An instructive way to investigate the relationship between catecholaminergic function and psychiatric disorder has involved behavioral responses to experimental catecholamine depletion (CD).
Moreover, this safe and well-tolerated pharmacological challenge appears to be well-suited to study the relationship between the catecholaminergic function and neuropsychiatric conditions in future studies using neuropsychological tasks and functional neuroimaging.
Plausible explanations for the association between catecholaminergic genes and working memory, but not IQ, therefore involve the specific neural underpinnings of the different tasks, and the complexity of gene expression within different regions of the brain.
Neither lesion had any significant effects on catecholaminergic function in any of the five other brain regions from which tissue samples were taken.
We saw that different functions had very different "bold scores" — both between functions and between men and women in the same function.
The facility will be divided equally between the cafe/restaurant function and the coffeehouse/entertainment function.
Specifically, we found a pair of TH-positive cells in the ventral region of the thoracic ganglion, and in ventral and dorsal regions of the abdominal (pleonic) ganglion, suggesting catecholaminergic modulation of claws' function and abdominal structures.
A1: Note that there is a difference between a nature-given function and a designated function.
The immediate and marked response of ADHD symptoms to stimulant medications such as amphetamines and methylphenidate, which increase levels of synaptic dopamine, suggests that the main underlying pathophysiological process may involve deficits or imbalances in catecholaminergic, dopaminergic, and nicotinergic functioning [ 109- 111].
Abnormal functioning of catecholaminergic and serotonergic neurotransmission has been reported in both ADHD and ASD [ 14, 66, 72].
