Jan 31, 2018 · One possible answer is because that’s how large neural networks work. One popular (though largely untested) theory of consciousness is that of neuroscientist Giulio Tononi, whose information integration theory proposes that consciousness emerges wherever you have a system that is simultaneously functionally specialized and integrated, so that specific modules process specific kinds of ...

Aug 22, 2024 · Uncertainty is fundamental to human fear. Instinctually, we are wired to take the path of least perceived danger—one we feel we can most accurately predict the outcome of. In the post-modern world, this may be why we have developed behaviors such as procrastination and worrying to avoid or cope with potentially unpleasant tasks. As the spread and development of artificial intelligence (AI ...

Nov 25, 2024 · Like most psychological phenomena, surprises have an evolutionary significance. Cognitive science tells us that our brains are like little prediction machines, constantly comparing what we perceive with our own internal models of the world.

Sep 24, 2024 · By Megan (not that kind of MEG!) Hall. It’s easy to figure out what your brain looks like, but what is it actually doing? What does your brain’s activity look like? While we have many tools, like MRI, to understand brain structure, learning about brain activity is tougher.Specifically, most brain activity that scientists can measure is thought to …

Feb 1, 2017 · Caitlin Aamodt. Caitlin Aamodt is a Ph.D. Candidate in Neuroscience at UCLA in the lab of Stephanie White. Her research focuses on using songbirds as a translational drug discovery model for treating autism and other neurodevelopmental disorders.

Jan 14, 2025 · With evidence for what is preventing the aged brain from cleaning they attempted to answer this question by investigating whether it was possible for the clean up to continue, and prevent F-actin build-up in the older brain.. To answer this question, the authors designed an experiment that would let them genetically control F-actin in the flies. They targeted a gene called Formin homology 2 ...

Dec 18, 2024 · Imagine if scientists could control specific brain functions with the ease of flipping a switch. This vision is closer than ever, thanks to chemogenetics—a tool that allows scientists to precisely manipulate specific cell types or circuits that regulate behavior. The term ‘chemogenetics’ combines ‘chemo-’ for drug-based activation and ‘genetics’ for the use of engineered receptors.

Nov 27, 2024 · I was around twelve when I first realized that I couldn’t tolerate the sound of people eating, fifteen when I discovered that this was a disorder known as “misophonia,” and in college when I first began looking into the research on the condition. My father’s crunching, my mother’s sniffling, my classmates’ gum-smacking - all of …

Dec 21, 2017 · One way in which binaural beats may influence brain waves is through entrainment. Entrainment here means that the activity of your EEG becomes similar to a certain frequency set by an external stimulus. An example of entrainment is repetitive clicks: if you hear clicks at a certain frequency, your EEG is likely to show waves at this same frequency. ...

Mar 1, 2022 · Astoundingly, weight training has been shown to protect subregions of the hippocampus—a brain region involved in cognition and long-term memory—from degeneration in populations at risk for Alzheimer’s Disease (e.g., Broadhouse et al, 2020). This neuroprotective effect helps explain the cognitive and memory benefits of resistance exercise.
