Two porous coordination polymers, {[Zn8(L)2(H2O)11]·6DMF·5H2O}n (Zn-1) and {[Co2(H4L)(H2O)4]·4DMA}n (Co-2), have been successfully constructed by using elongated aromatic-rich ligand methanetetrayl(biphenyl-3,5-dicarboxylic acid) (H8L) Zn(NO3)2·6H2O or Co(NO3)2·6H2O. Single-crystal X-ray diffraction results reveal that polymer Zn-1 has a three-dimensional skeleton, in which the two different dual core paddle-wheels [Zn2(COO)4] [Zn2(COO)3] are linked eight-connected node L8– anions, assembling into (3, 4, 8)-connected 3D metal organic framework with irregular channels. The complex exhibits excellent recognition ability for dopamine through luminescence quenching mechanism high KSV (4.61 × 103 M–1) limit of detection (9.24 10–5 M). Moreover, it also shows anti-interference properties amino acid solutions. In Co-2, secondary building units [Co2(COO)4(H2O)] four connected nodes H4L4– interconnected assembled (4, 4)-connected containing rectangular channels size 12.2 9.6 Å2 along [001] direction. addition, Co-2 selective adsorption cationic dyes, rhodamine B (RB+) methylene blue (MB+).

Various mathematical models have been formulated to describe the changes in synaptic strengths resulting from spike-timing-dependent plasticity (STDP). A subset of these include a third factor, dopamine, which interacts with spike timing contribute at specific synapses, notably those cortex striatum input layer basal ganglia. Theoretical work analyze has largely focused on abstract issues, such as conditions under they may promote synchronization and weight distributions induced by inputs simple correlation structures, rather than scenarios associated tasks, generally not considered dopamine-dependent forms STDP. In this paper we introduce three dopamine-modulated STDP adapted previously proposed rules. We then analyze, mathematically simulations, their performance biologically relevant scenarios. test ability each maintain its weights face noise complete reward prediction action selection studying learned corresponding task setting. Interestingly, find that rule is well suited studied but falls short others. Different tasks therefore require different plasticity, yielding precise form mechanism present vary across regions striatum, other brain areas impacted are involved distinct computational functions.
