How Binaural Beats Affect Your Brain – and How They Don’t
2017年12月21日 · 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. ...

2024年10月1日 · Our passion is sharing exciting stories about the brain and mind. To do this, we use various modes of creative communication to discuss neuroscience simply and effectively.
The emergence of a hive mind: Should we worry? - Knowing …
2018年1月31日 · 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 ...
The Brain’s Building Blocks: Of Protons and Voxels
2017年9月27日 · The answer: A little bit of water, and a lot of something called a voxel.. An MRI machine is, per its moniker, a giant magnet. Most human research machines range from 1.5 – 3 Tesla (the unit for magnetic field strength)—this is very, very strong.This level of strong can pull up to 2000 pounds, roughly the weight of a small car.

Your brain is very complicated and fascinating! Every week for one year we posted a new and interesting fact about that 3 lb organ in your skull and other parts of the nervous system.
Hubel and Wiesel & the Neural Basis of Visual Perception
2014年10月29日 · Snap! Crackle! Pop! Those are the sounds that Professors David Hubel and Torsten Wiesel heard in the early 1950s when they recorded from neurons in the visual cortex of a cat, as they moved a bright line across its retina. During their recordings, they noticed a few interesting things: (1) the neurons fired only when the line was in a particular place on the retina, (2) the activity of these ...
This Is Your Brain on Twitter: The Neuroscience of Social Media
2022年6月15日 · Carolyn Amir is a Neuroscience PhD student at UCLA in Dr. Carrie Bearden's lab. Her current research focuses on using neuroimaging and genetics approaches to study the human brain and behavior in psychiatric and developmental disorders. Before coming to UCLA, Carolyn worked at the National Institutes of Health where she studied human pain, medication use and expectancy.
How Weight Lifting Gets the Brain in Shape - Knowing Neurons
2022年3月1日 · 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.
Excitation and Inhibition: The Yin and Yang of the Brain
2017年1月25日 · Because complex patterns of brain activity are thought to underlie flexible behavior and cognition, the ratio between excitation and inhibition — referred to as E/I balance — is becoming increasingly recognized as a crucial measure for assessing the fitness of any brain. Schizophrenia, for example, has been associated with a low E/I ratio caused by weakly active glutamate receptors.
