Neuroplasticity in the Digital Era

Dr. Sharon Sucharitha Gold Nemalladinne

ABSTRACT:

Neural networks are formed through neural connections or linking of neurons through the formation of synapses. In essence, they are an interconnected group of neurons which together coordinate global behaviour. The rapid proliferation of internet technologies has transformed human behaviour through neural reinforcement and addiction pathways. Frequent use of the internet for the purpose of interaction via social media or online gaming or use of online streaming platforms is found to result in changes pertaining to reward processing, attention regulation and executive control by activating dopaminergic circuits involved in reward anticipation and receipt. Over time, this reinforcement can lead to compulsive use patterns, characterized by increased tolerance, craving, and withdrawal-like symptoms when access is limited.
Neuroimaging studies reveal alterations in the structure and function of key brain regions, such as the prefrontal cortex and striatum which are associated with decision-making, impulse control, and reward valuation. These neural changes parallel those observed in other behavioral addictions, indicating that excessive internet use may result in maladaptive plasticity within cognitive control networks. Current research findings indicate that internet usage is inversely proportional to sustained attention, working memory capacity, and deep processing capabilities. This could be a result of rapid task switching and multitasking which cause cognitive overload and hence decrease neuroplasticity. Shifts in learning strategies, with increased preference for immediate over delayed rewards and decreased tolerance for monotonous or effortful tasks is also evidenced by research.
Considering the evidence, it is understood that pervasive internet engagement has severe effects on reinforcement mechanisms and cognitive processes which in turn have important implications regarding mental health, educational outcomes and societal functioning.
