Unraveling the reward behavior: Mechanisms underlying the dopamine signaling pathway

Researchers discover that the phosphorylation of a newly identified protein kinase substrate downstream of the dopamine signaling pathway regulates the brain reward behavior.

What is the effect of hierarchy on moral behavior?

Researchers show that powerful hierarchical situations make it easier to commit harmful actions, as agency and empathy are split across multiple individuals.

Omega-3 fatty acids, and in particular DHA, are associated with increased attention scores in adolescents

Docosahexaenoic acid (DHA) is associated with a greater capacity for selective and sustained attention in adolescents, while alpha-linolenic acid (ALA) is associated with lower impulsivity, according to a new study. The results confirm the importance o…

New model of Alzheimer’s as an autoimmune disease

Scientists have proposed a new mechanistic model (AD2) for Alzheimer’s, looking at it not as a brain disease, but as a chronic autoimmune condition that attacks the brain.

The neural cartography of smell

Rendering the invisible visible is among scientists’ favorite challenges. In their efforts to uncover how the olfactory system makes sense of thousands of otherwise invisible odors, scientists now have uncovered more of the cellular and molecular steps…

Study IDs what brings our senses and thoughts together

Our ability to think, decide, remember recent events and more, comes from our brain’s neocortex. Now neuroscientists have discovered key aspects of the mechanisms behind these functions. Their findings could ultimately help improve treatments for certa…

Anxiety during pregnancy can lead to earlier births, study finds

Women who experience anxiety about their pregnancies give birth earlier on average than those who don’t, according to new research.

Findings explain exceptional auditory abilities in Williams-Beuren Syndrome

Scientists have identified the mechanism by which Williams-Beuren Syndrome enhances the ability to discriminate between sounds as interneuron hyperexcitability in the auditory cortex.

Study findings suggest association between exposure to air pollution — particularly in the first 5 years of life — and alterations in brain structure

A study has found an association, in children aged 9-12, between exposure to air pollutants in the womb and during the first 8.5 years of life and alterations in white matter structural connectivity in the brain. The greater the child’s exposure before…

A new understanding of the neurobiology of impulsivity

While not all impulsive behavior speaks of mental illness, a wide range of mental health disorders which often emerge in adolescence, including depression and substance abuse, have been linked to impulsivity. So, finding a way to identify and treat tho…
