Researchers have identified a novel neurotransmitter system in the brain. The system signals transmission of innate olfactory information to areas of the brain associated with emotional processing via the TAAR5 receptor. The findings could help in the development of new treatments for depression and schizophrenia.
Humans and mice use inference skills to solve problems in a remarkably similar manner.
Shorter sleep duration can increase the risk of children developing depression, anxiety, and cognitive problems. Children who routinely suffered sleep disruptions or shorter sleep durations had reduced brain volume in the orbitofrontal cortex, prefrontal cortex, precuneus, supramarginal gyrus, and temporal cortex.
The left and right brain areas are more similar in those with ASD. Reduced asymmetry was identified in cortical thickness across various brain regions in those on the autism spectrum.
Teens with psychosis spectrum disorders have significantly reduced surface areas in the orbitofrontal cortex, cingulate, precentral, and postcentral brain regions. MRI scans also revealed decreased thalamic volume.
White matter connectivity between the auditory processing areas and brain areas associated with reward may explain why we like, or dislike music.
The orbitofrontal cortex (OFC) appears to play a significant role in our ability to make decisions. A network connecting the OFC and nucleus accumbens translates negative outcomes into values, while the OFC-amygdala circuit helps stabilize action values.
Neuroimaging study of Spanish voters reveals negative political messages illicit stronger neural responses. Messages about corruption activate brain areas associated with risk and disappointment.
Female mice who experienced early life stress developed problems and had fewer neurons in areas of the brain responsible for regulating emotions and making sense of rules, researchers report.
A new study reports personality traits can help protect an individual's brain against symptoms of emotional distress, such as anxiety and depression.
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.
