What is the Origin of Brain Sensitivity?

This concept is rooted in the physiological study of neuroendocrinology and receptor pharmacology, where 'sensitivity' quantifies the relationship between the concentration of a substance and the resulting biological effect. It acknowledges that biological response is not solely dependent on circulating hormone levels but also on the target tissue's capacity to perceive and transduce the signal.

What is the Mechanism of Brain Sensitivity?

Brain sensitivity is fundamentally regulated by the density, affinity, and post-translational modification of specific neural receptors. For instance, chronic exposure to high levels of a hormone can lead to receptor downregulation, effectively decreasing brain sensitivity. Conversely, receptor upregulation can increase sensitivity. Maintaining optimal brain sensitivity is crucial for balanced mood, cognitive function, and appropriate hypothalamic-pituitary-gonadal axis feedback.

Brain Sensitivity

Meaning

The degree to which neural tissue responds to circulating chemical messengers, including neurotransmitters, hormones, and neurosteroids. High or low brain sensitivity dictates the magnitude of the central nervous system’s reaction to a given concentration of a signaling molecule. This responsiveness is dynamic, modulated by factors such as genetic polymorphisms, chronic stress, and hormonal milieu.
