Anatomy, Physiology and Neuroscience

I've been noticing that the people seem to be much less reasonable in their thinking these days, as compared to periods like 10-20 years in the past. I also happened to come accross a couple of articles about studies and/or standard tests that appear to agree. The only hypothesis I saw given in the articles was that it has been suggested by a few that weve reached our evolutionary peak which is about as random a reason for an excuse some concern as I can think. Other examples that would seem like clear indicators to me are the divergence of peopleles opinions most evident in politics, but also across all sectirs it seems. Theres even a trend to elect dumber p…

The discovery of mirror neurons (twenty years ago) in the brain on macaque monkeys is controversial. In particular, the biological mecanism of "shared neural activations" has been proposed as a model to understand the concept of "cognitive empathy". What if human consciousness can sense the mental states of others by expressing empathy? Can we teach artificial intelligence to share empathy with humans?

Assuming memory formation is genetic, can cognitive memory be improved by the activation of synaptic plasticity?

This article, entitled Patterns of Inverted Reading and Subgroups in Dyslexia, appeared in The Annals of Dyslexia (a peer reviewed scientific journal) in the mid 80's. Below you will find a summation of the study which I did a few years ago - but I'm not a scientist. Could someone read the article and tell me if my conclusions are correct. https://link.springer.com/article/10.1007/BF02663620 Here's what I came up with: The study, which was conducted in Denmark by Larsen and Parlenvi and published in the Orton Dyslexia Society’s Annals of Dyslexia in 1984, was originally intended to determine the significance of the direction in which reading is carried out. In other word…

i watched a video of ginkgo saying drinking ginkgo biloba tea for a couple of weeks/months improves memory. is it real ? From what i searched in internet, i found two different answers, which one is right ? Taking gingko biloba does not improve memory, study finds https://www.sciencedaily.com/releases/2012/09/120924080513.htm Can Ginkgo biloba prevent memory loss and improve cognitive function?http://www.mayoclinic.org/diseases-conditions/alzheimers-disease/expert-answers/ginkgo-biloba-memory-loss/faq-20058119 Ginkgo biloba: Health benefits, uses, and risks http://www.medicalnewstoday.com/articles/263105.php https://www.drweil.com/vitamins-supp…

in which part of the body or where are specifically the dorsal nerve cord and notochord human have ?

I want to know hypothetically, if a person was to buy two nitrogen tanks and then put it inside the trunk of his car, and then hop into the trunk and close it while leaving the nitrogen tanks on and staying in the trunk overnight, would this person die due to the nitrogen displacing the available oxygen in the trunk? And is it true that when someone inhales nitrogen, their body won't be able to tell the difference from oxygen which would mean the person wouldn't have any choking or suffocating sensation since the suffocating sensation is due to the build up of carbon dioxide in the body? Can the human body expel carbon dioxide if nitrogen is inhaled? Is this true? If the …

It appears the role of the AKT1 genotype has been implicated in THC tolerance. Interestingly, delta9-tetrahydrocannabinol (THC) may activate the AKT1 gene in vitro and in vivo. This pharmacological activation of the AKT1 gene by THC might explain why THC administration is neuroprotective in Alzheimer's disease.

Hi everybody! Does anyone know why does glucagon stimulate pancreatic beta-cells to secrete insulin? I have searched many articles, but I haven't found an answer.... I know that beta-cells have glucagon membrane receptors and that they work activating cAMP production, but what is the physiological translation of this? Why is glucagon an insulin secretagogue? Isn't high blood glucose concentration enough stimuli? I hope that someone can help me with this...

I'm 19. Just 2 weeks ago, i remember seeing a white flash/spot in my right eye a few times a day, this one was rather large than the ones i get now, and it lasted longer about 3 seconds. It would move as i moved my eye. Now, i get these white flash/spots in my vision constant all day, but they'll last briefly and are smaller. These blue lights will arrive especially when i look away from my laptop screen at the wall, or if i indirectly point my sight toward a light source. I'll get multiple of these blue spots that will stick like dead flies and last indefinitely. They'll appear strongest when i move my eyes or blink. Not just blue, but mostly other white spots. For e…

Hi. For surgeons?... What is behind the belly button inside an adult abdomen ? Seems there is something holding it 'pulled-in'. What connecting tissues exist attached to what organs/parts ?

Scientists say they have located the parts of the brain that control religious faith... Was there not some news stories going around where some one was really religious zealous going to church every day than got a brain injury than stop believing in God? And other case an atheist got a brain injury than out no where started believing in God?

Hi everyone, I'm an audio engineer (not a neuroscientist) and I'm wondering how I could find out more about "higher levels" of sound processing in the brain. I've noticed, for example, that I can be lost in thought in a quiet room, then suddenly listen outwardly and it feels as if someone has stopped talking. So if anyone has any suggestions for books on how the brain deals with sounds beyond the ears, I'd appreciate it. Most texts end with "and signals are converted to electrical impulses and 'sent to the brain'" I'd like to know what happens after tha. Thanks, -Matt

Hey yall, I just have a few questions to ask in regards to different motions of the body. 1. Is shoulder abduction synonymous with scapular upward rotation? 2. Conversely, is shoulder adduction synonymous with scapular downward rotation? 3. Some people (including myself) have the additional ability to "tilt" their scapula on will... is anyone aware of the primary muscles responsible for this? (Bonus: or have cues on how to coach someone to be able to do this.) 4. Reading through my text books, I've found several muscles described to perform "ipsilateral" or "contralateral" rotations. I understand that ipsilateral refers to same-sided (like right foot and right h…

Obviously, it's my first post. I have been looking around seeing if I can find some ideas on how the brain "makes" images. The light bounces off an object, eyes pick it up, and the brain processes it in what I believe is the visual cortex. But after it's processed, what is the final product in which I am seeing? Is it a collection of nerves, magnetic waves, quanta that form into that external object that was perceived? Would it be like if there was a monitor in my head which receives the processed visual information and is shown as a bunch of pixels?

I think that dreams could be hallucinations because when you're dreaming, you don't experience with your body any of the 5 senses. The brain could start making up things. People that were placed in isolation chambers had hallucinations for the same reason. What do you think?

I know there is much debating on whether cannabis can cause the onset of schizophrenia but what are the scientific reasons for the claims?

I'm wondering what you all think about the current state of the neuroscience of creativity. Personally, as someone chiefly interested in phonological neuroscience and how it relates to poetry through language and music through sound, this field holds the greatest possible intrigue for me. At the same, I think the level of science reporting, and even the assumptions made first-hand in research articles, is below even the average of other science journalism, which we all know is low. My main gripe is that I think researchers and science writers alike are implicitly pandering to a self-help culture by jumping on evidence such as blue computer screens or alcohol drinking …

Well, we have all seen the research and articles that claim dopamine (D) is increased when chocolate is consumed. But let's examine a step further as most articles I've read have been lacking in control and quality. D causes us to feel good. Yeah? But, does feeling good, or doing/eating something we like, cause D to rise? If so, isn't it a possibility that when someone who loves chocolate consumes it, the D levels rise but it's not necessarily the chocolate causing this, and instead the act of doing something rewarding? Consider: would the D levels still rise in someone who despises chocolate? That seems to contradict itself as you wouldn't be "feeling good" if you we…

My human memory erasing machine idea can see seen on Googles Quora forum website. The link is below for you to see the idea. https://www.quora.com/Can-I-have-only-some-memories-erased-from-my-brain/answer/Nicholas-Ryan-26 The idea works by combining the yet to be built latest MRI machine (for imaging Neuro disease Using high-field MR, And Contrastophores) which can image a area of about 0.1mm, or 1000 neurons, and see changes occuring as fast as one-tenth of a second. Combining it with the latest CT scanners with Magnetoencephalography (MEG), and Electroencephalogram (EEG) to see the electro signals, happening in real time. Magnetoencephalography, the SERF (spin exc…

Does meditation override the action of adrenagernic receptors and control tension ?

The effects of cannabinoids on neural communication (synaptic plasticity) are poorly understood. Does cannabinoids (THC) fine-tune or disrupt neural oscillations in the gamma range? I find the hypothesis that THC may disrupt neural oscillations pretty much obsolete as there no evidences of disruption of synchrony by exogenous THC administration.

Hello I'm a master degree student of physiology and got confused and have no idea about my thesis which should be about "memory" and "addiction" topics. I would be appreciated for your help and ideas and love to engage about it. thanks

Does anybody tried to speculate about human mind (intelligence, imagination etc.) or to emit some hypothesis of what could be ? particles or something else ... ? What are the perspectives in that direction ?

Hi there, I am currently learning about membrane potentials in a physiology class, but I'm having a little trouble. I understand that differences in concentration of an ion creates a chemical gradient, and that as these ions move across the membrane, an electric potential is created. The electric potential that exactly counterbalances the chemical force is the equilibrium potential. That much I'm okay with. We went over the Goldman Equation (as seen in the attachment I have provided), and the key takeaway here is that membrane potential is mostly affected by those ions which are most permeable. This makes sense when thinking about the fact that if ions have the abilit…
