Integrated Neurophotonics For Real-time Mapping of Brain Circuits

A new approach to dense functional imaging of brain activity, called integrated neurophotonics, is unveiled in a new paper1 from researchers at California Institute of Technology. The technique may enable the activity of all of the thousands to millions of neurons in a particular brain circuit to be observed in real time. Credit: Roukes et. al The approach uses miniature arrays of optical microchips that can be implanted at any depth inside the brain.

STAT3 In The Midbrain Modulates Emotional Reactivity

The molecule STAT3 plays an important role in the serotonergic system as a mediator for controlling emotion, new research1 from Medical University of Vienna researchers indicates. The finding points to a mechanism linking the immune system, serotonin transmission and mood disorders like depression. Previous research indicates that inflammatory processes play a key role in some psychiatric disorders. Of particular interest is the interleukin 6/STAT3 signal transduction pathway, associated with depression2, schizophrenia3, and bipolar disorder.

Why Empathy Is Important During The Covid-19 Pandemic

Margaret Mead, the famous anthropologist, was once asked what she considered to be the first signs of civilization in a culture. Her answer was not the expected weapon, clay pot, or grinding stone. It was a healed femur. She went on to explain that a healed femur bone is evidence that someone cared, someone was willing to do the injured person’s hunting and feed him or her. This individual was kept alive over an extended period of time, allowing the bone to heal.

High-calorie Foods: Are We Hardwired to Remember Them?

You are on the way to your cubicle, coming back from the cafeteria, when you run into Nick. He says he has to fly to Vancouver for a meeting with the solar panel supplier for the new power station project. Nick knows you’ve been to Vancouver a few times to visit your brother, so he asks you to recommend a couple good restaurants to hit when he’s in there. Your brain scans thru all the times you were there, cross references the places you ate, and compares them.

Brain Fog After COVID-19 Recovery May Indicate PTSD

Continuing “brain fog” and other neurological symptoms after COVID -19 recovery may be due to post-traumatic stress disorder (PTSD), a new report indicates1. Such brain fog was an effect observed in past human coronavirus outbreaks such as SARS and MERS. People who have recovered from COVID-19 sometimes experience persistant troubles with concentration, as well as headaches, anxiety, fatigue or sleep disruptions. Patients may fear that the infection has permanently damaged their brains, but researchers say that’s not necessarily the case.

The Supramammillary Nucleus: Social Novelty Has A Location In The Brain

A part of the mouse brain called the supramammillary nucleus (SuM) is specialized for detecting new experiences, researchers at the RIKEN Center for Brain Science (CBS) in Japan have found1. Within the SuM, responses to experiences related to unknown individuals — called social novelty — were separated from those related to unfamiliar places — called context novelty — before being sent to distinct parts of the brain’s main memory-formation center. The finding may further the understanding of normal memory, as well as conditions in which recognizing and reacting to new information is impaired.

Pregnancy Loss: A Possible Link Between Olfaction And Miscarriage

Unexplained repeated pregnancy loss is a poorly understood condition that can cause significant distress and for which no effective treatment exists. Much research to date has focused on dysfunctions of the uterus or hormonal signaling (Saravelos and Regan, 2014), but the possible involvement of the nervous system has not been explored despite the role of the olfactory system in mammalian reproduction being well-documented (Dulac and Torello, 2003). Exposing female rodents to the smell of adult males can lead to synchronized menstrual cycling (Whitten, 1956) and accelerated sexual maturation (Vandenbergh, 1967), as well as to embryos failing to implant in the uterus (Bruce, 1959).

The 7 Habits of Highly Serene People

Is it possible to model the habits of serenity? Would a person who is highly serene even have any habits? Or are people who are habitually calm actually living in a numbed-out cocoon? Can you genuinely feel a sense of serenity on a regular basis? Sometimes it seem like feelings of anxiety have become normal in nearly all aspects of life . People aren’t able to enjoy feelings of calmness and peace on any regular basis.
