Tech Xplore / Rolling soft electronics yields 3D brain probes for precise neuron mapping
To shed new light on the contribution of different brain regions and neural circuits to specific mental functions, neuroscientists and medical researchers rely on advanced imaging techniques and neural probes. These are electronic ...
Medical Xpress / Theory proposes key role for cortex layer 6b in attention and advanced mental functions
A layer deep in the cerebral cortex, which is the innermost layer of the mammalian brain, has recently been found to play a role in the regulation of brain states associated with wakefulness and attention.
Phys.org / The Hofstadter butterfly: Twisted bilayer graphene reveals two distinct strongly interacting topological phases
Magic-angle twisted bilayer graphene (MATBG) is a material created by stacking two sheets of graphene onto each other, with a small twist angle of about 1.1°. At this "magic angle," electrons move very slowly, which can lead ...
Medical Xpress / New insights into the epigenetic processes via which neuroinflammation causes memory loss
Neuroinflammation, a prolonged activation of the brain's immune system prompted by infections or other factors, has been linked to the disruption of normal mental functions. Past studies, for instance, have found that neuroinflammation ...
Phys.org / Gold-enhanced TiO₂ catalyst enables efficient and selective flow synthesis of propane from methane
Methane (CH₄), the colorless and odorless gas that makes up most natural gas on Earth, has so far been converted into useful fuels and chemicals via energy-intensive processes that need to be carried out at high temperatures. ...
Phys.org / Polaritons enable tunable and efficient molecular charge transfer across broader spectrum of light
Polaritons are quasiparticles emerging from strong interactions between light particles (i.e., photons) and matter excitations (e.g., excitons). Over the past few years, researchers have found that these quasiparticles can ...
Medical Xpress / Pancreatic insulin disruption triggers bipolar disorder-like behaviors in mice, study shows
Bipolar disorder is a psychiatric disorder characterized by alternating episodes of depression (i.e., low mood and a loss of interest in everyday activities) and mania (i.e., a state in which arousal and energy levels are ...
Medical Xpress / Dopamine signaling in nucleus accumbens may shape confidence in decision-making
Decision-making, the process through which humans choose between different available options, has been the topic of countless neuroscience, psychology and behavioral science studies. This process does not only include the ...
Medical Xpress / Comprehensive molecular atlas of human hippocampus maps cell subtypes and organization
The hippocampus is an important brain region known to support various cognitive (i.e., mental) processes, including the encoding and retrieval of memories, learning, decision-making and the regulation of emotional states. ...
Medical Xpress / People's brain structure linked to their genetic risk of major depression, study finds
Depression is among the most widespread psychiatric disorders, experienced by an estimated 3.8% of the global population. It is characterized by persistent low mood and a loss of interest in most activities, as well as possible ...
Medical Xpress / Stomach-brain communication predicts emotional symptoms and well-being, study finds
Internal physiological states, such as digestion, breathing and heartbeat, have been consistently linked to mental, psychological and emotional experiences. This body-mind connection is known to be supported by interoception, ...
Tech Xplore / Artificial neuron merges DRAM with MoS₂ circuits to better emulate brain-like adaptability
The rapid advancement of artificial intelligence (AI) and machine learning systems has increased the demand for new hardware components that could speed up data analysis while consuming less power. As machine learning algorithms ...
Medical Xpress / Two distinct microglia populations linked to autism-like and depression-like behaviors in mice
The anterior insular cortex (aIC) is an important brain region known to contribute to the regulation of emotions, the integration of bodily sensations, decision-making and some other functions. Past studies have linked this ...
Phys.org / MARATHON experiment offers most precise measurement of nucleon structure yet
Nucleons, which include protons and neutrons, are the composite particles that make up atomic nuclei. While these particles have been widely studied in the past, their internal structure has not yet been fully elucidated.
Medical Xpress / Microglia gene activity shifts across Alzheimer's stages, revealing possible therapy targets
Alzheimer's disease (AD) is a debilitating neurodegenerative disorder that causes progressive memory loss and a decline in mental (i.e., cognitive) abilities. Statistics suggest that between 500,000 and 900,000 people are ...
