Neuropsychological studies highlight the importance of the prefrontal cortex in abstract reasoning ability. The prefrontal cortex is anatomically connected to the basal ganglia through a series of parallel loops. The dorsolateral prefrontal cortex shares relatively greater connectivity with the caudate head, and it has been proposed that the caudate head may be more sensitive to executive proce...
Probabilistic category learning engages neural circuitry that includes the prefrontal cortex and caudate nucleus, two regions that show prominent changes with normal aging. However, the specific contributions of these brain regions are uncertain, and the effects of normal aging have not been examined previously in probabilistic category learning. In the present study, using a blood oxygenation ...
The prefrontal cortex (PFC) is implicated in a variety of cognitive and executive operations. However, this region is not a single functional unit; rather, it is composed of several functionally and anatomically distinct networks, including anterior cingulate cortex (ACC), medial prefrontal cortex (mPFC), and orbitofrontal cortex (OFC). These prefrontal subregions serve dissociable behavioral f...
Children with ADHD symptoms prefer smaller and immediate gain rather than bigger and long-term ones. This problem would result in impulsive behaviors and decision making. The aim of this study was to show the effect of transcranial Direct Current Stimulation (tDCS) on DLPFC and VMPFC on Improvement of delay discounting in children with Attention Deficit and Hyperactivity Symptoms.In this study...
aim of this research was exploring effect of transcranial direct current stimulation (tdcs) on working memory (wm) in dorsolateral prefrontal cortex (dlpfc) region in healthy people.the method used in this research was experimental with random assignment and control group. the population was male students of kharazmi university in range of 18 to 23 years old. thirty participant undertook three ...
Although several studies have examined the subcortical circuitry underlying Pavlovian-to-instrumental transfer (PIT), the role of medial prefrontal cortex in this behavior is largely unknown. Elucidating the cortical contributions to PIT will be key for understanding how reward-paired cues control behavior in both adaptive and maladaptive context (i.e., addiction). Here we use bilateral lesions...
Little is known about projections from the cerebral cortex to the trigeminal mesencephalic nucleus (Vmes) which contains the cell bodies of primary sensory afferents innervating masticatory muscle spindles and periodontal ligaments of the teeth. To address this issue, we employed retrograde (Fluorogold, FG) and anterograde (biotinylated dextranamine, BDA) tracing techniques in the rat. After in...
Adaptive behavior involves interactions between systems regulating Pavlovian and instrumental control of actions. Here, we present the first investigation of the neural mechanisms underlying aversive Pavlovian-instrumental transfer using fMRI in humans. Recent evidence indicates that these Pavlovian influences on instrumental actions are action-specific: Instrumental approach is invigorated by ...
