Breath and Emotion Connected by Newly Identified Brain Circuit

Researchers have identified a specific brain circuit that allows voluntary control of breathing, linking it to emotional and behavioral states. This circuit, spanning the anterior cingulate cortex, pons, and medulla, slows breathing during calm states and accelerates it under anxiety. Experiments in mice showed activating this circuit reduced anxiety, while shutting it off increased stress.

How to Make and Break Habits Using Neuroscience

Researchers have developed a framework for understanding and changing habits by leveraging the brain's automatic and goal-directed systems. Habits form when automatic responses overpower conscious control, leading to both everyday action slips and compulsive behaviors.

Confined Spaces Change How We Smell and Experience Food

Researchers found that confined environments, like the International Space Station, alter the way people perceive food aromas, with emotions significantly coloring their responses. Using virtual reality to simulate space conditions, participants reported stronger smells for most aromas, except lemongrass, compared to a microgravity posture.

Repurposed Multiple Sclerosis Drug May Improve Memory

Fampridine, used for improving walking in multiple sclerosis, may also enhance working memory in individuals with schizophrenia or depression. A study found that the drug significantly improved working memory in participants with initially poor performance, but had no effect on those with strong baseline memory.

Social Tolerance Fuels Learning in Wild Capuchin Monkeys

Wild bearded capuchins use social learning to solve problems, influenced by social tolerance and group dynamics. Researchers observed the monkeys interacting with a puzzle-box and found that grooming partners and tolerant individuals were more likely to learn from each other.

Finger-Prick Test Brings Alzheimer’s Detection Closer to Everyone

A new Alzheimer’s test collects just a few drops of blood from a finger prick, which can be mailed to a lab for analysis. The test measures biomarkers like pTau217 and has shown similar accuracy to traditional venous blood sampling.

Ancient Gene Reprograms Stem Cells to Create a Living Mouse

Scientists have reprogrammed mouse cells into pluripotent stem cells using a gene from choanoflagellates, single-celled organisms related to animals. This breakthrough demonstrates that key genes driving stem cell formation existed in unicellular ancestors nearly a billion years ago.

Parkinson’s Tremor Linked to Dopamine in Caudate Nucleus

Rest tremor in Parkinson’s disease is linked to dopamine activity in the caudate nucleus, challenging conventional beliefs about dopamine loss and motor symptoms. Surprisingly, patients with stronger tremor preserved more dopamine in the caudate, highlighting a complex relationship between tremor severity and neural circuits.

Unique Brain Plaques Linked to Alzheimer’s Mutation Decoded

Researchers have identified the structure of amyloid beta fibrils linked to a rare inherited form of Alzheimer’s disease caused by the Arctic mutation. Using cryo-electron microscopy and NMR, they revealed a W-shaped fibril structure that explains the formation of cottonwool plaques—large, spherical brain structures unique to this mutation.

Body Image Impacts Motor Skill Learning

Self-consciousness about one’s body affects the ability to learn and perform movement tasks, according to new research. Participants recalling body-related embarrassment performed worse on motor tasks compared to those recalling pride, with the negative impact being stronger in men than women.

Dual-Gene Therapy Shows Promise for Hearing and Vision Loss

Researchers have developed a dual-gene therapy approach to treat Usher syndrome type 1F, a rare condition causing deafness and progressive blindness. By splitting the large PCDH15 gene into two halves, delivering them via adeno-associated viruses, and reassembling them in cells, the therapy restored hearing and balance in mice. Tests in human retinal organoids and primate retinas showed increased levels of protocadherin-15 in light-sensing cells, offering hope for vision preservation.
