Salsolinol modulation of dopamine neurons
Salsolinol, a tetrahydroisoquinoline present in the human and rat brains, is the condensation product of dopamine and acetaldehyde, the first metabolite of ethanol. Previous evidence obtained in vivo links salsolinol with the mesolimbic dopaminergic (DA) system: salsolinol is self-administered into the posterior of the ventral tegmental area (pVTA) of rats; intra-VTA administration of salsolino...
متن کاملDopamine modulation via memristive schematic
In this technical report we present novel results of the dopamine neuromodulation inspired modulation of a polyaniline (PANI) memristive device excitatory learning STDP. Results presented in this work are of two experiments setup computer simulation and physical prototype experiments. We present physical prototype of inhibitory learning or iSTDP as well as the results of iSTDP learning.
متن کاملA theoretical view on Dopamine Modulation
Dopamine modulation is taken as a test case for the possible function of 'slow' synapses of single neurons. We discuss possible innuences on diierent receptor types on computational properties of single neurons. Furthermore implications for networks of spiking neurons concerning temporal synchronization processes are also discussed.

متن کاملModulation of striatal projection systems by dopamine.
The basal ganglia are a chain of subcortical nuclei that facilitate action selection. Two striatal projection systems--so-called direct and indirect pathways--form the functional backbone of the basal ganglia circuit. Twenty years ago, investigators proposed that the striatum's ability to use dopamine (DA) rise and fall to control action selection was due to the segregation of D(1) and D(2) DA ...
