Dopamine and Creativity


“lower thalamic gating thresholds, resulting in decreased filtering and autoregulation of information flow and, increase excitation of cortical regions through decreased inhibition of prefrontal pyramidal neurons. The decreased prefrontal signal-to-noise ratio may place networks of cortical neurons in a more labile state, allowing them to more easily switch between representations and process multiple stimuli across a wider association range. This state, which we hereforth will refer to as the “creative bias”, could benefit performance on tasks that involve continuous generation and (re-)combination of mental representations and switching between mind-sets
