(2022) argues that changes in dopamine release during stimulus pre-exposure reflect non-associative changes in attention to the conditioned stimulus that are causally related to latent inhibition effects. Associative accounts of pre-exposure-induced changes in associability suggest, ...
Dopamine release related to motivation is rapidly and locally sculpted by receptors on dopamine terminals, independently from dopamine cell firing. Target neurons abruptly switch between learning and performance modes, with striatal cholinergic interneurons providing one candidate switch mechanism. The ...
If dopamine is not able to cross the blood brain barrier, how does it get into the brain? How are Lewy bodies and dopamine related? What is a biological reaction due to a stimulus? What stimulates ADH release? How long does it take for dopamine receptors to recover? Which neurotransmitter...
Dysfunction in various dopaminergic systems is known to be associated with various disorders. Reduced dopamine in the pre-frontal cortex and disinhibited striatal dopamine release is seen in schizophrenic patients. Loss of dopamine in the striatum is a cause of the loss of motor control seen in Pa...
Yet recent studies have shown that dopamine conveys motivational value and promotes movement even on subsecond timescales. Here I describe an alternative account of how dopamine regulates ongoing behavior. Dopamine release related to motivation is rapidly and locally sculpted by receptors on dopamine ...

Addictive drugs share with palatable food the property of increasing extracellular dopamine (DA), preferentially in the nucleus accumbens shell rather than in the core. However, by acting directly on the brain, drugs bypass the adaptive mechanisms (habituation) that constrain the responsiveness of accu...

What does dopamine deficiency really mean? As we have seen, dopamine is a neurotransmitter and hormone that helps to carry chemical messages between nerve cells in the brain or between the brain and the other parts of the body. It plays a crucial role in various bodily functions. These includ...
Does sex release dopamine?Dopamine triggers feelings of arousal, motivation, and reward. If you find sex pleasurable, your body releases a rush of dopamine in response to those good physical feelings.
