“…Furthermore, social norms are thought to be represented in the LPFC, and this area plays a key role in rule-based control 39 40 . In line with this notion, a recent study showed that anodal transcranial direct current stimulation (tDCS) of dorsal LPFC increases the sunk cost effect 41 . Therefore, tight coupling between these two regions might bias decision-making under the influence of sunk costs.…”

The sunk cost effect, an interesting and well-known maladaptive behavior, is pervasive in real life, and thus has been studied in various disciplines, including economics, psychology, organizational behavior, politics, and biology. However, the neural mechanisms underlying the sunk cost effect have not been clearly established, nor have their association with differences in individual susceptibility to the effect. Using functional magnetic resonance imaging, we investigated neural responses induced by sunk costs along with measures of core human personality. We found that individuals who tend to adhere to social rules and regulations (who are high in measured agreeableness and conscientiousness) are more susceptible to the sunk cost effect. Furthermore, this behavioral observation was strongly mediated by insula activity during sunk cost decision-making. Tight coupling between the insula and lateral prefrontal cortex was also observed during decision-making under sunk costs. Our findings reveal how individual differences can affect decision-making under sunk costs, thereby contributing to a better understanding of the psychological and neural mechanisms of the sunk cost effect.

“…For example, human and nonhuman primate value choices are subject to various biases such as framing effects (De Martino et al, 2006), choice repetition biases (Padoa-Schioppa, 2013; Samuelson and Zeckhauser, 1988), sunk cost effects (Bogdanov et al, 2015), and previous payoff biases (Noorbaloochi et al, 2015; Rorie et al, 2010). These biases, which become more pronounced with difficult decisions (Fleming et al, 2010; Padoa-Schioppa, 2013), are also observed in human perceptual decision making (Nicolle et al, 2011; Fleming et al, 2010; Noorbaloochi et al, 2015; Mulder et al, 2012; St John-Saaltink et al, 2016; Akaishi et al, 2014), with correlational evidence for a link between neural and choice variability (St John-Saaltink et al, 2016; Hesselmann et al, 2008; Wyart and Tallon-Baudry, 2009).…”

Animals and humans have a tendency to repeat recent choices, a phenomenon known as choice hysteresis. The mechanism for this choice bias remains unclear. Using an established, biophysically informed model of a competitive attractor network for decision making, we found that decaying tail activity from the previous trial caused choice hysteresis, especially during difficult trials, and accurately predicted human perceptual choices. In the model, choice variability could be directionally altered through amplification or dampening of post-trial activity decay through simulated depolarizing or hyperpolarizing network stimulation. An analogous intervention using transcranial direct current stimulation (tDCS) over left dorsolateral prefrontal cortex (dlPFC) yielded a close match between model predictions and experimental results: net soma depolarizing currents increased choice hysteresis, while hyperpolarizing currents suppressed it. Residual activity in competitive attractor networks within dlPFC may thus give rise to biases in perceptual choices, which can be directionally controlled through non-invasive brain stimulation.DOI: http://dx.doi.org/10.7554/eLife.20047.001

“…Anodal tDCS applied on the DLPFC facilitate working memory processes [11]. Findings show that anodal tDCS over the right DLPFC may prevent working memory impairment induced by acute stress [12]. Stimulation of the primary motor cortex (M1) and dorsolateral prefrontal cortex (DLPFC) reduces the perception of pain.…”

Transcranial direct current stimulation (tDCS) is a type of electrical modulation of the nervous system activity which involves the uses of low current to stimulate specified areas of the brain using electrodes to the scalp. This study was carried out to investigate if tDCS which is being used in the treatment of various disorders of the brain could have any possible side effects that might be worse than the treated disorder or any effects of tDCS on the cytoarchitecture of the dorsolateral prefrontal cortex. A total of 32 adult male Wistar rats were used and were placed into 5 groups (A-E). Rats in group A were divided into two groups A (SHAM) (tDCS for 30seconds) and A (N-SHAM). Rats in groups B, C, D and E were stimulated for 5, 10, 15, and 20 minutes with 12Volt respectively for the duration of 14 days and the animals were euthanized on the last day of the experiment two hours post brain stimulation. The specimen were subjected to gross morphological analysis and basic demonstration of the DLPFC using H & E and special stains. There was no significant difference in the neuronal structure and the supporting cells of the brain across the groups A (SHAM), B (5MINS), C (10MINS), D (15MINS), E (20MINS) when compared with control group A (N-SHAM) which suggest that tDCS does not have any neurodegenerative effects and could be safe in its use as neuro-stimulator to enhance cognitive ability in healthy individuals.
