Selective modulation of excitatory and inhibitory microcircuits by dopamine.
Dopamine plays an important role in the working memory functions of the prefrontal cortex, functions that are impacted in age-related memory decline, drug abuse, and a wide variety of disorders, including schizophrenia and Parkinson's disease. We have previously reported that dopamine depresses excitatory transmission between pyramidal neurons in the prefrontal cortex. Here, using paired record...
متن کاملEffects of common excitatory and inhibitory inputs on motoneuron synchronization.
We compared the effects of common excitatory and inhibitory inputs on motoneuron synchronization by simulating synaptic inputs with injected current transients. We elicited repetitive discharge in hypoglossal motoneurons recorded in slices of rat brain stem using a combination of a suprathreshold injected current step with superimposed noise to mimic the synaptic drive likely to occur during ph...
متن کاملDopamine depresses excitatory and inhibitory synaptic transmission by distinct mechanisms in the nucleus accumbens.
The release of dopamine (DA) in the nucleus accumbens (NAc) is thought to be critical for mediating natural rewards as well as for the reinforcing actions of drugs of abuse. DA and amphetamine depress both excitatory and inhibitory synaptic transmission in the NAc by a presynaptic D1-like DA receptor. However, the mechanisms of depression of excitatory and inhibitory synaptic transmission appea...
