What is the Origin of Working Memory Fortification?

The concept is rooted in cognitive psychology, which defined working memory as a key component of executive function, distinct from long-term memory. The idea of 'fortification' stems from neuroscience research demonstrating that working memory capacity is plastic and can be improved through specific interventions that enhance the functional connectivity within the prefrontal-parietal network. This approach bridges psychological training with physiological optimization.

What is the Mechanism of Working Memory Fortification?

Working memory relies on the sustained, synchronous firing of neurons within the prefrontal and parietal cortices, often mediated by the neurotransmitter dopamine, which enhances the signal-to-noise ratio of relevant neural activity. Fortification protocols typically involve N-back or dual-task training to increase the efficiency of these neural circuits. Furthermore, ensuring optimal levels of hormones and neurotrophic factors, such as BDNF, supports the structural integrity and synaptic plasticity necessary for robust working memory function.

Working Memory Fortification

Meaning

The clinical process of systematically strengthening the brain’s capacity to temporarily hold and manipulate a limited amount of information relevant to the current task, a function essential for complex reasoning, planning, and decision-making. Fortification involves both targeted cognitive training and the optimization of underlying neurobiological factors, such as neurotransmitter levels and neural connectivity, to increase the efficiency and capacity of this crucial cognitive resource. It is a direct strategy for enhancing intellectual performance.
