Changing Cognitive Capacity

Changing cognitive capacity through very specific stimulation that targets certain processing areas means the brain can be changed at a physiological level, does this infer that without a learning disability, the brain is progressively gaining higher functionality throughout life or are there constraints such as age that could impede the process no matter how much stimulation is experienced.

The idea of a permanently plastic brain has not always been supported throughout time, though in the last decade, there has been increasing research supporting the idea that experiences do not just change our emotions and perceptions towards our surroundings, but they can actually change the underlying neuroanatomical structure of our …show more content…

(2012), 41 healthy adults older than 65 were trained by physical, cognitive, and relaxation tasks, to observe their executive functional changes by recording electrical activity of their brains and the potential magnitudes of 3 different protein (P3b, Ne,N2) which are associated with neural functions most prone to decline with age. They trained 2 times a week for 1.5 hours over 4 months; they found that there’s improvement in focus, accuracy, speed of tasks, and task-switching; all of which were seen most significantly with the neurocognitive exercises since the increase in the amplitude of potentials was most consistent with this type of training. Their research supports the idea that through demanding stimulation of the cortical areas, gaining higher cognitive ability is possible and by incorporating a variety of methods to evaluate, including subjective questionnaires, the positive impacts are clearly …show more content…

One difference in their approach is the method used for their studies. The first, used electrical brain activity changes as a quantitative parameter after an intensive multiple domain training program that took into account all the main qualitative cognitive abilities that are known to decline with age. They also chose to experiment on humans as models for their study, and this was very effective in terms of portraying the positive outcomes of their study, especially since the data was analyzed based on multiple types of induced effects and their correlations to one another such as behavioural and electrical potential amplitudes, which further helped them consider the error rates and have a more accurate claim. The second study, used mice as models for their study and mostly considered the quantitative parameters of plasticity. Using LTP synaptic strength decline that was induced by modulating astrocyte signalling, as the argument that there is a decline in synaptic plasticity and cognitive function with age. Based on these two studies alone, the first has a stronger claim as to why their experiment supports the argument made, though in the second, the physiological relevance in only
