Question 1

DeltaFosB

Answer 1

“But the actual molecular switch that initiates many ofthe lasting brain changes is the protein DeltaFosB.[124]Dopamine surges trigger DeltaFosB’s production. It then accumulates slowly in the reward circuitry in proportion to the amount of dopamine released when we chronically indulge in natural rewards[125] (sex,[126] sugar,[127] high fat, [128] aerobic exercise[129]) or virtually any drug of abuse. DeltaFosB takes a month or two to dissipate, but the changes it causes can remain.

“It turns on a very specific set of genes that physically and chemically alter the reward centre.[130] Think of dopamine as the foreman on a construction site barking the orders and DeltaFosB as the construction workers who actually pour the cement.”
