Transcription factors (TFs) are proteins that bind to specific DNA sequences, regulating the transcription of genetic information from DNA to messenger RNA (mRNA). These proteins play a pivotal role in the regulation of gene expression, which in turn impacts a wide...

Nf1 gene mutations disrupt brain cell plasticity and motor learning in mice
Neurogenetic disorders, such as neurofibromatosis type 1 (NF1), are diseases caused by a defect in one or more genes, which can sometimes result in cognitive and motor impairments. Better understanding the neural underpinning of these disorders and how they affect...
Stimulating the medial prefrontal cortex changes a person’s perceived attractiveness, study suggests
Humans typically perceive others and themselves as more or less physically attractive, yet the neural underpinnings of these attractiveness-related perceptions remain widely unexplored. While some past studies found that stimulating the brain, particularly the medial...
NG2 glia cells shown to protect against prion-induced neurotoxicity and neurodegeneration
Neurodegenerative diseases, including Alzheimer's disease (AD) and Parkinson's disease (PD) are highly debilitating medical conditions arising from a combination of genetic and environmental factors. Studies exploring the neural underpinnings of these diseases and how...
An ingestible device to record gastric electrophysiological activity
Recent technological advancements have enabled the development of new cutting-edge medical devices, including surgical robots, sensors that can monitor physiological processes and VR platforms to train doctors. A long-standing goal for medical technology engineers is...
How the human hippocampus contributes to value-based decision-making under uncertainty
Value-based decision-making is the process through which humans choose between options associated with different costs or efforts, as well as rewards. These choices include, for instance, selecting different products at the grocery stores or making substantial...
Probing the effects of visual distraction during natural behavior using VR technology
Humans are innately well-equipped to complete procedural tasks, such as following a recipe and assembling furniture. While completing these tasks, however, people can sometimes encounter visual distractors, such as irrelevant ingredients in the same cupboard as those...
Study finds social interactions and olfactory cues prompt contagious itch in mice
Humans and other mammals can sometimes experience itch, an uncomfortable sensation that prompts them to scratch specific parts of their bodies. Past studies on humans and other primates have found that itch can sometimes be contagious.
Study shows orexin neurons can track how fast blood glucose changes
The concentration of glucose in the blood of humans continuously changes in response to what they eat and the activities they engage in. While many studies have investigated changes in blood glucose, the role of different neurons in tracking and predicting these...
Study shows that opportunity costs influence when people leave social interactions
Psychology researchers and neuroscientists have been trying to understand the principles guiding social interactions for decades. While their studies have yielded interesting results, many questions remain unexplored or unanswered.
