Dopamine News and Research RSS Feed - Dopamine News and Research

Dopamine is a hormone and neurotransmitter occurring in a wide variety of animals, including both vertebrates and invertebrates. In the brain, this phenethylamine functions as a neurotransmitter, activating the five types of dopamine receptors — D1, D2, D3, D4 and D5, and their variants. Dopamine is produced in several areas of the brain, including the substantia nigra and the ventral tegmental area. Dopamine is also a neurohormone released by the hypothalamus. Its main function as a hormone is to inhibit the release of prolactin from the anterior lobe of the pituitary. Dopamine has many functions in the brain, including important roles in behavior and cognition, motor activity, motivation and reward, inhibition of prolactin production (involved in lactation), sleep, mood, attention, and learning. Dopaminergic neurons (i.e., neurons whose primary neurotransmitter is dopamine) are present chiefly in the ventral tegmental area (VTA) of the midbrain, substantia nigra pars compacta, and arcuate nucleus of the hypothalamus.
Researcher develops nature-inspired adhesive that stays sticky when wet

Researcher develops nature-inspired adhesive that stays sticky when wet

Even the strongest glues collapse when soaked. Just watch a band-aid slide ungracefully off a finger or toe while in the shower. However, with support from the Office of Naval Research, one researcher has developed a nature-inspired adhesive that stays sticky when wet. [More]
Study reveals way to actively reverse anesthetic-induced unconsciousness

Study reveals way to actively reverse anesthetic-induced unconsciousness

The latest study from a Massachusetts General Hospital/Massachusetts Institute of Technology team investigating the mechanisms underlying general anesthesia finds that stimulating a specific group of neurons in mice produces signs of arousal -- including getting on their feet and walking -- even as the animals continue to receive the anesthetic drug isoflurane.

Researchers find new way to rapidly awaken patients after general anesthesia

Researchers find new way to rapidly awaken patients after general anesthesia

The use of general anesthesia for surgery has not changed fundamentally since it was first introduced 170 years ago. Patients are still left to come around in their own time following withdrawal of the drug. [More]

Immunotherapy already in clinical trials for cancer could slow progression of Parkinson's disease

Researchers at Johns Hopkins report they have identified a protein that enables a toxic natural aggregate to spread from cell to cell in a mammal's brain — and a way to block that protein's action. [More]

Lund University stem cell researcher awarded Fernström prize for study on repairing damaged brain

Lund University stem cell researcher awarded Fernström prize for study on repairing damaged brain

Is it possible to convert a patient’s own skin cells into functioning nerve cells? Or insert healthy genes to reprogram the cells of a damaged brain? Stem cell researcher Malin Parmar at Lund University in Sweden is studying these types of issues, in close collaboration with clinical researchers. [More]

Tendency to feel lonely linked partially to genetic traits

Loneliness is linked to poor physical and mental health, and is an even more accurate predictor of early death than obesity. [More]
UC Irvine study shows how YHS effectively treats different forms of pain

UC Irvine study shows how YHS effectively treats different forms of pain

Root extracts from the flowering herbal plant Corydalis yanhusuo, or YHS, has widely used for centuries as a pain treatment. Yet few studies have investigated how it works on different forms of pain, and little is known about its molecular mechanisms. [More]
