead to several hypotheses of TD pathology, although none has yet emerged as the ultimate underlying cause of this syndrome. We discuss alterations in functional indices, neuron and synapse morphology and changes in specific neurotransmitter systems that have been described in animal models of TD, and outline how these findings have contributed to our understanding of antipsychotic-induced dyskinesias. We conclude that several non-mutually exclusive theories of TD are supported by animal studies, including increases in oxidative stress leading to structural and functional changes in specific neurotransmitter systems. Elucidating the mechanisms underlying TD neuropathology partly through the use of animal models will lead to the development of APDs with superior side effect profiles or more effective therapies for TD.

Input: Consider Input: Coming off their win over the 49ers the Falcons flew to Cleveland Browns Stadium for an Interconference duel against the Cleveland BrownsAfter a scoreless 1st quarter, the Falcons got things started in the 2nd quarter. Matt Bryant converted a 24-yard field goal. The Browns replied and took the lead with QB Seneca Wallace's 19-yard TD pass to RB Peyton Hillis. The Falcons tried to cut the lead when Bryant made a 30-yard field goal, but was expanded again in the 3rd quarter with kicker Phil Dawson hitting a 19-yard field goal. After that, the Falcons scored when QB Matt Ryan connected with WR Roddy White on a 45-yard TD pass. The game was a defensive drag out the rest of the way. In the 4th quarter DE Kroy Biermann returned an interception 41 yards to the endzone for a touchdown, sealing the Falcons' 4th straight win.
Output: Which player scored the second longest field goal?
