In the original FARS model, working memory and task-specific associations in prefrontal cortex bias grasp execution by modulating the grasp selection in F5 such that those grasps appropriate for the current task are selected.
Noradrenergic neurons that project from the locus coeruleus to the prefrontal cortex release norepinephrine which helps to guide behaviour by modulating the transfer of information through neuronal circuits that are responsible for selective and sustained attention [ 40].
In prefrontal cortex (PFC) and striatum DA is involved in the expression of synaptic plasticity by modulating the amount of long-term potentiation (LTP) and depression (LTD) of glutamatergic synapses [15], [16], [17], [18], [19].
Moreover, they indicate that the salience of unconditioned rewarding or aversive natural stimuli, graded by modulating the intrinsic properties of the stimulus or the motivational state of the organism, is directly related to the increase of prefrontal NE outflow.
By modulating the sound, that pocket can be moved around, changing the position of the bead.
The system works by modulating the LED lighting in your home or office.
By modulating the flux through the loop,the cavity frequency is modulated.
Increased 5HT and DA synthesis were observed in the prefrontal cortex and hippocampus of mice after the inhalation of lemon oil vapor (a species from the Citrus genus), suggesting that lemon oil vapor possibly affects the response to DAnergic activity by modulating the 5HTnergic system [ 49].
We aimed to investigate further this hypothesis by modulating directly prefrontal cortex excitability using transcranial direct current stimulation (tDCS) – a non-invasive, neuromodulatory tool that induces polarity-dependent changes in cortical excitability – and measuring effects on salivary cortisol and heart rate variability as proxies of the HPA and SAM systems.
Dopamine is further involved in memory processes by modulating neurons in the prefrontal cortex that are active during the delay interval between a stimulus presentation and a response [ 44], and may regulate working memory and attention [ 13, 45].
