How Binaural Beats Affect Your Brain – and How They Don’t
WEBDec 21, 2017 · Another way binaural beats may influence your brain waves is through phase synchronization. It has been suggested, but not thoroughly tested, that auditory beats increase the synchronization of the phase of brain waves in different brain regions. One study tested the effect of binaural beats on EEG rhythms in epilepsy patients.
The Default Mode Network and Depression - Knowing Neurons
WEBDec 20, 2020 · People with anxiety and depression tend to replay upsetting scenes over and over in their minds to the point of obsession. It’s a thinking pattern that quite literally has them spinning. A meta-analysis published this year (Zhou et al., 2020) identifies the Default Mode Network (DMN) as the “principal neural substrate of rumination.”.
The Consequences of Illusory Superiority - Knowing Neurons
WEBFeb 6, 2017 · The Consequences of Illusory Superiority. February 6, 2017 Kate Fehlhaber. On January 6, 1995, a large five-foot-six 270-pound middle-aged man robbed two Pittsburgh banks in broad daylight. He didn’t wear a mask or any sort of disguise. And he smiled at surveillance cameras before walking out of each bank.

Reverse Inference: Neuroscience’s Greatest Fallacy?
WEBFeb 12, 2014 · A spectacular recent example of the misuse of reverse inference is that of James Fallon, who used a brain scan to diagnose himself as a psychopath. Fallon noticed that a scan of his own brain, taken during a study on dementia, had abnormally low activity in some frontal lobe areas. Other research has …
Can Neuroscience Explain the Mandela Effect? - Knowing Neurons
WEBFeb 1, 2017 · There are probably several main reasons for the Mandela effect. The first is that a large number of general associations increase the probability that a false memory could emerge. Twin films with similar concepts being released at around the same time were common in the ’90s.

WEBJun 15, 2022 · 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.
The Spectacularly Colorful World of the Mantis Shrimp
WEBJun 22, 2016 · Neurons in our eyes compare the responses of different types of cones in an antagonist manner. This opponent process allows us to quickly record the differences between different cone responses. In mantis shrimp, the cone types work independently of each other, without complicated neural computations. Although this …
Inhibitory Neurons: Keeping the Brain’s Traffic in Check
WEBNov 5, 2014 · When activated, inhibitory neurons release the neurotransmitter GABA, which is known to hyperpolarize the postsynaptic neurons, i.e. it makes the membrane potential more negative, making it harder for the neuron to reach the threshold to fire an action potential, thereby causing ‘ inhibition ’. Most often, inhibitory neurons are also called ...
Hubel and Wiesel & the Neural Basis of Visual Perception
WEBOct 29, 2014 · 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 ...
