The emergence of a hive mind: Should we worry? - Knowing …
WEBJanuary 31, 2018 DanielToker. [dropcap]T [/dropcap]he term “hive mind” refers to the apparent intelligence that emerges at the group level in some social species, particularly insects like honeybees and ants. An individual honeybee might not be very bright (although that’s debatable), but the honeybee colony as a collective might be very ...
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 …
The Life and Times of the 10% Neuromyth - Knowing Neurons
WEBFeb 13, 2018 · These are fine speculative science plotlines until the doctor cites a version of the 10% brain myth to explain how his neurotechnology works: “Even on a good day, we only use 40% of our brain capacity.”. Of course, says the show, that leaves 60% of “empty” brain capacity. This comes from the same show which has cleverly used appropriate ...
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.
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.
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 ...
Excitation and Inhibition: The Yin and Yang of the Brain
WEBJanuary 25, 2017 Joel Frohlich. To make a working nervous system, only two forces are necessary: excitation and inhibition. Excitatory signaling from one cell to the next makes the latter cell more likely to fire. Inhibitory signaling makes the latter cell less likely to fire. At chemical [simple_tooltip content=’Connections between neurons ...
The Neuroscience of Motivation and How to Improve It
WEBSep 4, 2019 · The earliest experiments linking dopamine to motivation trace their roots back to the early 1950s when scientist Dr. James Olds discovered that electrical stimulation of the middle of the brain caused rats to repeat a given reward-seeking behavior [1]. The idea that this effect could be mediated by dopamine was later formalized by Dr. Roy Wise, whose experiments demonstrated that low levels of ...
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 ...
This Is Your Brain on Twitter: The Neuroscience of Social Media
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.
