What is the Origin of Prefrontal Cortex Activity Modulation?

This concept is derived from functional neuroimaging and cognitive neuroscience, where the 'Prefrontal Cortex' is the target area, and 'Modulation' implies regulating its activity level. Hormones like cortisol and testosterone exert direct influence on PFC excitability.

What is the Mechanism of Prefrontal Cortex Activity Modulation?

Modulation occurs via altering neurotransmitter availability—particularly dopamine and norepinephrine—at PFC synapses, a process governed by the endocrine state. For instance, optimal DHEA or testosterone levels support the dopaminergic tone necessary for sustained attention and working memory capacity within the PFC network.

Prefrontal Cortex Activity Modulation

Meaning

Prefrontal Cortex Activity Modulation refers to the precise adjustment of neural firing rates and functional connectivity within the brain region responsible for planning, decision-making, and working memory. Since this area is highly sensitive to hormonal fluctuations, modulation aims to restore optimal executive function often compromised by endocrine dysregulation. We seek to calibrate the brain’s highest control center.
