The time babies spend in the womb is far from idle. The brain is changing more rapidly during this time than at any other time in development. It is an active time for the fetus to grow and explore, and of course connect to its mother. And new evidence from in-utero fetal brain scans shows, for the first time, that this connection directly affects brain development: A mother’s stress during pregnancy changes neural connectivity in the brain of her unborn child.

For the first time, a neural link between altruism and empathy toward strangers
Giving up a kidney to a stranger requires a certain sense of selflessness, what’s come to be known in social science as extraordinary altruism. University of Pennsylvania psychologist Kristin Brethel-Haurwitz wanted to understand the connection between this trait and empathy, specifically empathy for distress emotions. Continue reading “For the first time, a neural link between altruism and empathy toward strangers”
Childhood trauma linked to impaired social cognition later in life for patients with major psychiatric disorders
A new report published in European Psychiatryidentified a significant association between childhood adversity and impaired social cognitive functioning among adults diagnosed with major psychiatric disorders. Through a comprehensive review of all research conducted to date, the investigators established that a traumatic early social environment frequently leads to social cognitive problems and greater illness severity for individuals with schizophrenia, bipolar disorder, borderline personality disorder, major depressive disorder, or post-traumatic stress disorder. Continue reading “Childhood trauma linked to impaired social cognition later in life for patients with major psychiatric disorders”
‘Mindful people’ feel less pain; MRI imaging pinpoints supporting brain activity
Ever wonder why some people seem to feel less pain than others? A study conducted at Wake Forest School of Medicine may have found one of the answers — mindfulness. “Mindfulness is related to being aware of the present moment without too much emotional reaction or judgment,” said the study’s lead author, Fadel Zeidan, Ph.D., assistant professor of neurobiology and anatomy at the medical school, part of Wake Forest Baptist Medical Center. “We now know that some people are more mindful than others, and those people seemingly feel less pain.” Continue reading “‘Mindful people’ feel less pain; MRI imaging pinpoints supporting brain activity”
Bravery cells found in the hippocampus
Why do some people comfortably walk between skyscrapers on a high-wire or raft the Niagara Falls in a wooden barrel whereas others freeze on the mere thought of climbing off escalators in a shopping mall? In a new study, scientists have found that a certain type of cells in the hippocampus play a key role. Continue reading “Bravery cells found in the hippocampus”
This is how the brain forgets on purpose
Researchers from Ruhr-Universität Bochum and the University Hospital of Gießen and Marburg, in collaboration with colleagues from Bonn, the Netherlands, and the UK, have analysed what happens in the brain when humans want to voluntarily forget something. They identified two areas of the brain — the prefrontal cortex and the hippocampus — whose activity patterns are characteristic for the process of forgetting. They measured the brain activity in epilepsy patients who had electrodes implanted in the brain for the purpose of surgical planning. The team headed by Carina Oehrn and Professor Nikolai Axmacher outlines the results in the journal Current Biology, published online on 6 September 2018.
