The Neuroscience of Bass: New Study Explains Why Bass Instruments Are Fundamental to Music. Photo by Sebastiaan term Burg via Wikimedia Commons At the lower range of hearing, it’s said humans can hear sound down to about 20 Hz, beneath which we encounter a murky sonic realm called “infrasound,” the world of elephant and mole hearing.
But while we may not hear those lowest frequencies, we feel them in our bodies, as we do many sounds in the lower frequency ranges—those that tend to disappear when pumped through tinny earbuds or shopping mall speakers.

(Teale J and O’Connor A (2015) What is Déjà vu?. Front Young Minds. 3:1. doi: 10.3389/frym.2015.00001) Déjà vu describes the strange experience of a situation feeling much more familiar than it should. Young people experience déjà vu the most. Many of us report our first experiences between the ages of 6 and 10. Are Implanted False Memories Permanent? No memories are permanent.
In fact, recent understanding is that no memory is actually factual. When we recall a memory, it's as if our brain pulls up a report and outlines it to our consciousness, which subsequently relives it, usually incorporating slight inaccuracies, and the recollection is stored along with the original - and we can't tell the difference between them.
The experience of reliving it becomes as real to us as the original memory. This means the recalled memory (along with any inaccuracies) becomes merged with the source memory, which becomes increasingly inaccurate the more often it is recalled. It's like a sort of wish fulfillment, smoothing out rough edges and amplifying the emotions we most want to recall *about* the memory. Our brains deliberately make us forget things, to prevent insanity. Even People With “Perfect Memory” Can Be Tricked Into Recalling Fake Events. When neurons misfire: Those who can remember what they ate for lunch on a day ten years ago can be fooled by tests that distort memories.

Their EEG activity, which measured NREM sleep, fell by 30%. Their melatonin levels were lower and they reported feeling less rested the following day. All of them? Really? Memory implantation is now officially real. In this study, the mouse is now afraid of an environment in which it never received pain, and would therefore not associate pain with it.
By artificially activating the neurons associated with the pain-free environment in a new context with a foot shock, a fear response is now elicited the original context where no shock or pain occurred. The experiment takes advantage of associations, but uses optogenetic activation to make the mouse remember shock where shock never occurred (false memory). But the environment could be similar enough that it thinks it may be get a shock anyways. umm, yeah, but the mouse still recieved pain from simply thinking of or remembering the environment. Imagine it this way. Of course you would be scarred shitless if you were forced into this bedroom, which the simple act of thinking of causes physical pain. The conclusion that it created a false memory is a huge assumption. People in a vegetative state may feel pain - health - 23 February 2013. IT IS a nightmare situation.

The activity of a single neuron is captured in unprecedented detail by this footage, which is so fine-grained that individual proteins can be seen shuttling in and out.
Captured on microscope and illuminated by bioluminescent proteins, the video represents a methodological improvement that allows imagers to focus on individual pathways inside the cell. That prevents overlapping pathways from being simultaneously and confusingly illuminated. The study describing the method was published in July in Cell Reports. Video: Bioluminescent proteins illuminate the activity of a single neuron. (Arnold et al. Decision-Making and Control in the Brain. Damage to the brain's frontal lobe is known to impair one's ability to think and make choices. And now scientists say they've pinpointed the different parts of this brain region that preside over reasoning, self-control and decision-making.
Researchers say the data could help doctors determine what specific cognitive obstacles their patients might face after a brain injury. For the study, neuroscientists at the California Institute of Technology (Caltech) examined 30 years worth of data from the University of Iowa's brain lesion patient registry and mapped brain activity in almost 350 people with lesions in their frontal lobes. They linked these maps with data on how each patient performed in certain cognitive tasks. Researchers show that memories reside in specific brain cells. Our fond or fearful memories — that first kiss or a bump in the night — leave memory traces that we may conjure up in the remembrance of things past, complete with time, place and all the sensations of the experience. Neuroscientists call these traces memory engrams. False memories generated in lab mice - life - 22 March 2012. Why does falling asleep sometimes feel like falling down?
Infinity Imagined. Infinity Imagined. Infinity Imagined. The 4 Biggest Myths About the Human Brain. Perhaps a wrinkle to your summary? Not quality or quality - structure. Our neurons aren't fundamentally 'higher quality' than a rodent's; the nature of neuron scaling implies a difference in the way they are packed, and their pattern of connectivity. Requiring more space, a rodent's brain must be filling with 'other stuff' quickly - perhaps glial tissue, for rapid response time despite a larger brain=longer processor cycles? Primates may be more contemplative, with a few, well-trimmed, long-dendrite neurons slowly linking abstract thoughts.
Equating our intelligence with necessary forms in machine intelligence conflates two problems: understanding our own cognition, and developing models and machines to solve the problems we can't or won't. Next question: Nature is only able to explore those structures and functions which appear in the environment, and can only move to the adjacent possible. If we remember more, can we read deeper–and create better? Part II. Is memory essential for creativity?

How many calories does thinking burn? Why The Left-Brain Right-Brain Myth Will Probably Never Die. Why Some People Can Recall Life's Every Moment. Can you remember what you ate for lunch on March 8, 1999? What about what you were wearing on Oct. 29, 1985? A handful of people — only 33 confirmed to date — can remember such minutiae, recalling almost every moment of their lives after about age 10 in near-perfect detail. They have what scientists call a highly superior autobiographical memory, and now researchers have identified what makes their brains special. Researchers at University of California, Irvine (UCI) studied 11 people with the condition and flagged distinct quirks in nine structures of their brains.
If we remember more, can we read deeper–and create better? Part I. The genes behind human intelligence also made us vulnerable to autism. Humans Evolved Big Brains to Be Social? How Our Brains Make Memories. Sitting at a sidewalk café in Montreal on a sunny morning, Karim Nader recalls the day eight years earlier when two planes slammed into the twin towers of the World Trade Center. He lights a cigarette and waves his hands in the air to sketch the scene. At the time of the attack, Nader was a postdoctoral researcher at New York University. He flipped the radio on while getting ready to go to work and heard the banter of the morning disc jockeys turn panicky as they related the events unfolding in Lower Manhattan. Is Your Brain Liberal Or Conservative? The political differences between liberals and conservatives might run as deep as the brain, researchers suggest. Scientists had previously found that some psychological traits were associated with certain political views.
For instance, studies have shown that conservatives tend to be more sensitive to threatening faces, while liberals tend to be more open to new experiences. Political ideology has even been found to leave its footprint in how we set up our bedrooms and offices, with liberals' offices judged as significantly more distinctive, comfortable, stylish and colorful than conservatives' offices. Cognitive neuroscientist Ryota Kanai of the University College London and his colleagues reasoned that such fundamental differences in personality might be seen in the brain. Neuroscientists identify a master controller of memory.

Oct. 19 (Bloomberg) -- People who have more Facebook friends have more gray matter in their brains, a finding that may spur further research on the relationship between social networking and the mind, U.K. researchers said. A strong correlation was found between the number of Facebook connections and the amount of gray matter, or brain tissue responsible for processing signals, according to research led by Geraint Rees, a senior clinical research fellow at University College London. The results, based on magnetic resonance imaging of 125 college students’ brains, was published today in the journal Proceedings of the Royal Society B. The Facebook Brain. People with lots of Facebook friends have denser grey matter in three regions of the brain, a study suggests.
