Getting serious with retinopathy: approaching an integrated hypothesis for central serous chorioretinopathy.
Medical Hypotheses(2013)
Abstract
Development of the prefrontal cortex is believed to play an important role in the maturation of higher cognitive functions such as decision making, cognition and control of part of the neural element of the stress response. The prefrontal cortex undergoes considerable maturation during childhood, including a reduction of synaptic and neural density, a growth of dendrites, and an increase in white matter volume, thereby forming distributed neural networks appropriate for complex cognitive processing, but maturation is not complete until approximately 25years of age. Serotonin and its receptors (HTRs) play critical roles in brain development and in the regulation of cognition, mood, and anxiety. HTRs are highly expressed in the human prefrontal cortex and exert control over prefrontal excitability. Studies of post-mortem prefrontal brain tissue found distinct developmental patterns of expression of these receptors occurring in early postnatal development and also into adulthood. The general pattern of improved cognitive control and emotion regulation with maturation of the prefrontal cortex, suggests a linear increase in development from childhood to adulthood. Animal studies have shown that dopamine is crucial for communication between the accumbens, amygdala, and prefrontal cortex. Dopamine projections to the prefrontal cortex continue to develop into early adulthood.
