Researchers implicate the hippocampus and nucleus accumbens in decisions that call for delayed gratification.
It is possible for those with anhedonia to enjoy experiences and feel pleasure, however, those with the disorder find it hard to maintain their positive emotions, a new study reports.
According to researchers, the brain learns to reproduce brain activity patterns that lead to reward. The findings could lead to new avenues for treating addiction and OCD, researchers report.
Analyzing the work of great philosophers and recent neuroscience research, researchers conclude certain simple features, such as symmetry and roundness, make things more attractive to us.
A new study reveals a brain region that contributes to anhedonia, the loss of pleasure, in those with depression. The study also shows how ketamine acts on this brain region, explaining why the drug appears to be so effective at treating anhedonia.
Researchers shed light on the dual nature of dopamine, as a neurotransmitter that makes us seek pleasure and also reinforces avoidance of pain.
What we find pleasurable may be down to our genetics. Researchers found nucleus accumbens activation and physical anhedonia were influenced by shared genes. The experience of pleasure and physical anhedonia also appear to share some of the same genes.
