Which of the following is associated with the neurodevelopmental model of schizophrenia? Group of answer choicesCognitive functions are most affected by the excess activity in the disinhibited mesolimbic pathway.Early damage to the indirect basal ganglia pathway results in the negative symptoms of schizophrenia.High mesolimbic DA activity following mesocortical cell loss may explain the dramatic positive symptoms of schizophrenia.The model attempts to identify the cause of the proposed early mesocortical cell loss.

Which model of schizophrenia integrates the neurochemical data with the neuroanatomical findings concerning the disorder? Group of answer choicesThe dopamine hypothesisThe glutamate-dopamine modelThe DA imbalance hypothesisThe neurodevelopmental model

The positive symptoms of schizophrenia are believed to be associated with: Question 5 options: Increased activity of the mesocortical dopamine pathway Decreased activity of the mesolimbic dopamine pathway Decreased activity of the mesocortical dopamine pathway Increased activity of the mesolimbic dopamine pathway

Which statement about glutamate and DA in regard to symptoms associated with schizophrenia is true? Group of answer choicesOverabundance of glutamate at the NMDA receptor may be a precursor to DA dysfunction and may explain increases in mesolimbic DA and decreases in PFC function.Insufficient glutamate at the NMDA receptor may be a precursor to DA dysfunction and may explain increases in mesolimbic DA and decreases in PFC function.NMDA receptors have indirect excitatory effects on of midbrain mesolimbic DA neurons that project to limbic regions.Schizophrenic symptoms are due to increased DA function in mesocortical neurons along with reduced DA function in mesolimbic dopaminergic neurons.

Name FOUR risk factors for developing schizophrenia.

In addition to their traditional motor program selection and implementation functions, the basal ganglia are also thought to be involved inGroup of answer choicesdrug-seeking behaviors.mood changes.initiation and termination of thought patterns related to planning and attention.disorders such as Tourette's syndrome and schizophrenia.All of the above
