A phosphatase cascade by which rewarding stimuli control nucleosomal response

Neuron 242 Activation by Primary Rewarding Stimuli

[this issue of Neuron]). The structures included the do-pamine system, as many of the stimulation sites were in close proximity to axons of dopamine neurons or to amphetamine, and nicotine lead to increases in dopa-Cambridge CB2 3DY mine concentration in the ventral striatum and frontal United Kingdom cortex, which appears to be a crucial mechanism of drug addiction. In view of these well-estab...

Reward grabs the eye: Oculomotor capture by rewarding stimuli

It is well known that salient yet task irrelevant stimuli may capture our eyes independent of our goals and intentions. The present study shows that a task-irrelevant stimulus that is previously associated with high monetary reward captures the eyes much stronger than that very same stimulus when previously associated with low monetary reward. We conclude that reward changes the salience of a s...

Are In-group Social Stimuli more Rewarding than Out-group?

Projection-Specific Modulation of Dopamine Neuron Synapses by Aversive and Rewarding Stimuli

Midbrain dopamine (DA) neurons are not homogeneous but differ in their molecular properties and responses to external stimuli. We examined whether the modulation of excitatory synapses on DA neurons by rewarding or aversive stimuli depends on the brain area to which these DA neurons project. We identified DA neuron subpopulations in slices after injection of "Retrobeads" into single target area...

control of the optical properties of nanoparticles by laser fields

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
